PROBLEM TO BE SOLVED: To provide an organic farming in which high-temperature damage or excessive humidification damage to field crops caused by excessive heat of hot water is avoided while a pest control effect by hot water is effectively exerted, which contributes to reduction in labor and cost of farm work, and solution for organic farming used therefor.SOLUTION: An organic farming of the present invention comprises: a farm field maintaining process in which a farm field 10 is maintained by scattering rice bran on passageways 14 around a raising region 12 of field crops in the farm field 10 and laying rice straws 16 on the rice bran a solution creating process in which Natto bacteria, garlic, red pepper, liquors and water that has been used to wash rice are input into water to create solution for organic farming a solution heating process in which the solution for organic farming is heated a farm field solution spraying process in which heated solution for organic farming is sprayed on the farm field 10 and a hot water pest controlling process in which pests are controlled by spraying hot water on the farm field 10.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】温水の過剰な熱に起因する農作物の高温または過湿障害が回避されつつ、温水による防除効果が有効に発揮されることによって、農作業の労力やコストの削減に資する有機農法とそれに用いられる有機農法用溶液を提供する。【解決手段】本発明の有機農法は、圃場10において農作物の育成領域12の周りにある通路14に米ぬかを撒き、米ぬかの上に稲わら16を敷くことによって圃場10を整備する圃場整備工程と、納豆菌、ニンニク、唐辛子、酒類および米の磨ぎ汁を水に投入して有機農法用溶液を生成する溶液生成工程と、有機農法用溶液を加温する溶液加温工程と、この圃場10に対して、加温された有機農法用溶液を散布する圃場溶液散布工程と、この圃場10に対して温水を散布することにより、病虫害を防除する温水防除工程とを備える。【選択図】図2
