Optimizing Nitrogen Use in Cotton Production
MetadataShow full item record
This paper presents a dynamic optimization model used to derive nitrogen fertilizer optimal decision rules for irrigated cotton production in the Southern High Plains of Texas. Components of the dynamic optimization model used in this study uses both experimental and simulated data. Results indicate that dynamic optimal nitrogen applications critically depend on initial nitrate-nitrogen levels and cotton and nitrogen prices. It is shown that the adoption of the nitrogen optimal decision rules could help to improve the cash-flow situation of agricultural producers and would contribute to improve water quality in the Southern High Plains of Texas.
