Abstract:Commercial organic fertilizer is an effective way to promote resource utilization of livestock manure through the marketbased operation mode.Based on the combination of field investigation,literature researches and data from statistical yearbook,productive potential and demand for commercial organic fertilizer were computed.Surplus ratio was introduced to quantify the match degree of productive potential with the demand of all the crops planting and with the demand of vegetable,fruit and tea planting.Development arrangement for commercial organic fertilizer was discussed based on surplus ratio.The result shows that productive potential was less than the demand of all crops planting and exceeded that of vegetable,fruit and tea planting in the whole country.The surplus ratio varied greatly among provinces in China.Combined with both surplus ratio and manure amount in each province,the country was divided into three regions like the development zone of commercial organic fertilizer,energetical development zone and moderate development zone respectively.Suggestions for commercial organic fertilizer development were proposed for each zone,which provided reference for the promotion of livestock manure resource utilization in China.
