pastizales naturales. El suelo bajo estudio se clasificó como Psammacuent típico. Se empleó un diseño completamente aleatorizado, tres tratamientos con cuatro repeticiones. Se tomaron muestras de suelos compuestas de 0–30 cm. Los tratamientos fueron: a) Pastizal natural (TPN); b) Pinus taeda de 7 años (PMP); c) Pinus taeda de más de 15 años (PLP). Se determinó pH edáfico en H2O (1:2,5), carbono orgánico del suelo (COS, Walkey & Black), nitrógeno total edáfico (NTS, Kjedahl), fósforo disponible (Pas, Bray Kurtz I) en el suelo y densidad aparente edáfica (método del cilindro). Los datos fueron procesados mediante software R. Se realizó un ANOVA y prueba de comparación de medias Tukey con nivel de significancia al 5 %. Se observó una disminución del pH del suelo en las plantaciones de pino, medias de 4,4 en PMP, 4,5 en PLP y 4,9 en TPN. Para el contenido de COS se encontró la serie PMP>TPN>PLP, con medias de 26,3; 22,5 y 12,8 Mg C ha-1 respectivamente; el Pas fue TPN=PMP>PLP (0,043, 0,047, 0,027 Mg P ha-1); y para NTS se encontró diferencia estadística significativa entre PMP y PLP. Se concluye que la implantación de coníferas en suelos arenosos acidifica el suelo y provoca una disminución a largo plazo de los contenidos de COS y, en consecuencia, una disminución de los nutrientes directamente relacionados con el mismo (como lo son el NTS y el Pas).</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="f9cb178a26641d56dc45b514a4430cdc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":72306045,"asset_id":57369104,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/72306045/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="57369104"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="57369104"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 57369104; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=57369104]").text(description); $(".js-view-count[data-work-id=57369104]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 57369104; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='57369104']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "f9cb178a26641d56dc45b514a4430cdc" } } $('.js-work-strip[data-work-id=57369104]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":57369104,"title":"Acidificación y pérdida de fertilidad de suelos en una secuencia forestal (Complejo Iberá-Corrientes)","translated_title":"","metadata":{"abstract":"El objetivo de este trabajo fue evaluar variables edáficas tras el reemplazo de pastizales naturales.

El suelo bajo estudio se clasificó como Psammacuent típico. Se empleó un diseño completamente aleatorizado, tres tratamientos con cuatro repeticiones. Se tomaron muestras de suelos compuestas de 0–30 cm. Los tratamientos fueron: a) Pastizal natural (TPN); b) Pinus taeda de 7 años (PMP); c) Pinus taeda de más de 15 años (PLP). Se determinó pH edáfico en H2O (1:2,5), carbono orgánico del suelo (COS, Walkey \u0026 Black), nitrógeno total edáfico (NTS, Kjedahl), fósforo disponible (Pas, Bray Kurtz I) en el suelo y densidad aparente edáfica (método del cilindro). Los datos fueron procesados mediante software R. Se realizó un ANOVA y prueba de comparación de medias Tukey con nivel de significancia al 5 %. Se observó una disminución del pH del suelo en las plantaciones de pino, medias de 4,4 en PMP, 4,5 en PLP y 4,9 en TPN. Para el contenido de COS se encontró la serie PMP\u003eTPN\u003ePLP, con medias de 26,3; 22,5 y 12,8 Mg C ha-1 respectivamente; el Pas fue TPN=PMP\u003ePLP (0,043, 0,047, 0,027 Mg P ha-1); y para NTS se encontró diferencia estadística significativa entre PMP y PLP.

Three soils from fields that mainly contribute to the economy of Corrientes were selected. A simple random sampling of two treatments and five replicates was conducted in each soil order, each replicate were a composed samples from 0-15 cm depth. Samples were selected from: 1) Entisoll: native grassland vs. citrus field, 2) Alfisoll: native grassland vs. rice crop, 3) Vertisoll: native grassland vs. Setaria sp. pasture. The parameters analysed were: texture, pH, organic carbon, calcium, magnesium, carbonate, iron and aluminium in oxalate, available phosphorus (P Bray I) and phosphorus (P) fractionation by Hedley et al. (1982) Method modified by Sattell and Morris (1992). Total P was calculated as the total addition of each phosphorous fraction. The smallest total P detected was observed in Entisolls (71.46 mg P kg-1 soil), followed by Alfisolls (126,84 mgP kg-1 soil) and Vertisolls (142.28 mgP kg-1 soil). The most predominant fraction of total P was the organic phosphorus in sodium hydroxide (53%, 54% y 48% respectively for each order). Fertilization decreased available P, but increased moderately labile and resistant phosphorus fractions in Entisolls. Only P fraction from inorganic phosphorus in microaggregates and residual organic in Alfisolls were increased under rice crop production. The implantation of Setaria sp. with fertilization in Vertisols raised the occluded organic phosphorus in the microaggregate fraction.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="e4fdc6c4dad60c49084e61b55d42aa97" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":105159904,"asset_id":105788844,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/105159904/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="105788844"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="105788844"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 105788844;

