Nutrient, Carbon, and Mass Loss During Composting of Beef Cattle Feedlot Manure
Quantification ofnutrient andmass loss during composting isneeded ωunderstand the composting process, to implement methods for nutrient conservation, andto reduce potential adverse environmental impact. Beef cattle feedlot manure was composted in a windrow on an open concrete area in 1992, 1993, and 1994 to determine the amounts ofnutrient, C, and mass loss during composting. The area was enclo...
متن کاملComposting Unamended Chicken Manure
Normally, manures are composted with amendments. However, a large commercial egg producer in Ohio i s composting unamended chicken manure. Studies were done to characterize this composting, both in situ and in pilot-scale vessels. While overly wet material can hamper initial operation, the general progression dries the material and produces a granular output that is below 20 percent (wet basis)...
متن کاملVeterinary antimicrobials in feedlot manure: dissipation during composting and effects on composting processes.
Composting of manure may lead to the degradation of veterinary antimicrobials, but it is largely unknown if the presence of antimicrobials affects the composting process. Open-air windrow composting of manure from beef cattle (Bos taurus) administered chlortetracycline, sulfamethazine, and tylosin was investigated in a 2-yr study. At windrow construction, chlortetracycline had extensively isome...
متن کاملTemporal Variations of Important Features of Phlogopite Enriched Manure During Composting and Vermicomposting
The production of compost and vermicompost from manure and different organic residues and also, their enrichment with some fertilizers and other treatments have been extensively investigated. However, no study has yet been conducted on the enrichment of composted and vermicomposted manure with clay minerals. This research was, therefore, carried out to investigate the selected properties of phl...
متن کاملSpeciation of heavy metals during co-composting of livestock manure
Heavy metals determination in manures provides benefi cial information to predict the availability and the potential contamination of environment. Therefore, a study was carried out to investigate heavy metals changes in livestock manure during a co-composting process. The metals were stepwise fractionated into exchangeable, adsorbed, organically bound, carbonate precipitated and residual forms...
