Agricultural operations can pose a threat to the quality of nearby water sources, particularly from nitrogen and phosphorus losses following land application of manure. Biochar application to soils has the potential to ameliorate degraded soils and reduce nutrient leaching to groundwater. The effects of amending sand soil columns with hybrid poplar biochar made by a slow pyrolysis process at 450°C at varying rates (0, 1, 2 and 5% by weight) with repeated dairy manure applications over a 56-week period was examined to evaluate the impact to leachate water quality.
