Effect of cattle slurry separation on greenhouse gas and Ammonia emissions during storage
Storage of cattle slurry leads to emissions of methane (CH4), nitrous oxide (N2O), ammonia (NH3), and carbon dioxide (CO2). On dairy farms, winter is the most critical period in terms of slurry storage due to cattle housing and slurry field application prohibition. Slurry treatment by separation results in reduced slurry dry matter content and has considerable potential to reduce gaseous ...

Feeding willow to ruminants could reduce greenhouse gas and ammonia emissions - Case Study
Trees provide shelter and shade for livestock, and some offer additional forage, nutritionally important supplementary minerals, and possible control of intestinal worms through the action of condensed tannins contained within the leaves. Condensed tannins also have the potential to suppress microbial activity in the rumen, reducing the uptake of nitrogen into the blood, and ultimately into the ...

Pilot scale facility to determine gaseous emissions from livestock slurry during storage
Livestock production is a growing source of air pollution, locally and to the wider environment. Improved livestock manure management has the potential to reduce environmental impacts, but there is a need for methodologies to precisely quantify emissions. This paper describes and evaluates a novel storage facility for livestock slurry consisting of eight 6.5-m3 cylindrical units. The stores may ...

Enhancing soil infiltration reduces gaseous emissions and improves n uptake from applied dairy slurry
Rapid infiltration of liquid manure into the soil reduces emissions of ammonia (NH3) into the atmosphere. This study was undertaken to assess the effects of two low-cost methods of assisting infiltration of applied dairy slurry on emissions of NH3, nitrous oxide (N2O), and on crop N uptake. The two methods were removing of solids by settling-decantation to make the manure less viscous and ...

Effect of N-(n-butyl) Thiophosphoric Triamide and 3,4 Dimethylpyrazole Phosphate on gaseous emissions from grasslands under different soil water contents
The intensification of grassland systems is leading to serious environmental risks due to the large input of nitrogen (N) in fertilizers and the subsequent gaseous losses. Addition of nitrification inhibitors (NI) or urease activity inhibitors to fertilizers could reduce these losses to the atmosphere. In the present study, the effects of the nitrification inhibitor 3,4-dimethylpyrazole phosphate ...

Introducing the technique of composting in a rural municipality in Chile
Waste management in Chile Until a few years ago there had been a lack in the supply of basic infrastructure needs like the supply of drinking water, sewage systems, electricity and communication in a lot of rural areas in Chile. With the advancing economic development further necessities have arisen. New objectives are the extended development of infrastructure, the conservation of natural ...

An integrated perspective on assessing agricultural air quality
The biogeochemical cycling of trace gases (e.g. nitrogen, sulphur, etc.), and contaminants on local, regional, and global scales is a complex system of emissions, transformations, transport, and deposition. To date, limited, if any, attempt has been made on quantifying and identifying direct emissions of gaseous sulphur compounds from agricultural operations. This represents a major regulatory ...
