[Q] Soil layer options

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 […]

A New Global High-Resolution Soil Profile Database for DSSAT

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

Converting WISE 1.1 Soil Profile Database for Crop Models

Through the collaboration with HarvestChoice, a team of scientists at the Universities of Georgia and Florida converted 3,404 soil profiles from the World Soil Information (ISRIC) WISE Global Soil Profile Database v1.1 to the DSSAT-compatible format. Beyond the specific locations, this large collection of soil profiles can be used by crop modeling researchers as a […]

HC27: Generic Soil Profiles

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 […]
