在整个人类历史时期内,积累了许多与土壤化学有关的知识和观察到的现象,虽然这些认识可能仅仅是根据一些尚未十分理解的经验而来的,但其中有许多已在实践中加以利用。这一时期可看作是土壤化学的史前期。土壤化学作为一门独立学科,是在十八世纪末到十九世纪初才开始形成的,这个时期可作为本门学科历史的开始。土壤化学的发展,与当时迅速开展的土壤学和耕作学理论和实验研究中的三个最重要的方面有明显的关系。这三方面的研究是:土壤腐殖质的研究和1876年 Throughout the history of mankind, many soil chemistry-related and observational phenomena have accumulated. Although these understandings may have come merely from some not yet well-understood experience, many of them have been used in practice. This period can be seen as a prehistoric soil chemistry. As an independent discipline, soil chemistry began to take shape only from the end of the eighteenth century to the beginning of the nineteenth century, and this period can serve as the beginning of the history of this discipline. The development of soil chemistry was clearly related to the three most important aspects of the theory and experimental studies of soil science and tillage that were rapidly carried out at that time. The three aspects of the study are: Soil Humus Research and 1876
