Models are great tools for predicting and estimating how environmental systems change. We use them all the time for understanding global circulation models, but they also are used extensively in developing carbon budgets for greenhouse gas emissions accounting. Like all models, soil modelling approaches are constantly improving. We are developing and verifying the impact of several management approaches on carbon and nitrogen models, including manure amendments, nitrogen dynamics and plant inputs. As an example, Canada’s National Inventory Report
The ISMC is a group that has a common interest in soil modelling. The link above takes you to a compilation of models that are currently available, each with its own particular focus.
