Some main problems existent in the present standard for farm products areas of China are discussed in this paper. It is thought that the formulation of a nationwide environment standard for producing areas is not only technically difficult but also likely to give rise to lots of troubles in the course of practical application. Based on the 1:250,000 survey of earth geochemistry of the agro-geological environment in Zhejiang and the study of such affecting factors as the geochemical composition, content and distribution of elements and taking into account the effective quantities of elements that affect people and environment, the authors have formulated the standard of earth environment quality for the unpolluted farm products area in Zhejiang for recommendation. Although there are many factors that affect the quality of farm products, such as atmospheric fallen dusts, irrigative water and fertilizer application, the quality of earth environment in the farm products area obviously plays the most important role.
