Ability of yard trimmings compost to mitigate environmental impacts of over-winter field stored poultry litter Milligan, Erica Elaine

Abstract

Incorporation of poultry litter (PL) into crop production on British Columbia's Fraser River delta is an important means of recycling this over-abundant agricultural waste product. However, environmental and ecological concerns associated with overwinter field storage of PL should be addressed. To mitigate these concerns some farmers have been storing the PL on a 30 cm thick base pad of City of Vancouver yard trimmings compost (YTC) and further covering the pile with a 15 cm thick layer of YTC . A column study was conducted on the UBC, Vancouver campus to assess the effects of the YTC base pad and cover on the quality of leachate emanating from the PL. The YTC layer under the PL decreased (P
