There are 3 methods of dealing with soil layers in DSSAT, controlled by MESOL in simulation controls: MESOL = 1: old DSSAT method of forcing soil layer thicknesses to be 5, 10, 15, 15, 15, 30, 30, 30, 60, 60, 60 cm thick. Soil properties are blended when user input layers are forced to standard […]
The HarvestChoice Project at IFPRI, in collaboration with IRI at Columbia University and Michigan State University, published a working paper on the development of a new, global high-resolution soil profile database for DSSAT. The dataset is freely available at IFPRI’s Dataverse at http://dx.doi.org/10.7910/DVN/1PEEY0.
Biophysical models are commonly used in ecosystem impact assessment studies at different temporal and spatial scales, and their results implicate decisions on the overall system at multiple levels—from micro-scale natural resource management to country- or regional-scale policy decisions. In agricultural systems, soil data is often key for understanding the current status of the ecosystem and […]
Complex crop systems models require detailed soil property data that are not always available at regional-level and often blocks scaling up modeling studies. As an option, HarvestChoice presents a pragmatic approach that attempts to characterize any type of soil with a set of 27 generic soil profiles. This dataset, called HC27, may not replace the […]
