Cover crops are typically sown between cash crops and can suppress weed emergence and growth. If cover crops are sown after cash crop harvest the system is left susceptible to
Weed control is important to optimize crop production. This study was conducted to compare the effectiveness of different methods of fall-implemented weed control strategies. These strategies included different cover crop
Cover crops offer many potential benefits to crop production. They diversify the plant system, increase soil organic matter, and reduce erosion. However, they can be expensive to plant. By grazing
Agriculture in Kansas and the Great Plains faces many sustainability challenges. Cover cropping is a practice that can affect sustainability by improving soil health parameters in some environments, but more
This study aimed to (i) determine the long-term effects of no-till with CCs and varying nitrogen (N)rates on subsequent sorghum [Sorghum bicolor (L.) Moench] yield and yield components, (ii) assess
Cover crops have numerous benefits and while cover crops have been used for centuries, currently there are few producers in Kansas growing them, so there is a need for additional
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
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
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
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
