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
The cover crop trials demonstrate the opportunities, benefits and challenges of using cover crops in rotations and as a grazed forage.
Radish (Raphanus sativus) is a great addition to almost any cover crop mix, and NRCS commonly recommends cover crop mixes that include radish as a component. However, radish has many
Brassica green manures have the potential to provide biological control of several common potato pests, including soil borne diseases, nematodes, and weeds. Therefore, a three-year, multidisciplinary study to evaluate pest
Substantial reproduction of Meloidogyne incognita on winter cover crops may lead to damaging populations in a subsequent cotton (Gossypium hirsutum) crop. The amount of population increase during the winter depends
In fall 2000, a non-farm sustainable agricultural research project was established fo rcotton, Gossypium hirsutum L., in Tift County, Georgia. The objective of our 2-yr research project was to determine

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
Two experiments were conducted in north-central Florida to examine the effects of various winter cover crops on plant-parasitic nematode populations through time. In the first experiment, six winter cover crops
In a 3-year field study, population densities of Belonolaimus longicaudatus and other plant-parasitic nematodes and crop yields were compared between potato (Solanum tuberosum) cropping systems where either sorghum-sudangrass (Sorghum bicolor
