Transformation of Phosphorus Forms in Paddy Soil as Affected by Organic Fertilizer

摘要

With the gradual popularization of organic agriculture,the phosphorus environment risk caused by applying organic fertilizer is increasingly prominent.The purpose of this article is to study phosphorus forms,which give rise to the eutrophication,under conditions of applying organic fertilizer.Under this conditions,dynamic change characteristics of phosphorus fractionations content were simulated by the method of waterlogged incubation.
