1. Defining Critical Tissue-Potassium Concentrations for Furrow Irrigated Corn Production Potassium (K) is a critical nutrient for adequate corn (Zea mays L.) production, and tissue testing is an essential tool to ensure adequate K nutrition. Despite the important role of K in plant physiological functions, there are no calibrated critical tissue-K concentrations (TKc) for furrow-irrigated corn in Arkansas. This study aimed to define critical TKc values to maximize corn grain yield across different growth stages. From 2022 to 2024, twelve single-site-year and four long-term... J. Silva, G. Drescher, T.

2. Long-term Effects of Cover Cropping and Potassium and Phosphorus Fertilization on Soil Test Results in a Row Crop Production System Potassium (K) and phosphorus (P) availability can be affected by fertilizer inputs and the use of cover crops (CC) through their effects on nutrient cycling. This study aims to evaluate the long-term effects of CC and fertilizer-P and -K applications on soil-test K (STK) and soil-test P (STP) in two long-term field-scale experiments. Field trials were established in 2017 on silt-loam soils at the Lon Mann Cotton Research Station (LMCRS) and at the Rohwer Research Station (RRS), Arkansas. Each... J. Silva, G. Drescher, T.

3. 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.
