IV. Showa Era (FY21-FY63)<\/h3>\n\n\n\n

\u3000The national average yield from the first to the 20th year of the Showa Era was 300 kg\/tract, almost the same level as the 290 kg\/tract during the Taisho Era (1912-1926). In addition to weather disasters such as cold damage, shortages of production materials such as fertilizers are thought to have been a major factor.<\/p>\n\n\n\n

\u3000In addition to variety and fertilizer tests, in FY2013, five years after the end of the war, a fertility test was conducted to clarify the relationship between weather and paddy rice growth, and technical information on growth was provided, which was considerably enhanced compared to the prewar period. In addition, the company has improved seedling cultivation methods by conducting comparative tests of heat-retaining eclectic nurseries and normal nurseries, and has conducted detailed surveys of urea fertilizer, ammonium sulfate, and potassium chloride as well as other methods of ear fertilization.<\/p>\n\n\n\n

\u3000The idea of using potassium chloride solution to measure pH came from Gintaro Daikubara, who was the first in the world to research methods of improving soil acidity. He believed that soil acidification adversely affects crops because of aluminum ions dissolved in soil moisture (soil solution), and that the degree of adverse effect is determined by the amount of exchangeable aluminum retained in the soil. As a method to measure this, he devised an ion-exchange method in which the exchangeable aluminum retained in the soil was ion-exchanged with potassium ions in a potassium chloride solution and released into the solution.<\/p>\n\n\n\n
