The Issue on Organic Manure in Developing Modern Agriculture in China

In this paper, the author discussed four major issues on the use of organic manure(OM) in developing modern agriculture in the context of main chemical fertilizer applications in China. The issues are as follows: (1) Total amount of the OM used and its quality. The total amount of OM resources were about four billion tons, but their general quality as lower in recent years; (2) Industrialization and commercialization of the OM. Some problems such as quality and price of products, producing equipments and processing and so on should be solved; (3)Mineralization and humification of the OM. It should pay enough attention to promote OM to play both roles for supplying mineral nutrients and improving soil of the humic products; (4) Scientific and efficient use of the OM.
