Research overview:
In order to promote continuous agriculture with considering environment, we grasp the transit of farmland fertility and heavy metal content in the soil and analyze its fluctuation element. Effect of long-term application of organic matter and soil improvement fertilizer in representative fields is made clear. Furthermore we make the investigations to establish soil improvement and management technique corresponding to the regional soil type and weather condition, and to establish appropriate application technique of N and P fertilizer corresponding to the soil fertility. As a result of the investigations, a manual in soil and fertilization management with considering environment is made.
