摘要

Cotton is a high-value crop that requires the extensive use of costly fertilizers and chemicals. This paper provides a synthesis of the literature on the economics of fertilizer management in U.S. cotton production. The review identifies several production factors and nutrient application strategies based on published research including: 1) economically optimal N, P, and K management as affected by cotton lint and input prices, tillage practices, row-spacing, winter cover crops, and production risk (yield variability); 2) the trends in the adoption of precision farming technology to improve the efficiency of fertilizer and lime application in cotton production; and 3) the profitability of using precision technology for N, P, and K nutrient management in cotton production. Studies from peer-reviewed journals, Proceedings of the Annual Beltwide Cotton Conferences, and university publications were used to summarize current knowledge and suggest future avenues of research.
