论述了中国土壤质量和农作物优质高产与土壤环境中化学元素N、P、K、S、Fe、Mn、Cu、Zn、B、Mo、V、Sr、Ti、Mg、La、Ce、Pr、Nd、Sm、Eu、Y、Gd、Tb、Dy、Ho、Er、Tm、Yb、Lu、Ga、Co、Ni、F、Tl、Si、Na、Cr、Pb、Cd、Hg、Se、Ba、Te、Ta及有机质、酸碱度、含水量、含盐量有密切的关系。提出了农业地质研究的目的、内容、方法及管理。
The quality of soil and high grade and yield of crops are related nearly with soil chemical elements,there are 37 kinds of useful elements of N,P,K and so on,7 kinds of baneful elements of Cr,Pb,Cd,Hg,Ba,Ta,Te,organic matters,water content and salt content as well as pH values in soil environment in China. According to the distribution and content of soil elements and their qualities in China,the aims,contents,methods and management of geo-agriculture study are put forward,including quality investigation of soil resources,study and development program of soil resources,organization and management for the investigation of geo-agriculture at government levels.
