英文文献：Incorporation Of Soil Test Results In The Development Of Optimal Long-Term Fertilizer Policies For Farmers
英文文献作者：Stoecker, Arthur L.,Onken, Arthur B.
英文文献摘要：
The economics of using soil test results for making fertilizer recommendations in the presence of nutrient carry-over are discussed. A model for maximizing long run returns with nutrient carry-over is presented. Dynamic programming is used to determine fertilizer applications for grain sorghum given an initial soil test value.
