Biomass Production with Conservation Practices for Two Iowa Watersheds

Best management practices (BMPs) and cropping systems for mitigating agricultural nonpoint source nutrient pollution include cover crops, and these practices are generally noted for providing a range of environmental benefits. The study aimed to evaluate the water quality implications of vegetation-based conservation practices and biomass production through landscape design at the watershed scale.

Conservation Systems for Positive Net Ecosystem Carbon Balance in Semiarid Drylands

Recent interest in improving soil health has emphasized the need for conservation systems that increase soil organic carbon (SOC) sequestration without negative impacts on crop yield. Cover cropping diversifies cropping systems, lowers soil temperature, and increases SOC sequestration. The goal of this study was to evaluate the SOC dynamics of dryland cropping systems under diverse […]

Cover Crop Effects on Soil Carbon Dioxide Emissions in a Semiarid Cropping System

Cover cropping is increasingly considered in semiarid regions to increase soil organic matter sequestration and improve soil health because of their biomass carbon contribution, soil temperature moderation, moisture conservation, soil aggregation, and aggregate stability. This study was implemented to examine the effect of cover crops on soil carbon dioxide emission in limited irrigation cropping systems […]

Short-Run Net Returns to a Cereal Rye Cover Crop Mix in a Midwest Corn-Soybean Rotation

The potential for cover crops to decrease agricultural nutrient losses and improve soil health has sparked a reemergence of interest in the practice. Though, recent studies have shown that there is a reluctance to adopt cover crops and producers identify matters like familiarity with cover crops, species selection and economic return, or lack thereof, as […]
