Soil properties under nitrogen- vs phosphorus-based manure and compost management of corn

Resource use and economic impacts in the transition from small confinement to pasture-based dairies

Compares the farm performance and economic impacts of five representative dairy farms in Michigan transitioning from conventional confinement to seasonal- and pasture-based systems, and evaluates the potential for integration of an anaerobic digester in the confinement and seasonal pasture systems. Results show confinement systems had higher milk production per kilogram of feed, followed by the seasonal pasture and the annual pasture systems. But the annual pasture-based system had the greatest net economic return to management and unpaid factors followed by the seasonal pasture and confinement systems.

Life Cycle and Economic Assessment of Anaerobic Co-digestion of Dairy Manure and Food Waste

A comprehensive life cycle and financial analysis shows anaerobic co-digestion of dairy manure and food wastes is a preferable solution for waste management and bioenergy production in terms of environmental and economic performance when compared to a control system that anaerobically digests dairy manure but landfills food wastes.

Replacing Commercial Sidedress Nitrogen with Liquid Livestock Manure on Emerged Corn

Livestock producers can more fully utilize the nutrients in livestock manure to reduce purchased fertilizer costs if they can apply manure when crops need the nutrients.

From waste-to-worth: energy, emissions, and nutrient implications of manure processing pathways

Four manure processing pathways are evaluated to provide a system-level understanding of their impacts on different sustainability indicators. In particular we look at how solid-liquid separation, anaerobic digestion, and AD+SLS affect depletion of fossil fuels, nutrient balances, global warming potential, and ammonia emissions when compared to the base-case pathway of direct land application.
