1. Optimizing Nitrogen Inputs in Barley Production in Idaho, Montana, and North Dakota Nitrogen (N) management plays a critical role in balancing yield and malting quality of two-row spring barley (Hordeum vulgare L.) grown in the Northern Great Plains. In 2025, a field experiment was conducted across seven locations in North Dakota, Montana, and Idaho to evaluate the effect of N fertilizer source on barley yield, protein, and kernel plump. Treatments included the commercially available N sources urea, enhanced efficiency urea, urea ammonium nitrate, calcium ammonium... B. Goettl, . Souza, J. Spackman, J. Jensen Download paper
2. 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.
