1. Inter-seeding Cover Crops Influence on Optimal Corn Nitrogen Rate in No-tillMoving from conventional to no-till with the inclusion of cover crops may change the amount and timing of nitrogen (N) provided to corn (Zea mays L.) from mineralization, which may increase or decrease needed N fertilizer to optimize corn grain yield. This study evaluated the effect of cover crop composition on corn N fertilizer requirement and corn grain yield. The effect of three cover crop treatments (no cover crop, single grass species, and grass/broadleaf mixture) on corn... J. Clark, S. Osborne, P. Kovacs, R. Slaght |
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...

3. Impact of Phosphorus Soil Test Level Differences on Crop Response in No-till Soils in Central South DakotaWater and nutrient dynamics in no-till soils vary significantly from conventionally tilled soils. It is evident that soil structure, chemical parameters, and biological profiles influence the functionality of these different management systems. University soil fertility programs have been developed and calibrated for conventionally tilled management. Dakota Lakes Research Farm (Pierre, SD) conducted five years of research (2018-2022) to investigate the impact of phosphorus soil test levels in... S. Ireland, J. Clark |
