研究内容从广义的角度说,土壤化学是研究土壤的化学组成和化学性质及其变化的科学。但是在土壤化学发展的不同阶段,研究的主要内容有很大不同。第二次世界大战以后,特别是六十年代以后,由于土壤矿物学渐成为一个独立的学科分支,而且土壤肥力学(中国称为“农业化学”)和土壤发生学等研究中广泛使用化学方法,所以土壤化学已经以研究土壤化学性质的基本规律,即土壤物理化学性质为主。在这方面,土壤胶体表面的化学受到较多的注意。1982年第十二届国际土壤会议决定在土壤化学委员会之下设立一个“土壤胶体表面”专业
Research Content From a broad perspective, soil chemistry is a science that studies the chemical composition and chemistry of soils and their changes. However, at different stages of soil chemistry development, the main contents of the study are quite different. Since the Second World War, especially after the 1960s, soil mineralogy has gradually become an independent branch of science, and chemical methods have been widely used in such studies as soil fertility (called “agrochemicals” in China) and soil genesis , So soil chemistry has been to study the basic laws of soil chemistry, namely the physical and chemical properties of soil. In this respect, the chemistry of soil colloids is receiving more attention. The Twelfth International Soil Conference in 1982 decided to establish a “soil colloidal surface” under the Soil Chemistry Committee
