简介
Subsurface band application of poultry litter has been shown to reduce the transport of nutrients from fields in surface runoff compared with conventional surface broadcast application. Little research has been conducted to determine the effects of surface broadcast application and subsurface banding of litter on nutrients in leachate. Therefore, a field experiment was conducted to determine the effects of subsurface band application and surface broadcast application of poultry litter on nutrient losses in leachate. Zero‐tension pan and passive capillary fiberglass wick lysimeters were installed in situ 50 cm beneath the soil surface of an established tall fescue (Festuca arundinacea Schreb.) pasture on a sandy loam soil. The treatments were surface broadcast and subsurface‐banded poultry litter at 5 Mg ha−1 and an unfertilized control. Results of the rainfall simulations showed that the concentrations of PO4–P and …
