Material Properties in Advances in Organic Fertilizer

摘要

Organic fertilizer is an important material to improve soil physical and chemical properties, to improve soil fertility, crop yield and quality and enhancing crop resistance has a very important role. In recent years, the proportion of organic fertilizer for the Chinese fertilizer gradually decreased reality introduces the connotation and type of organic fertilizer, discusses the following issues: (1) organic fertilizer on soil fertility, including soil nutrients (nitrogen, phosphorus, potassium, trace elements), soil organic matter and structure, soil enzyme activity;(2) the role of organic fertilizer to improve crop yield, quality and disease resistance. At the same time, pointed out the remaining organic fertilizer application in question, and the future development were discussed. Application of organic fertilizer is thousands of years of traditional Chinese agricultural development of the fundamental measures, despite increasing fertilizer use in recent times, but in the case of today's growing emphasis on the human environment, organic fertilizer once again people's attention. Cyclical changes in soil water and heat dynamics of organic fertilizers depend on the date of smaller amplitude, to microbial activity to create a good environment, so that it can pass humification stage, the formation of high fertility and Water Conservation humus to improve soil fertility and crop yield and quality.