En este trabajo se presentan los resultados de las actividades de prospección y excavación desarrolladas. Como resultado de las mismas, se identificaron 11 áreas en las que los materiales arqueológicos se presentan en densidades variables y asociados a una matriz sedimentaria con alta proporción de conchillas. En líneas generales, estas se caracterizan por la presencia de material cerámico, lítico, restos óseos humanos y faunísticos, ornamentos, entre otros. A esta información, se integran y discuten los antecedentes para el sector, confirmando el alto potencial arqueológico del área.

La inoculacion con P56 seleccionadas para aumentar la poblacion nativa puede movilizar P a partir de fuentes poco disponibles y por lo tanto mejorar la nutricion de las plantas. El objetivo de este estudio fue evaluar el efecto de la inoculacion sobre las distintas formas de P en suelo, asi como sobre la absorcion de P por las plantas de naranjo (Citrus sinensis) variedad Newhall. La inoculacion evidencio un efecto positivo sobre la nutricion vegetal al incrementar el contenido foliar de P. Este incremento fue mas notable en los ensayos inoculados y fertilizados.

Se seleccionaron tres forestaciones, cada una formada por 12 parcelas y cada parcela, constituida por un árbol dominante. Se midió el diámetro a la altura del pecho (DAP) y la altura de fuste. Se muestreó el suelo a 0-7; 7-30; 30-60; 60-90; 90-120 y&gt;120 cm de profundidad. Se realizaron análisis de pH en agua y en KCl, conductividad eléctrica (CE); Ca2+, Mg2+ y Na+ solubles; y se calculó la Relación de Absorción de Sodio (RAS). Las concentraciones elevadas de la CE se observaron en el horizonte superficial con valores promedios de 1,61 dS m-1, disminuyendo con la profundidad y la RAS en superficie arrojó valores promedios de 5, 92 aumentando en profundidad de 30.

Plant yield, N and P acquisition, mycorrhizal colonisation, rhizobial nodulation and root length were measured and root diameter and root surface area were calculated after two harvests. Species responded differently to specific nutrients when grown pure or mixed. Comparing pure with mixed stands in soils fertilised with P and N + P, L. tenuis showed decreased shoot and particularly root biomass, whereas F. arundinacea showed increases in both biomasses.

El objetivo de este trabajo fue evaluar los cambios que se producen en las formas inorgánicas y orgánicas del P por el agregado de este elemento. Se planteó como hipótesis que en condiciones de suelos altamente meteorizados el P agregado se incorpora en el corto plazo a las formas inorgánicas y orgánicas lábiles; luego de un año pasa a los reservorios más resistentes. Se seleccionaron Alfisoles, Ultisoles y Oxisoles de la provincia de Misiones donde se obtuvieron muestras de los horizontes superficiales para el establecimiento de un ensayo en invernáculo. Se aplicaron tres tratamientos de P con tres repeticiones. Luego de un período de estabilización, se tomaron muestras periódicamente hasta el año, para el análisis de la fracciones de P por el método de Hedley modificado por Sattell y Morris. Las condiciones de incubación, con fluctuaciones en las condiciones de humedad, provocaron incrementos en las fracciones Pi-NaHCO 3 , Pi-NaOH y Po-NaOHus para los tres órdenes, a partir de la disminución, principalmente, del Po-NaHCO 3 y de las fracciones residuales. El fertilizante agregado en los primeros 120 días incrementó las fracciones inorgánicas lábiles y moderadamente lábiles (Pi-NaHCO 3 y Pi-NaOH). A partir de los 60 días, el Pi-NaOHus comenzó a manifestar el efecto de las distintas dosis de P, alcanzando su máximo valor a los 120 días, pasando a partir de ese momento a ser fuente del elemento agregado. El P proveniente del fertilizante, que al principio de la experiencia se ubicaba en las fracciones más lábiles, con el correr del tiempo pasó a formas más resistentes, alcanzando los valores máximos a los 360 días.

