This dataset contains paired wet and dry chemistry measurements for georeferenced soil samples that were collected through the Africa Soil Information Service (AfSIS) project, which lasted from 2009 through 2018. In this release, we include data collected during Phase I (2009-2013.) Georeferenced samples were collected from many Sub-Saharan African countries, and their soil properties were analyzed using both wet and dry chemistry. The two types of data can be paired to form a training dataset for machine learning, such that certain soil properties can be well-predicted through less expensive dry chemistry techniques.
