1) We investigated the changes of soil condition induced by the crop rotation (paddy for 4 years and following one year for a barley-soybean) in the paddy field, and we also investigated the farmers' correspondence on the method of fertile management, with the changes of soil.2) We carried out this investigation in 1988, on the fields of "OKISHINPO Farming Group" which was the typical model of paddy Farming Group, located in Shirone, Niigata.3) Most of the farmers controled the nitrogen fertilizer on quantity and the method of split apprication, according to the changes of soil estimated experientially. They obtained the high yield of rice HIMENOMOCHI; 506-638kg/10a.4) It is necessary for succesful cultivation of KOSHIHIKARI and increase of the yield of upaland crops, to understand the patterns of soil nitrogen mineralization of rotated paddy soils.
