Cotton Response to Chelated Fertilizer Formulations in a Semi-Arid Environment

A newly released in furrow fertilizer additive, Levesol, exclusively from West Central is a ortho-ortho EDDHA chelating agent used to increase the uptake of micronutrients such as zine, iron, copper, and manganese  by preventing the binding of phosphorus and keeping micronutrients in soluble form. This chelating agent is found in other West Central proprietary products, Soygreen and Redline. A first year on producer farm study was conducted in Anton, Texas to observe crop response to the in furrow additions and their impacts on boll retention, plant tissue analysis and lint yield. In this study, we had five treatments: control (water), Redline at 3gal/A + 2gal H₂O/A, Levesol at 1.5gal/A + 4.5gal H₂O/A, Soygreen at 0.7gal/A + 3gal H₂O/A, and Soygreen at 0.3gal/A + 4gal H₂O/A. It was planted on 1-June at 40,000seeds/A with row lengths being roughly 1,500ft and four replications. Discussion will focus on mineral content in plant tissue, boll retention, yield, and soil nutrient availability.
