Soil Amendment Demonstration on Cotton, Greenlee County

Abstract

Boligrow (an aluminum sulfate material from Sweden), gypsum and soil sulfur were evaluated as amendments on soil where differential water uptake had historically been a problem. A crop of cotton was grown and the yield of cotton was taken to determine if an economical change was effected by the amendments. Statistically there was no difference between treatments. A soil analysis indicated that sodium was not a problem in this soil, so texture was probably more related to the differential water uptake problem than was the chemical makeup of the soil.
