一系列应用科学(土壤学、农业化学、作物裁培学等)的实践导向和一系列相邻学科(地理学、地球化学、生物化学等)的理论探讨,在其发展的一定阶段,由于将农用土地作为共同的研究对象而异途同归,造就了一个新的科学方向——农业地球化学的产生。农业地球化学的基础是 A series of practical guidance of applied science (soil science, agricultural chemistry, crop cultivation, etc.) and theoretical discussions on a series of adjacent disciplines (geography, geochemistry, biochemistry, etc.) Agricultural land as a common object of study and different from each other, creating a new scientific direction - agricultural geochemistry. The basis of agricultural geochemistry is
