However, increasing chemical fertilizers not only contributes to food security, but also causes environmental problems such as soil deterioration, greenhouse gas emissions, and water contamination. In addition, Japan is almost entirely dependent on imports for fertilizer. Because fertilizer is essential for food production, it is important to secure fertilizer sources for sustainable agriculture. There are several ways to control the increasing use of chemical fertilizers, such as organic fertilizers, recycling by-products, crop rotation, intercropping. Improvement of crop nutrient efficiency also contributes to chemical fertilizers input. Among various crops, legumes, which fix nitrogen from the atmosphere by biological N2 fixation, have potential to contribute to sustainable crop production. 1. Evaluation of relay intercropping hairy vetch as a green manure to reduce chemical fertilizer input: Producing cash crops and green manure crops during the same growing season is a promising strategy for sustainable crop production. The present study evaluated the relay intercropping of a legume green manure crop (Vicia villosa Roth, hairy vetch) and various crops (broccoli, radish and carrot). The fertilizer effects of hairy vetch incorporation obtained by relay intercropping were compared with those of conventional chemical fertilizer input in subsequent crop production (vegetable soybean and sweet corn). 2. Utilization of soy whey as a fertilizer substitute for agricultural production: soy whey is a by-product of the soy industry. Soy whey includes various nutrients, is expected to be an NPK resource for crop production. Fertilizer effect of single soy whey application or combined application with chemical fertilizer.</p> <p align="center">  </p> <p align="center">  </p> <p align="center"> <img border="0" src="com/25-pckn-SatoshiSoda.png" width="111" height="137"></p> <p align="center"> <b>Satoshi Soda<br> </b><i>Ritsumeikan University, Japan</i></p> <p>Prof. Satoshi Soda was born in Kanagawa Prefecture, Japan in 1972.
