Evaluation of Nutrient Availability from Swine Manure
To utilize swine manure nitrogen (N) to meet the needs of crops and protect water quality it is
critical that we can confidently estimate the availability of the N. While total nutrient content of...
Atmospheric Concentrations, Transport, and Deposition of Ammonia/Ammonium from Large-Scale Swine Production Facilities
Domestic animals are the largest global source of atmospheric ammonia (NH3), with emission rates ranging from 20-35 Tg N yr-1, approximately 40% of natural and anthropogenic emissions combined. (One...
Crop nitrogen and phosphorus utilization following application of slurry from swine fed traditional or low phytate corn diets
Field application of swine (Sus scrofa) slurry provides essential nutrients for crop production. The N to P ratio for slurry is lower than needed by most crops resulting in P accumulation when...
Soil nitrogen and phosphorus availability for field-applied slurry from swine fed traditional and low-phytate corn
Swine (Sus scrofa) slurry contains nutrients essential for crop production but usually contains more P relative to N than is required by most crops, creating the potential for negative environmental...
Soil chemical and microbiological properties in hay production systems: residual effects of contrasting N fertilization of swine lagoon effluent versus ammonium nitrate
This study characterized soil chemical and microbiological properties in hay production systems that received from 0 to 600 kg plant-available N (PAN) ha(-1) year(-1) from either swine lagoon...
Land application of animal manure and phosphorus cycling in soil
Repeated land application of animal manure at rates to satisfy N requirements for crops may increase soil P to levels that cause environmental concern. Biochemical and microbiological parameters are...
Nutrient Removal from swine lagoon liquid by Lemma minor 8627
Nitrogen and phosphorus removal from swine lagoon liquid by growing Lemna minor 8627, a promising duckweed identified in previous studies, was investigated under in vitro and field conditions. The...
Effect of anaerobic digestion on struvite production for nutrient removal from swine waste prior to land application
Swine production facilities are becoming larger in size and are concentrated in smaller geographical areas. Additionally, there is an increasing trend to base manure land application rates on crop...
Utilization of Nutrients in anaerobically-pretreated swine wastewater for greenhouse tomato production
Swine waste treatment in North Carolina typically consists of an anaerobic lagoon and sprayfield upon which crops are grown to utilize the nutrients. Currently, swine lagoon effluent must be applied...
Phosphorus Fractionation in Manure from Swine Fed Traditional and Low-Phytate Corn Diets
Traditional corn (Zea mays L.) (TC), the primary grain used in swine (Sus scrofa) diets, stores a majority of its P as phytate, which is largely unavailable for digestion by nonruminant animals....
Alternatives to minimize the environmental impact of large swine production units
Large swine production facilities have become controversial additions to the agricultural landscape as their numbers and sizes have increased. In addition to being larger enterprises, these units...
