Stored pig manure is a major source of greenhouse gases. In Canada, in 2008, stored pig manure released 1.3 million tons of carbon dioxide equivalent in the form of methane. Methane concentrations from pig manure storage tanks are generally too low to be burned, but biofilters can be used to manage them.

The aim of this project is to show that efforts made to better distribute phosphorus on the land are effective and that the indicators used to determine phosphorus saturation thresholds are correlated with soil phosphorus balance and dynamics.
