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 …

Residue, tillage, and nitrogen effects on soils
Harvesting corn (Zea mays L.) residue for use as a biofuel feedstock may alter important chemical and physical properties of soils. Coupled with the common management practices of nitrogen fertilizer application and tillage, this practice could lower soil organic carbon (SOC), as well as increase …

Crop residue management effects on crop production, greenhouse gases emissions, and soil quality in the Mid-Atlantic USA
… stover and wheat straw (Triticum aestivum L.) residues have particular promise given these crops are widely grown and their cellulosic fractions present a captured resource as a co-product of grain production. Annual systems also offer the ability to change crops rapidly in response to changing …

Managing Continuous Corn for Yield and Soil Productivity
… time of soil sampling should be the same. Corn residue remaining after grain harvest may be used for ethanol production in the future, and corn residue may preferentially be harvested from fields where corn is grown continuously. Field experiments were conducted in Illinois to determine how …

Impacts of Crop Residue and Cover Crops on Soil Hydrological Properties, Soil Water Storage and Water Use Efficiency of Soybean Crop
<p>Cover crops and crop residue play a multifunctional role in improving soil hydrological properties, soil water storage and water use efficiency (WUE). This study was conducted to better understand the role of crop residue and cover crop on soil properties and soil water dynamics. The study was …

Effect of Alternative Management Practices and the Fungal Endophyte (Epichloë festucae var. lolii) on Improving the Longevity of Perennial Ryegrass (Lolium perenne L.) in Minnesota
… alternative management options, including fall residue management strategies and plant growth regulator applications, for multi-year seed production of perennial ryegrass. Our findings suggest that fall residue management, including both field burning and mechanical residue removal, was critical …

A Comparative Analysis of Sorghum and Maize as Bioenergy Feedstock for the US Midwest: Compositional Attributes and System Nitrogen Dynamics
… of system N balance, specifically focused on N removal in harvested tissue and N loss to subsurface drainage water, was conducted at Purdue University’s Water Quality Field Station. The study compared continuous residue removal systems of sorghum and maize to grain-only maize-based systems, two …

LAND USE LEGACY REGULATES MICROBIAL COMMUNITY STRUCTURE AND FUNCTION IN TRANSPLANTED CHERNOZEMS
… main and subplot factors, respectively and crop residues were removed annually at harvest. A 2012 survey of soil microbial abundance and community structure revealed distinct communities among 10 different soil types, indicating a persistent legacy effect of previous land use, irrespective of the …

Legume integration and nutrient management impacts on soil health and cropping system productivity
… 1) integration of different legume species and residue retention on nitrogen fixation, soil health and carry-over benefits for subsequent crops, 2) distinct nutrient management strategies on soil health, crop performance and system profitability and 3) residue C input and soil N availability in …
