Analyzing the Effect of Livestock Manure Management Policy on the Utilization of Livestock Manure

This study measures the fertilizer value of livestock manure and analyzes the impact of livestock manure management policy on the utilization of livestock manure as a resource. Fertilizer value of livestock manure was estimated using the amount of fertilizer components contained in livestock manure and the price of chemical fertilizer. The effect of the policy on the utilization of livestock manure was estimated using the seemingly unrelated regression technique and the system of linear equations representing the relations between livestock manure utilization and the government financial support(subsidy and loan). The result indicated that the average fertilizer value of livestock manure is about KRW 405 billion per year over the last five years (2013-2017). The increase in the financial support by KRW 100 million increased the amount of livestock manure utilized as a resource by 5,884 tons.
