Cotton Needs Adequate Phosphorus for Optimum Yields

J. L. Kovar and E. R. Funderburg


Phosphorus (P) is an essential nutrient for cotton. Soil testing and plant analysis are useful for monitoring the P fertility status of a cotton crop. Soil pH is the most important soil property controlling P availability. There is no set method for applying P fertilizer, although band applications can be advantageous in soils with high P fixation potential. Starter fertilizer with P often increases growth and vigor of cotton seedlings; however, yield responses are not predictable.
