Fertilizer-heavy agriculture

Japanese: 多肥農業 - たひのうぎょう

Generally, it refers to a farming method that uses large amounts of fertilizer to increase the yield per unit area. In the narrow sense, it refers to a farming method of small-scale farming that aims to increase productivity by increasing the use of large amounts of fertilizer and labor, mainly through bare labor and increased use of fertilizer, especially fast-acting chemical fertilizer. Japanese agriculture before World War II was said to be a typical example. Unlike machinery and land improvement, fertilizer is easy to subdivide investment and has a quick return, so it can be freely adopted by any small-scale farming. Therefore, with the establishment of the chemical industry, especially the ammonium sulfate industry, in the early 1900s, the use of large amounts of fertilizer became a defining feature of Japanese agriculture. However, after the war, even advanced agricultural countries with extensive management began to use large amounts of chemical fertilizer. The so-called Green Revolution also relies on the idea of increasing yields by using large amounts of fertilizer.

一般的には肥料を多量に施して単位面積あたりの収穫量を増大させる農法をいう。狭義にはもっぱら裸の労働と金肥，特に速効性の化学肥料の増投によって生産力の向上をはかる多肥，多労の零細農業経営の農法をさす。第2次世界大戦前の日本農業はその典型といわれた。肥料は機械や土地改良と違い，投資の細分化が容易で，回収も早いため，どんな零細経営にも自由に取入れられる。そのため，1900年代初期の化学工業，特に硫安工業の確立に伴って日本農業の多肥性は決定的な特徴となった。しかし，戦後は粗放経営の先進農業国でも化学肥料が大量に投入されるようになった。いわゆる緑の革命も肥料の多投によって収量をあげることが要諦になっている。