The biomass of tomato plants decreased with increasing As concentration in irrigation water, especially tomato berries. In addition, the reduction of biomasses was significantly greater in plants non-fertilized with P. The beneficial effect generated with the P addition indicated that this nutrient played an important role in alleviating As toxicity in tomato plants. The higher the As concentration in irrigation water the higher the As concentration in plant tissues; most of the As absorbed by plants was accumulated in their roots. Phosphorus application has allowed to reduce As translocation toward tomato berries, enhancing plant P status. These observations may be useful for certain areas of the World, in which As-contaminated waters are used for agricultural purposes.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="6e92e464f696f5ae33676f3a2de62108" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":89131775,"asset_id":83947651,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/89131775/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="83947651"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="83947651"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 83947651;

Nutrients cycling is a fundamental component in the functioning of forest ecosystems. Leaves of different forest species observe specific chemical composition, and some seasonal differences in biomass production, may be related to climate fluctuations and/or changes in plant phenology and the variation on nutrient contents. The objective of this study was to analyze the seasonal variability of Fe, Mn, Cu and Zn concentrations in leaves of Gleditsia amorphoides (Ga); Patagonula americana (Pa); Maclura tinctoria (Mt) and Astronium balansae (Ab) from Colonia Benítez Strict Nature Reserve (Chaco, Argentina). The leaves of each forest species were collected monthly, dried at 70ºC and their weight by tree species were recorded. Samples for analytical determinations were prepared by humid oxidation of organic substances from vegetal nets, using oxidant acids such as ternary mixture of HNO 3-H 2 SO 4-HClO 4. After digestion, total micronutrients leaves concentrations were determined by atomic absortion spectrophotometry. Leaves Fe highest values were detected during fall in Mt (76.1mg/kg), Pa (75.2mg/kg), Ab (59.5mg/kg) and Ga (45.3mg/kg). Highest foliar concentrations of Mn were detected in Pa (54.0mg/kg), Ga (50.0mg/kg), Mt (48.0mg/kg), and Ab with the lower Mn concentration (39.7mg/ kg). No significant differences were found for Cu between the different forest species, standing for Pa (11.3mg/ kg), Ga and Mt (11.0mg/kg) and Ab (10.4mg/kg). With regard to leaves Zn, highest concentrations were found in Mt (347.4mg/kg), Ga (319.9mg/kg), Pa (280.2mg/kg) and Ab (255.7mg/kg). Generally, a marked seasonal variation was observed for Mn and Cu concentrations (except in Ga) and Zn (except in Pa), with no statistical differences for Fe. in the species studied, the concentration of micronutrients analyzed showed a marked and erratic seasonal variation, attributed to the relationship established between the native species, and the strong influence of the environment over a long period of time, especially temperature and rainfall.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="2c90a3dee2045ed6430250ac8f7a8932" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":89131772,"asset_id":83947650,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/89131772/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="83947650"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="83947650"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 83947650;

Debido a la variabilidad en la evaluación de la disponibilidad de P en el suelo, se realizó este trabajo con el objetivo de: a) comparar entre sí dos de los métodos más comunes de evaluación de disponibilidad de P del suelo (Bray I y Olsen), y el método de la tirita de papel de filtro embebida en óxido de hierro (Strip); b) estimar cual de los métodos se relaciona mejor con algunas variables vegetales ante distintas condiciones de manejo y tipos de suelos. Se estudiaron suelos de los órdenes Entisol, Alfisol y Vertisol de la provincia de Corrientes en condición natural o cultivado con Citrus, arroz o pasturas, respectivamente. Se determinaron algunas propiedades físicas y químicas, verificando la similitud textural entre los suelos Testigos y Cultivados. Se realizó un ensayo en invernadero de cada uno de los seis suelos con once niveles de P (entre 0-200 mg P por kg de suelo) y luego se los incubó durante 25 días a 28 o C. Al finalizar la incubación se determinó el P disponible mediante los procedimientos recomendados para los métodos de Bray I, Olsen y Strip. Se sembró "rye grass" (Lolium perenne) que se cosechó a los 45 días de la siembra para cuantificar la materia seca aérea y análisis de P en tejido. Los resultados obtenidos en este trabajo sugieren que todos los métodos de evaluación de la disponibilidad de P del suelo describieron de manera adecuada y significativa las relaciones entre MS (R 2 entre 0,35 a 0,95, y valores extremos para el Vertisol y el Entisol), %P (con R 2 entre 0,92 y 0,95) y P absorbido (R 2 entre 0,93 y 0,96 y con muy pocas diferencias entre los suelos) con el P extractado por los tres métodos. Sin embargo, la bondad de los ajustes fue diferente entre suelos, extractantes y manejos productivos, y sugieren la existencia de una interacción tripartita que arroja diferentes resultados en el valor final del P disponible. Se concluye que, no necesariamente el método más sencillo en la evaluación de P disponible para el vegetal es el que mejor refleja la relación con la materia seca o con la concentración del P en el tejido.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="913964dfb81def87fc3d83b7026ba428" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":89131777,"asset_id":83947647,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/89131777/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="83947647"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="83947647"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 83947647;

