摘要
Abstract
Soil mineral nitrogen is an important component of soil nitrogen,plays an important role in the transformation of soil nitrogen,and is a major indicator reflecting soil fertility,mainly including nitrate nitrogen and ammonium nitrogen.The accumulation of soil mineral nitrogen is closely related to soil microorganisms,fertilization,temperature,water,tillage and land use.The loss of soil mineral nitrogen may cause the decline of soil fertility,the eutrophication of surface water and the release of nitrous oxide,which will lead to the greenhouse effect and ultimately affect the survival and development of human beings.This paper summarized the composition and source of soil mineral nitrogen,the factors affecting nitrogen mineralization,the extraction and testing of mineral nitrogen,and the impact on the environment,and compared vari-ous testing methods in order to provide a basis for the study of soil mineral nitrogen.关键词
