Manure management: implications for greenhouse gas emissions
Abstract Slurry, farmyard manure and poultry manure are an inevitable consequence of livestock products generated from housed animals. These manures are recycled back to land for plants to use theExpand

Solid—liquid separation of animal slurry in theory and practice. A review
Animal slurry contains plant nutrients that are essential for crop production. However, intensive livestock production may lead to a surplus of plant nutrients on farms and, as a consequence,Expand

A new algorithm to characterize biodegradability of biomass during anaerobic digestion: influence of lignin concentration on methane production potential.
We examined the influence of fibrous fractions of biomass on biochemical methane potential (BMP) with the objective of developing an economical and easy-to-use statistical model to predict BMP, andExpand

Solid-liquid separation of livestock slurry: efficiency and cost.
Abstract Environmental problems may arise on specialized livestock farms, which produce a surplus of nutrients in relation to crop requirements. Separation of this slurry into a liquid fraction and aExpand

Separation efficiency and particle size distribution in relation to manure type and storage conditions.
Mechanical separation of liquid animal manure can be an effective technique for production of a liquid and a nutrient-rich solid fraction. The efficiency of separators depends on the physical andExpand

Nitrogen and organic matter losses during storage of cattle and pig manure
Solid pig manure (240 g kg 1 DM) and solid cattle manure (150-180 g kg 1 DM) were stored in an open storage facility during spring-summer and autumn conditions for periods of 9-14 weeks during 1994Expand

Ammonia, methane, and nitrous oxide emission from pig slurry applied to a pasture in New Zealand.
Much animal manure is being applied to small land areas close to animal confinements, resulting in environmental degradation. This paper reports a study on the emissions of ammonia (NH3), methaneExpand
