Conventionally managed, continuous monoculture row-crop production has depleted the soil of nutrients, organic matter, and overall productivity. This has increased the need for external inputs, specifcally N, to meet crop
Leguminous cover crops are considered part of sustainable agricultural systems. With the development of no-till crop- ping systems, cover crops have been recognized for their ability to provide N for
The implementation of cover crops in Iowa has the potential to decrease soil erosion, weed density, and nitrate leaching while increasing soil organic carbon. This study investigated nine potential cover
Addition of an overwintering small grain mixed with a frost-seeded legume to corn-soy rotations may reduce N fertilizer requirements and mitigate negative environmental impacts of this cropping system. The small
This thesis contains a comprehensive analysis of research investigating the impacts of nitrogen application timing and cover crops on the biomass production, nitrogen uptake, and cash crop grain yield in
The cover crop trials demonstrate the opportunities, benefits and challenges of using cover crops in rotations and as a grazed forage.
Cover crops may influence soil carbon (C) sequestration and microbial biomass and activities by providing additional residue C to soil. We examined the influence of legume {crimson clover (Trifolium incarnatum
This study assessed the use of cover crops and organic amendments for increasing soil nitrogen for potato production at the Intermountain Research and Extension Center in Tulelake. Researchers evaluated several
Amanda McWhirt, extension fruit and horticulture specialist for the Division of Agriculture, said two major research trials, being held at both the Southwest Research and Extension Center in Hope, and
Leguminous cover crops, which fix nitrogen (N) from the atmosphere and add to the N content of the soil, have the potential to replace or partially replace commercial nitrogen fertilizers.