Se seleccionaron tres forestaciones, cada una fonnada por 12 parcelas y cada parcela, constituida por un árbol dominante. Se midió el diá111etro a la altura del pecho (DAP) y la altura de fuste. Se muestreó el suelo a 0-7; 7-30; 30-60; 60-90; 90-120y&gt;120 cm de profundidad.

Three soils from fields that mainly contribute to the economy of Corrientes were selected. A simple random sampling of two treatments and five replicates was conducted in each soil order, each replicate were a composed samples from 0-15 cm depth. Samples were selected from: 1) Entisoll: native grassland vs. citrus field, 2) Alfisoll: native grassland vs. rice crop, 3) Vertisoll: native grassland vs. Setaria sp. pasture. The parameters analysed were: texture, pH, organic carbon, calcium, magnesium, carbonate, iron and aluminium in oxalate, available phosphorus (P Bray I) and phosphorus (P) fractionation by Hedley et al. (1982) Method modified by Sattell and Morris (1992). Total P was calculated as the total addition of each phosphorous fraction. The smallest total P detected was observed in Entisolls (71.46 mg P kg-1 soil), followed by Alfisolls (126,84 mgP kg-1 soil) and Vertisolls (142.28 mgP kg-1 soil). The most predominant fraction of total P was the organic phosphorus in sodium hydroxide (53%, 54% y 48% respectively for each order). Fertilization decreased available P, but increased moderately labile and resistant phosphorus fractions in Entisolls. Only P fraction from inorganic phosphorus in microaggregates and residual organic in Alfisolls were increased under rice crop production. The implantation of Setaria sp. with fertilization in Vertisols raised the occluded organic phosphorus in the microaggregate fraction.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="e4fdc6c4dad60c49084e61b55d42aa97" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":105159904,"asset_id":105788844,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/105159904/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="105788844"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="105788844"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 105788844;

En este trabajo se presentan los resultados de las actividades de prospección y excavación desarrolladas. Como resultado de las mismas, se identificaron 11 áreas en las que los materiales arqueológicos se presentan en densidades variables y asociados a una matriz sedimentaria con alta proporción de conchillas. En líneas generales, estas se caracterizan por la presencia de material cerámico, lítico, restos óseos humanos y faunísticos, ornamentos, entre otros. A esta información, se integran y discuten los antecedentes para el sector, confirmando el alto potencial arqueológico del área.

La inoculacion con P56 seleccionadas para aumentar la poblacion nativa puede movilizar P a partir de fuentes poco disponibles y por lo tanto mejorar la nutricion de las plantas. El objetivo de este estudio fue evaluar el efecto de la inoculacion sobre las distintas formas de P en suelo, asi como sobre la absorcion de P por las plantas de naranjo (Citrus sinensis) variedad Newhall. La inoculacion evidencio un efecto positivo sobre la nutricion vegetal al incrementar el contenido foliar de P. Este incremento fue mas notable en los ensayos inoculados y fertilizados.

Se seleccionaron tres forestaciones, cada una formada por 12 parcelas y cada parcela, constituida por un árbol dominante. Se midió el diámetro a la altura del pecho (DAP) y la altura de fuste. Se muestreó el suelo a 0-7; 7-30; 30-60; 60-90; 90-120 y&gt;120 cm de profundidad. Se realizaron análisis de pH en agua y en KCl, conductividad eléctrica (CE); Ca2+, Mg2+ y Na+ solubles; y se calculó la Relación de Absorción de Sodio (RAS). Las concentraciones elevadas de la CE se observaron en el horizonte superficial con valores promedios de 1,61 dS m-1, disminuyendo con la profundidad y la RAS en superficie arrojó valores promedios de 5, 92 aumentando en profundidad de 30.

