Interpretive Summary: Conservation tillage has significant potential as a management tool for cotton production on sandy soils that are drought-prone and susceptible to erosion. Minimizing soil disturbance can reduce irrigation requirements and runoff, which in turn reduces the transport of sediment, nutrients, pesticides, and other agrichemical residues into surface waters. While potential benefits of conservation tillage are widely recognized, actual benefits in terms of water conservation and quality vary considerably, depending on numerous factors including soil characteristics, topography, pest pressure, agrichemical use, and weather. To better characterize some of these differences, a collaborative research effort was established to systematically evaluate impacts of strip-tillage on water quantity and off- site water quality. Strip-till was found to conserve soil water while reducing runoff and sediment transport when compared to conventional-till. These results should be of interest to growers and water managers who are concerned with optimizing water use to lower production costs while protecting water quality.
