A study was conducted in 2014 to examine the short term effects associated with cover cropping systems. The effects of ryegrass, red clover and a cover crop cocktail(mixture of ryegrass,
Replacement of fallow in crop–fallow systems with cover crops (CCs) may improve soil properties. We assessed whether replacing fallow in no-till winter wheat (Triticum aestivum L.)–fallow with winter and spring
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
Farmers reported that in 63 of 70 site-years, properly managed cover crops had little to no negative effect on corn and soybean yield (and actually increased soybean yield in 10
Seeding Technique and Date Effect on Cover Crop Establishment. The highboy seeding technique allows for an early seeding date that resulted in additional cover crop growth when compared to the
Field experiments investigating the effect of cover crops and tillage on muskmelon production and food safety (Iowa State University) and cucumber and acorn squash production (Michigan State University) were conducted.
Soil compaction and lack of fence are often identified by farmers as the two major barriers to grazing cover crops. While soil compaction can reduce crop productivity, issues can be
This was the second year of on-farm research trials designed to evaluate planting corn in 60-in. row-widths for the purpose of improving the success of interseeding cover crops to the
Interseeding cover crops to corn at the V4 stage has gained attention for its potential to foster successful diverse species mixes and generate more biomass than a fall-seeded cover crop.
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
The sandy soils of Muscatine County, Iowa, are prone to erosion and leaching. In the fall, leftover fertilizer applied to the corn and soybean crop is highly susceptible to leaching.
The increase in cover crops across Iowa presents a substantial amount of potential forage available to the beef industry that would otherwise go unutilized. While the benefits of improved soil
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
Cover cropping is a prevalent conservation practice that offers substantial benefits to soil and water quality. However, winter cereal cover crops preceding corn may diminish beneficial rotation effects because two
Cover crops can be a management practice used to improve soil health and increase resilience to extreme climate events in a typical midwestern corn–soybean (Zea mays L.–Glycine max L.) rotation.
Heavy application of nitrogen (N) fertilizers to agroecosystems contributes to water pollution and emission of nitrous oxide (N2O), an atmospheric constituent implicated in the greenhouse effect and stratospheric ozone depletion.
A growing concern of soil health and long-term sustainability has increased interest in no-till and cover crops in the Midwest. Some of the challenges with no-till in the Midwest can
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
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
Field trials were conducted from 2010 to 2013 at four locations in Illinois to evaluate the impact of cover crops (cereal rye [Secale cereal], brown mustard [Brassica juncea], winter canola
