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

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
