Mapping the global extent of soil constraints to crop growth plays an important role in developing strategies for agricultural production, environmental protection, and sustainable development at regional and global scales. The most widely used dataset is the Soil Fertility Capability Classification System (FCC) developed by Center for International Earth Science Information Network (CIESIN) and the Tropical Agriculture Program of the Earth Institute at Columbia University. HarvestChoice facilitated developing an updated version of FCC using the Harmonized World Soil Database v1.1. This new dataset will play a key role in HarvestChoice's forthcoming flagship study on the biophysical/economic impact assessment of agricultural production constraints in Sub-Saharan Africa.

By modeling the decomposition of soil organic matter dynamics, crop systems models can simulate the effects of soil nutrient depletion under low-input extractive field management practices, as well as soil carbon sequestration under regenerative management practices.
