日本东方科学技术协力会付会长川濑金次郎在《东技协会报》上撰文,建议中国用钢铁渣生产农业硅质肥料。现摘译如下:土壤是由岩石经风化后、掺杂着动植物的遗体而成的。因此与岩石的成分相类似,其主要成分是氧化硅(SiO_2),并结合有钒土、铁等物质,故把土壤中的无机成分叫作 Kim Jong-ku, president of Japan’s Oriental Science and Technology Association, wrote an article in the East Technical Association Newspaper, suggesting that China use steel slag to produce agricultural siliceous fertilizers. Now the translation is as follows: The soil is made of rock weathered with the remains of animals and plants made of. Therefore, similar to the composition of rock, the main component is silicon oxide (SiO 2), and combined with the material such as bauxite and iron, the inorganic component in the soil is called
