For more efficient utilization of agricultural organic waste composts, this research formulates the demand of agricultural organic waste composts and the supply of compost converted from agricultural organic waste in the region, and models the demand-supply balance of agricultural organic waste compost in some regions. Objects of study include 6 urban districts, 5 county-level cities, and 21 counties in northern Henan Province, China. The crops’ latent demand for compost and the latent supply of compost converted from agricultural organic wastes (straw and livestock manure) in each region is computed for an analysis of demand-supply balance. According to the findings, there is a large deviation in both the ratio of the supply of livestock manure composts to that of straw composts and the demand-supply ratio of composts in the studied regions. To be specific, the overall demand-supply ratio in the studied regions is about 1.21, showing that demand is greater than supply. Theoretically, all agricultural organic wastes can be used for agricultural production in these regions. In addition, actual demand ratio (actual demand/ latent demand) is found in the utilization of composts. Supposing the actual demand ratio is 50%, research again analyzes the demand-supply balance, revealing that all livestock manure composts can be utilized, but that straw compost is surplus in large amounts in the studied regions.
