Cover crop root contributions to soil carbon in a no-till corn bioenergy cropping system
Crop residues are potential biofuel feedstocks, but residue removal may reduce soil carbon (C). The inclusion of a cover crop in a corn bioenergy system could provide additional biomass, mitigating the negative effects of residue removal by adding to stable soil C pools. In a no-till continuous corn bioenergy system in the northern US Corn Belt, we used CO2 pulse labeling to trace plant C from ...
متن کاملNitrogen source and placement effects on soil nitrous oxide emissions from no-till corn.
A nitrogen (N) source comparison study was conducted to further evaluate the effects of inorganic N source and placement on growing-season and non-crop period soil nitrous oxide (NO). Commercially available controlled-release N fertilizers were evaluated for their potential to reduce NO emissions from a clay loam soil compared with conventionally used granular urea and urea-ammonium nitrate (UA...
متن کاملSoil Organic Carbon Pools After 12 Years in No-Till Dryland Agroecosystems
the slow pool, with decadal turnover times, while 5% of the SOC is found in the rapidly cycling active fraction, Previous studies of no-till management in the Great Plains have with turnover times ranging from hours to months (Folshown that increased cropping intensity increased soil organic carbon (SOC). The objectives of this study were to (i) determine which soil lett, 2001; Shaffer et al., ...
متن کاملCrop Residue Removal and Soil Productivity with No-Till Corn, Sorghum, and Soybean
Crop residues have been considered during the past decade as alternate energy sources to supplement dwindling fossil fuel sources and enhance energy independence in the United States. Agricultural scientists have demonstrated the importance of crop residues in reducing soil erosion, enhancing the soil physical environment for plant growth, and as a reserve for major crop nutrients. In eastern N...
متن کاملLandscape level variation in soil resources and microbial properties in a no-till corn field
Soil microbial properties are known to exhibit high spatial and temporal variability, which can hinder our understanding of the effects of agricultural management on soil microbial activities, populations and communities. However, if this variability is explicitly considered in soil sampling schemes, experimental results can help us better understand soil microbial properties. In this initial a...
