1. Nutrient Cycling Following Cover Crop Termination in Texas Cotton ProductionCover crop adoption on the Texas High Plains (THP) is severely limited compared to other agricultural regions in the U.S. Cotton producers on the THP consistently site water limitations as the primary reason for not implementing cover crops in their cropping systems. Previous research on the THP has shown that nitrogen immobilization following cover crop termination might be the most leading consequence of cover crops, not water availability. A study was initiated into existing long term... J.A. Burke, K.L. Lewis, J.L. Foster |
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, CanadaThe 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...
