1. Season-long Tools for Effective Potassium Management in Arkansas Cotton Production

Knowledge of how accurately soil testing and plant analysis identify nutrient-deficient soils and recommend the proper fertilizer rate is important to ensure farmers are profitable. However, critical tissue-potassium (K) concentrations have not been established for modern high-yielding cotton (Gossypium hirsutum L.) cultivars currently grown across the U.S. cotton belt. Likewise, limited research has investigated the window of opportunity to correct K-deficient cotton with in-season fertilization... G. Drescher, T. Roberts, M. Popp, N. Slaton, M. Ramos do prado, A.
