Improvement of petroleum hydrocarbon remediation using the oat plant in the soil treated by poultry manure
This greenhouse experiment aimed to investigate the effects of poultry manure (PM) on the growth of oat plant (Avena sativa) and removal of total petroleum hydrocarbons (TPHs) from soil. The treatments consisted of three TPH levels (4%, 6%, and 8% w/w) and two PM levels (zero and 1%) at three replications. According to the findings, shoot height, number of leaves, and the fresh and dry...

15 صفحه اولEffect of poultry diet on phosphorus in runoff from soils amended with poultry manure and compost.
Phosphorus in runoff from fields where poultry litter is surface-applied is an environmental concern. We investigated the effect of adding phytase and reducing supplemental P in poultry diets and composting poultry manures, with and without Fe and Al amendments, on P in manures, composts, and runoff. We used four diets: normal (no phytase) with 0.4% supplemental P, normal + phytase, phytase + 0...

Nitrous Oxide Loss from Poultry Manure-Amended Soil after Rain
Land application of poultry wastes in Kentucky will increase as the broiler industry grows. If poultry manure stimulates N2O loss from soil it will reduce the fertilizer N value of this waste. In contrast, stimulated NjO loss in grass filter strips receiving the runoff from manured fields could help reduce contamination of surface water by NOf. Our objectives were to determine (i) if poultry ma...
