The Midwest is well known for agriculture, and Iowa is a leader in corn (Zea mays L.) and soybean (Glycine max [L.] Merr.) production. Fertilizers and chemical pesticides used to increase crop production can adversely affect the soil and water health

Nonpoint-source (NPS) pollution is a major cause of surface water quality degradation due to the transport of chemicals, nutrients, and sediments into lakes and streams. Vegetative buffers comprise several effective landscape best management practice

Using x-ray computed tomography (CT) for non-destructive 3-D imaging and analysis of soil physical properties has been investigated for over 30 years. However, applying this system in soil science has remained a specialized research area using primar

Windrow-composted livestock manure has been shown to be less hazardous to the environment compared to manure directly applied to cropland and other agricultural areas. Although offsite contaminant losses through runoff and leaching can occur during t

Livestock grazing in the Midwestern United States can result in significant levels of runoff sediment and nutrient losses to surface water resources. Some of these contaminants can increase stream eutrophication and are suspected of contributing to h

This study quantified the effects of a livestock manure-based windrow compost- ing practice with a fly ash composting pad surface and vegetative filter strip (VFS) buffers on losses of runoff, runoff percent of rainfall, total solids, nitrate-nitroge

This report documents results from a six-year study (1996-2001) that evaluated effects of liquid swine manure application management practices on soil nutrients, organic matter, pH, crop yield; and also discussed water quality implications. Swine man
