Impact of livestock manure and fertilizer application on nitrate contamination of groundwater final report

Abstract

This study examined nitrate leaching out of the root zone and nitrogen supply to corn from two types of manure and from inorganic nitrogen fertilizer. The study took place on a silt loam soil at the Ontario Ministry of Agriculture and Food Research Station, Elora, ON. The soils of this area have developed from a variety of glacial deposits and thus consist of a wide range of textures and drainage classes. The area has been traditionally cropped to corn which is used to supply the increasing amount of livestock operations in the area.
