1. Does Coal Char Reduce Ammonia Volatilization by Slowing Urea Hydrolysis in Soil? Ammonia volatilization due to urea hydrolysis begins immediately after N fertilizer applied in soil and continues up to two weeks. This process might adversely affect N availability in soil/ plant systems and reduce soil fertility and crop yields, as well as bring the negative impact in environment. Char, incomplete burning of coal combustion residue which contains up to 30% total C by weight, is hypothesized to reduce N losses from ammonia volatilization. A 21-day laboratory study was conducted... D. Panday, B. Maharjan
2. Impact of Fertilizer Phosphorus (P) Source, Rate, and Placement Strategy on Yield, Nutrient Uptake, and P Losses in Snowmelt Runoff Water Across Variable Topographies in Saskatchewan, Canada The plant availability and mobility in soil of a fertilizer phosphorus (P) source is influenced by the solubility of the fertilizer product itself as well as the reaction products formed in soil over time. In 2021, 2022 and 2023, responses of wheat, pea and canola yield, P uptake and recovery were determined using eight fertilizer P sources applied in a broadcast and incorporate or side-band placement strategy at a low and high (20 vs 40 kg P2O5 ha-1) rates in...

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.
