In contrast with ACR's 2010 methodology for N2O Emissions Reductions from Changes in Fertilizer Management, which
incorporates site specific data into a peer - reviewed, tested and highly parameterized computer
model to calculate N2O emission reductions resulting from changes in how fertilizer is applied and used, the MSU - EPRI methodology is based on empirical
equations and NCR data to set conservative estimates for emission reductions.
The analytic form of TOPMODEL
equations are
incorporated into the soil column framework and the resulting
model is used to predict the saturated fraction of the watershed and baseflow in a consistent fashion.
