The African Soil Information Services project prepares the first digital map of African soil. The map will provide updated information on soil status and properties in 42 sub-Saharan countries. To do this, they will measure by satellite the amount of nutrients, humidity and organic matter of the land. In addition to satellite measurements, samples will be taken in 60 randomly selected locations over the next four years, measuring the chemical and physical properties of the earth. Farmers in the area will now get a unique source of information they haven't had so far.
