Outline of Final Research Achievements

The purpose of this study is to establish a fertilization system and soil management techniques that can be recommended by both the growth aspects and the environmental aspects of the soil of the fruit trees. First, it was carried out soil surveys in apple orchards of coarse gray lowland soil in Aomori prefecture. It was then carried out physicochemical tests of samples taken in order to perform numerical analysis. Finally, embedded in the soil sensor in the depth 10,50,100cm of apple orchards, was monitoring the volumetric water content, the electrical conductivity and soil temperature over a period of one year and eight months. From the results of numerical analysis, if it can continue to maintain the yield and quality of apples by not fertilizing the amount of nitrogen fertilizer, which is defined in the fertilization criteria, it was suggested that it is possible to protect the groundwater environmental standards.
