New Stage of Agricultural Mechanization Research in Japan

摘要

Three topics are mentioned in the paper; new responsibility of agriculture, a stage of technology package, and a process of decision making. The land use strategy should be changed under the serious food crisis; that is, production increase could not catch up with increase in demand during the last decade. All farm land, even house gardens, began to have responsibility to meet the demand of food supply. Even the city governments in Japan started to combat against the food crisis in 2009. Precision agriculture reaches a new stage of technology package, and this provides a new avenue to innovate farm management for any style of agriculture. A combination of the real-time soil spectrophotom-eter and a combine harvester with a yield monitor, for example, creates an environmental impact map of missing nitrogen. A model for the decision making process redefines by four learning phases and creates eleven process units of thinking from which a thinking process can be described for weed control practice as a case study.
