Corn stover harvest and tillage impacts on near-surface soil physical quality

Excessive harvest of corn (Zea mays L.) stover for ethanol production has raised concerns regarding negative consequences on soil physical quality. Our objective was to quantify the impact of two tillage practices and three levels of corn stover harvest on near-surface soil physical quality through the Least Limiting Water Range (LLWR). We evaluated no harvest, moderate and high stover harvest ...

Fluid Fertilizer’s Role In Sustaining Soils Used For Bio-Fuels Production

The shortand long-term effects on soil nutrient cycling, physical properties, and biological activity of striving for higher grain yields and removing crop residues for bio-fuels production must be understood to provide more quantitative crop and soil management guidelines. This study focuses primarily on potassium (K) and sulfur (S) response by corn (Zea mays L.) grown for bio-energy feedstock...

Corn-Residue Transformations into Root and Soil Carbon as Related to Nitrogen, Tillage, and Stover Management

Recent studies of SOC storage and turnover have employed 13C natural abundance ( 13C) as an in situ Soil organic carbon (SOC) is sensitive to management of tillage, marker of relic and recent SOC pools. Mass concentraresidue (stover) harvest, and N fertilization in corn (Zea mays L.), tions of SOC and the 13C signature are sufficient to but little is known about associated root biomass includin...

Characterization of Soil Amended with the By-Product of Corn Stover Fermentation

Corn stover harvested for ethanol production reduces the amount of residue returned to the soil. Crop residues Corn (Zea mays L.) stover is a potential biofuel; however, removing on the soil surface are important in controlling wind this stover from the land may increase the risk of erosion and reduce soil organic matter (SOM). Land application of corn stover fermentaand water erosion (Lindstro...

تأثیر سیستم‌های خاک‌ورزی و کود آلی بر مقاومت فروروی خاک تحت کشت ذرت

Tillage systems and organic manures could affect soil physical and mechanical properties. This study was conducted to investigate the impacts of two tillage systems including conventional tillage by moldboard plowing (plowing depth, 30 cm) and reduced tillage by disk plow (plowing depth, 15 cm) and three rates (0, 30 and 60 ton ha-1) of farmyard manure (FYM) on the soil penetration resistance u...