Plant yield, N and P acquisition, mycorrhizal colonisation, rhizobial nodulation and root length were measured and root diameter and root surface area were calculated after two harvests. Species responded differently to specific nutrients when grown pure or mixed. Comparing pure with mixed stands in soils fertilised with P and N + P, L. tenuis showed decreased shoot and particularly root biomass, whereas F. arundinacea showed increases in both biomasses.

El objetivo de este trabajo fue evaluar los cambios que se producen en las formas inorgánicas y orgánicas del P por el agregado de este elemento. Se planteó como hipótesis que en condiciones de suelos altamente meteorizados el P agregado se incorpora en el corto plazo a las formas inorgánicas y orgánicas lábiles; luego de un año pasa a los reservorios más resistentes. Se seleccionaron Alfisoles, Ultisoles y Oxisoles de la provincia de Misiones donde se obtuvieron muestras de los horizontes superficiales para el establecimiento de un ensayo en invernáculo. Se aplicaron tres tratamientos de P con tres repeticiones. Luego de un período de estabilización, se tomaron muestras periódicamente hasta el año, para el análisis de la fracciones de P por el método de Hedley modificado por Sattell y Morris. Las condiciones de incubación, con fluctuaciones en las condiciones de humedad, provocaron incrementos en las fracciones Pi-NaHCO 3 , Pi-NaOH y Po-NaOHus para los tres órdenes, a partir de la disminución, principalmente, del Po-NaHCO 3 y de las fracciones residuales. El fertilizante agregado en los primeros 120 días incrementó las fracciones inorgánicas lábiles y moderadamente lábiles (Pi-NaHCO 3 y Pi-NaOH). A partir de los 60 días, el Pi-NaOHus comenzó a manifestar el efecto de las distintas dosis de P, alcanzando su máximo valor a los 120 días, pasando a partir de ese momento a ser fuente del elemento agregado. El P proveniente del fertilizante, que al principio de la experiencia se ubicaba en las fracciones más lábiles, con el correr del tiempo pasó a formas más resistentes, alcanzando los valores máximos a los 360 días.

The biomass of tomato plants decreased with increasing As concentration in irrigation water, especially tomato berries. In addition, the reduction of biomasses was significantly greater in plants non-fertilized with P. The beneficial effect generated with the P addition indicated that this nutrient played an important role in alleviating As toxicity in tomato plants. The higher the As concentration in irrigation water the higher the As concentration in plant tissues; most of the As absorbed by plants was accumulated in their roots. Phosphorus application has allowed to reduce As translocation toward tomato berries, enhancing plant P status. These observations may be useful for certain areas of the World, in which As-contaminated waters are used for agricultural purposes.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="6e92e464f696f5ae33676f3a2de62108" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":89131775,"asset_id":83947651,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/89131775/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="83947651"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="83947651"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 83947651;

Nutrients cycling is a fundamental component in the functioning of forest ecosystems. Leaves of different forest species observe specific chemical composition, and some seasonal differences in biomass production, may be related to climate fluctuations and/or changes in plant phenology and the variation on nutrient contents. The objective of this study was to analyze the seasonal variability of Fe, Mn, Cu and Zn concentrations in leaves of Gleditsia amorphoides (Ga); Patagonula americana (Pa); Maclura tinctoria (Mt) and Astronium balansae (Ab) from Colonia Benítez Strict Nature Reserve (Chaco, Argentina). The leaves of each forest species were collected monthly, dried at 70ºC and their weight by tree species were recorded. Samples for analytical determinations were prepared by humid oxidation of organic substances from vegetal nets, using oxidant acids such as ternary mixture of HNO 3-H 2 SO 4-HClO 4. After digestion, total micronutrients leaves concentrations were determined by atomic absortion spectrophotometry. Leaves Fe highest values were detected during fall in Mt (76.1mg/kg), Pa (75.2mg/kg), Ab (59.5mg/kg) and Ga (45.3mg/kg). Highest foliar concentrations of Mn were detected in Pa (54.0mg/kg), Ga (50.0mg/kg), Mt (48.0mg/kg), and Ab with the lower Mn concentration (39.7mg/ kg). No significant differences were found for Cu between the different forest species, standing for Pa (11.3mg/ kg), Ga and Mt (11.0mg/kg) and Ab (10.4mg/kg). With regard to leaves Zn, highest concentrations were found in Mt (347.4mg/kg), Ga (319.9mg/kg), Pa (280.2mg/kg) and Ab (255.7mg/kg). Generally, a marked seasonal variation was observed for Mn and Cu concentrations (except in Ga) and Zn (except in Pa), with no statistical differences for Fe. in the species studied, the concentration of micronutrients analyzed showed a marked and erratic seasonal variation, attributed to the relationship established between the native species, and the strong influence of the environment over a long period of time, especially temperature and rainfall.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="2c90a3dee2045ed6430250ac8f7a8932" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":89131772,"asset_id":83947650,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/89131772/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="83947650"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="83947650"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 83947650;

