Corn residue, tillage, and row spacing effects on soybean
Most soybeans [Glycine max (L.) Merr.] follow corn (Zea mays L.) in the US corn belt, and soybean seed is often planted without tillage into standing corn residue or, if tilled, into a considerable amount of corn residue left on or near the surface. The increase in corn residue with increasing corn …

The Contribution of Within-Field Inoculum Sources of Gibberella zeae to Fusarium Head Blight in Winter Wheat and Barley
… graminearum), the causal agent of the disease. Corn residues are considered to be primary sources of inoculum for epidemics of FHB. Therefore, knowledge of the movement of Gibberella zeae from a local source of infested corn residue is critical to the management of FHB in wheat and barley. …

Managing Continuous Corn for Yield and Soil Productivity
With recent transition from the corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] (CS) rotation to continuous corn (CC) in the Midwestern U.S., there is a need to understand how this transition will affect soil organic matter (SOM). Soil samples were collected following corn from three locations …

Stenocarpella Maydis: Identification, Management, and Population Diversity
<p>Diplodia ear rot (DER) has been a persistent corn disease across the Midwest, and in recent years it has become an annual problem. The objectives of this study were to i) develop a molecular assay for the identification of Stenocarpella maydis, causal agent of DER, ii) evaluate the effect of …

Corn planting strategies in the United States Corn Belt
In Illinois, corn (Zea mays L.) producers aim to start planting operations in mid-April. Early planting allows for the use of longer-season corn varieties, which tend to yield more than shorter-season varieties. However, constraints to early planting in the U.S. Corn Belt include excessive soil …

Feeding the soil to feed the planet: soil health outcomes from novel amendments to residue management
… derived from cheese manufacturing as well as corn residue management in semi-arid agroecosystems. Both the novel soil amendment and corn residue management approaches were established with the goal of conserving soil water in these water limited systems. The novel soil amendment approach …

Goss’s wilt and leaf blight of corn: chemical control, residue management and resistance
Goss’s wilt and leaf blight of corn has been a re-emerging disease in the United States. Caused by the bacterium Clavibacter michiganensis subsp. nebraskensis (Cmn), Goss’s wilt has been increasing in Illinois due to factors that include continuous maize rotations, reduced tillage which increases …

Yield response of continuous corn to residue removal, tillage, and nitrogen rate
Removing corn residue for use as biofuel may require adjustments in tillage systems and nitrogen rates. Research was conducted at DeKalb, Monmouth, Urbana, and Perry, Illinois to examine the response of three residue removal rates (full, partial, and none) and two tillage treatments (no-till and …

Ammonia Volatilization, Urea Hydrolysis, and Urease Inhibition with the Application of Granular Urea in Agroecosystems
… 2) determine if urease can be extracted from corn and soybean residues; 3) determine if differences in urease activity are present in corn and soybean residues; and 4) evaluate N content and yield of corn treated with surface-applied coated urea fertilizers. The laboratory ammonia …

Agronomic assessment of grazing method of corn residues on cow performance, residue utilization, crop yield, and soil properties
… to evaluate the effects of beef cows grazing corn residues on cow performance, residue utilization, subsequent crop yield, and soil physical and chemical properties. Two grazing methods (strip grazing, (SG) and continuous grazing, (CG)) and a control (ungrazed, (CT)) were arranged in a …

Enhancing the feeding value of corn crop residues to improve beef cattle production
Corn has been used in cattle diets for more the 50 years in the United States. However, since 2005 when the “Ethanol Era” started, the demand for corn to be converted in to ethanol has been increasing. The increased demand for corn to be converted into ethanol, led to increased corn prices. When …

Combining field experiments, modeling, and analytics for integrated crop-livestock system management
… systems in modern agriculture. In the U.S. Corn Belt, tremendous amounts of corn residues left on the land after harvest represent a vast potential nutrition source for beef cattle producers, particularly when farms are specialized in continuous corn operations. Allowing cattle to graze corn …
