摘要:We determined the value of soil test information for potassium (K) in upland cotton productionusing the linear response plateau (LRP) and linear response stochastic plateau (LRSP) functions. Astochastic dynamic programming model was used to determine the net present value to K fertilizerwhen optimal K was applied with knowledge about K carryover. Using K carryover informationfor K application decisions increased net present value and helped maintain steady levels of soilK. The LRSP function fit the data better than the LRP, and the value of soil testing was $27 ha1lower over ten years using the LRSP.
