More food and energy allow for more people who then require more food and energy, and
so it has gone for centuries. At the same time, economic progress leads to a different lifestyle …

One of the key issues in manure management of livestock production is to reduce
greenhouse gas (GHG) and air pollutant emissions, which lead to significant environmental …

The largest source of ammonia (NH3) emissions to the atmosphere is NH3 from agriculture,
the majority of which arise from livestock manure. The NH3 emitted is a threat to human …

This work describes a semi-empirical dynamic model for predicting ammonia volatilization
from field-applied slurry. Total volatilization is the sum of first-order transfer from two pools …

Highlights•Infiltration effects are estimated from normalised emission calculations.•A large
manure exposed surface area can counteract fast infiltration.•Band application reduces …

Different technologies can be utilised to mitigate environmentally harmful ammonia (NH 3)
emissions after field application of liquid animal manure (slurry). After a solid-liquid …

Field application of liquid manure contributes substantially to atmospheric ammonia. Low
emission application methods are commonly used to reduce ammonia transfer to the …

Volatilization of ammonia from field-applied animal slurry is a significant problem. Accurate
emission measurements are needed for inventories and research, but are not provided by …

Field application of liquid animal manure (slurry) is a significant source of ammonia (NH 3)
emission to the atmosphere. It is well supported by theory and previous studies that air …

To assess solid-liquid separation as a technology to reduce ammonia (NH 3) emission from
storage and field application of animal slurry, it is necessary to consider a possible higher …
