Zero tillage in southern Alberta

, : Zero tillage in southern Alberta. Twenty first Annual Alberta Soil Science Workshop Proceedings Farming for the future: 128-136

Zero tillage and conventional tillage systems were compared in both a continuous cropping and crop-fallow rotation at six locations on a range of soil types in southern Alberta. Tillage treatment had little effect on soil moisture conservation or on soil bulk density. Lower yields from chemical fallow at some locations were attributed to lower nitrate nitrogen levels. Yield response to nitrogen fertilizer was greater on no-till plots than on conventionally tilled plots.
