A new framework for simulating C decomposition and emissions from land applied biosolids and manures using the denitrification and decomposition model.

There is a need for modeling tools capable of estimating CO emissions from land application of biosolids and manure. The Denitrification and Decomposition model (DNDC) was improved for this capacity by adding a separate manure C pool to disaggregate manure decomposition from the soil organic matter pools. The effect of soil temperature on soil organic matter decomposition was also improved.
