Service Description:This map is based on the Fertility Capability Classification described by Pedro Sanchez and colleagues. 21 different soil constraints were mapped. Several of these were of particular interest to the GCP. Aluminum toxicity, phosphorus fixation and salinity are the focus of research efforts by the program. The base map upon which these constraints maps are developed is the one to 5 million digital soil map of the world. These soil constraints maps can be downloaded here. Sanchez, P.A., C.A.
