Information properties of boundary line models for N2O emissions from agricultural soils
MetadataShow full item record
Boundary line models for N2O emissions from agricultural soils provide a means of estimating emissions within defined ranges. Boundary line models partition a twodimensional region of parameter space into sub-regions by means of thresholds based on relationships between N2O emissions and explanatory variables, typically using soil data available from laboratory or field studies. Such models are intermediate in complexity between the use of IPCC emission factors and complex process-based models. Model calibration involves characterizing the extent to which observed data are correctly forecast. Different model versions may be required for different agricultural systems. Here, we interpret the information properties of boundary line models in this context.
