Cover Crop Effect on Subsequent Wheat Yield in the Central Great Plains

This study was conducted to determine winter wheat yields following both mixtures and single-species plantings of spring-planted cover crops. The study was conducted at Akron, CO, and Sidney, NE, during the 2012–2013 and 2013–2014 wheat growing seasons under both rainfed and irrigated conditions.

Cover crops and organic mulches for nematode, weed and plant health management

Traditional cover cropping systems for nematode management seldom consider weed and soil nutrient management concurrently. Integrating cover crops suppressive to plant-parasitic nematodes with a cover crop mulching system could improve traditional approaches. Two field experiments were conducted in 2003 and 2004 to evaluate ‘Tropic Sun’ sunn hemp (Crotalaria juncea) and ‘Iron Clay’ cowpea (Vigna unguiculata) […]

Cover Crop Biomass Harvest Influences Cotton Nitrogen Utilization and Productivity

There is a potential in the southeastern US to harvest winter cover crops from cotton (Gossypium hirsutum L.) fields for biofuels or animal feed use, but this could impact yields and nitrogen (N) fertilizer response. An experiment was established to examine rye(Secale cereale L.) residue management (RM) and N rates on cotton productivity. Three RM […]

Cover Crop and Plastic Mulch Integration into Vegetable Production (Headland AL)

This project examined the effects of three winter cover crop species grown singly and combined in multispecies mixtures on selected biological indicators of soil health and determined the changes of these indicators over a three-year period. The cover crops included single species and mixtures of cereal rye (Secale cereale L.), crimson clover (Trifolium incarnatum L.), […]

Effects of Cover Crop Mixtures on Biological Indicators on Soil Health

Although there is evidence that cover crops enhance soil microbial diversity and activity, limited information is available about the impact of cover crops on biological indicators of soil health. The use of multi-species cover crop mixtures has been promoted nationwide to enhance soil health; however, little data are available demonstrating the benefits of cover crop […]
