| Outline of Final Research Achievements |
This study aims to clarify present condition of Land Conversion between paddy and upland with Plow Tillage ( = LCPT ) which is clearly different from conventional shallow rotary tillage with a relatively large amount of chemical fertilizers, and to clarify conditions that LCPT leads to farming reform through case studies of large-scale paddy farming in Tohoku region of Japan. The following has been suggested.
First, plow often are used in conjunction with large tractor, laser leveler and vertical harrow by large-scale paddy farmers. Second, the productivity improvement of not only rice but also field crops is expected by LCPT. Third, plow tillage after rice harvest is effective as an implementation period. Fourth, it must be able to procure the compost from nearby livestock farmers. Fifth, however efforts of LCPT is still limited because the public subsidies for field crops has large influence to farming, and the agricultural policy is unstable.
