1. Inter-seeding Cover Crops Influence on Optimal Corn Nitrogen Rate in No-till Moving 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 Download paper
2. Impact of Phosphorus Soil Test Level Differences on Crop Response in No-till Soils in Central South Dakota Water 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 Download paper
