Enhancing hydraulic performance of a multi-stage anaerobic digester for high solids cattle manure
… applied to high solids substrate such as dry-lot cattle manure. In Colorado and the rest of the arid west, feedlot practices and dry climate combine to form a waste product that is very high in total solids (TS) content, from 50% up to 90% TS. Since the most common conventional digestion practices …

SOIL PHOSPHORUS AND NITROGEN EXPORT AND RETENTION IN RAINFALL RUN-OFF FROM MANURED LANDSCAPES
Rainfall run-off from manured agricultural fields can be high in nitrogen (N) and phosphorus (P) due to excess nutrient application that is unused by crops. This can pose the risk of eutrophication of nearby surface water bodies receiving run-off. The objective of this study was to determine the …

Soil conditions and early crop growth after repeated manure applications
Development of the swine and cattle industries has led to an increase of manure application to agricultural lands in Saskatchewan. Studies have been conducted to determine the nutrient benefits of swine manure application. However, a need was also identified for information on the effects of manure …
