Anaerobic digestion is a well-established technology that valorises organic wastes to
produce renewable energy as biogas. The ammonia released during this process can be …

Animal manure consists of predominantly urine and feces, but also may contain bedding
materials, dropped feed, scurf, and other farming wastes. Manure is typically applied to soils …

Manure management at dairy production facilities, including anaerobic digestion (AD) and
solid-liquid separation (SLS), has shown strong potential for the abatement of greenhouse …

National inventories of methane (CH4) emission from manure management are based on
guidelines from the Intergovernmental Panel on Climate Change using country‐specific …

Acidification of slurry is a treatment known to reduce ammonia emissions and it is currently
applied at the farm scale in Denmark by adding concentrated sulfuric acid (H 2 SO 4) …

Identifying the stability and phytotoxicity of liquid digestate (LD) is necessary for safe
agricultural utilization. Storage temperature, method, and time are critical factors that affect …

Land spreading of liquid animal manure (slurry) is a major source of atmospheric emissions.
Ammonia (NH 3) emission is of concern, as it is one of the main contributors to ambient air …

Animal slurry contains plant nutrients such as nitrogen (N) that are essential for crop
production. Inorganic slurry N is easily volatilised as ammonia after field application …

Ammonia (NH3) emissions vary considerably among farms as influenced by climate and
management. Because emission measurement is difficult and expensive, process‐based …

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 …
