标题：AN EVALUATION OF AN ECONOMIC STRATEGY FOR PREVENTING WATER POLLUTION USING A PHOSPHORUS CONSISTENT TRANSPORTATION MODEL: A CASE OF BROILER LITTER MANAGEMENT
摘要：We calculated the profitability of using broiler litter as a source of plant nutrient using a phosphorus consistent litter application rule. We found that each ton of litter can be transferred cost effectively up to 164 miles from the production facilities. The minimum cost phosphorus consistent transportation model developed to meet the nutrient needs of 29 counties in North Alabama revealed that not all the litter can be utilized in the region. The total cost for nutrient supply increased when transportation of litter from heavily surplus counties were prioritized. The effect of chemical fertilizer price change minimally affected the total litter use.