Debido a la variabilidad en la evaluación de la disponibilidad de P en el suelo, se realizó este trabajo con el objetivo de: a) comparar entre sí dos de los métodos más comunes de evaluación de disponibilidad de P del suelo (Bray I y Olsen), y el método de la tirita de papel de filtro embebida en óxido de hierro (Strip); b) estimar cual de los métodos se relaciona mejor con algunas variables vegetales ante distintas condiciones de manejo y tipos de suelos. Se estudiaron suelos de los órdenes Entisol, Alfisol y Vertisol de la provincia de Corrientes en condición natural o cultivado con Citrus, arroz o pasturas, respectivamente. Se determinaron algunas propiedades físicas y químicas, verificando la similitud textural entre los suelos Testigos y Cultivados. Se realizó un ensayo en invernadero de cada uno de los seis suelos con once niveles de P (entre 0-200 mg P por kg de suelo) y luego se los incubó durante 25 días a 28 o C. Al finalizar la incubación se determinó el P disponible mediante los procedimientos recomendados para los métodos de Bray I, Olsen y Strip. Se sembró "rye grass" (Lolium perenne) que se cosechó a los 45 días de la siembra para cuantificar la materia seca aérea y análisis de P en tejido. Los resultados obtenidos en este trabajo sugieren que todos los métodos de evaluación de la disponibilidad de P del suelo describieron de manera adecuada y significativa las relaciones entre MS (R 2 entre 0,35 a 0,95, y valores extremos para el Vertisol y el Entisol), %P (con R 2 entre 0,92 y 0,95) y P absorbido (R 2 entre 0,93 y 0,96 y con muy pocas diferencias entre los suelos) con el P extractado por los tres métodos. Sin embargo, la bondad de los ajustes fue diferente entre suelos, extractantes y manejos productivos, y sugieren la existencia de una interacción tripartita que arroja diferentes resultados en el valor final del P disponible. Se concluye que, no necesariamente el método más sencillo en la evaluación de P disponible para el vegetal es el que mejor refleja la relación con la materia seca o con la concentración del P en el tejido.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="913964dfb81def87fc3d83b7026ba428" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":89131777,"asset_id":83947647,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/89131777/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="83947647"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="83947647"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 83947647;

Se seleccionaron tres forestaciones, cada una fonnada por 12 parcelas y cada parcela, constituida por un árbol dominante. Se midió el diá111etro a la altura del pecho (DAP) y la altura de fuste. Se muestreó el suelo a 0-7; 7-30; 30-60; 60-90; 90-120y&gt;120 cm de profundidad.

The objective of the study was to analyze the edaphic properties that may influence the growth and development of reforestation using quebracho (S. balansae) in the Argentine humid Chaco ecoregion. For this purpose, four sites forested with plantations of the same age (years 10-12), similar distance (4 x 4 m2) and health status of S. balansae were selected. In each site, twelve individuals were measured at their diameter at height of chest (DAP) and trunk length (H), and its soil sampled at 0 to - 10; -10 to - 25; -25 to - 55; and - 55 to - 115 cm depth. The following parameters were measured: texture; bulk density (Da); capillary porosity (Pmc); pH; electrical conductivity (CE); soil organic matter (MOS); exchangeable Ca2+, K+ and Na+; and (RAS) sodium adsorption ratio. It is concluded that the edaphic properties conditioning the growth and development of afforestations with quebracho colorado chaqueño are salinity (positively, related to electrical conductivity) and texture (negatively, excess of clay) that would affect the installation and growth of the quebracho colorado chaqueño; even though, concerning depth, an increase in de RAS is preferred, though keeping a moderate salinity.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="f4ae4d8426e923319970e06832b441fc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":77334923,"asset_id":65961083,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/77334923/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="65961083"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="65961083"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 65961083;
