土壤化学是研究土壤的化学组成和化学变化的科学。土壤是地壳的最外层组成部分,它的化学性质既遵守一般的地球化学规律,又受到植物的强烈影响,而且又常常根据人类的需要在一定程度上被定向控制,所以土壤化学作为应用化学的一部分,它的内容较为广泛,有人说土镶化学是化学中最复杂的一个学科分支。 Soil chemistry is a science that studies the chemical composition and chemistry of soils. Soil is the outermost component of the crust, its chemical properties not only follow the general laws of geochemistry, are strongly affected by plants, and are often directed to human needs to a certain extent, so the soil chemistry as applied chemistry Part of it, its content is more extensive, some people say soil chemistry is the chemical branch of the most complex discipline.
