Crop yields in the fragile semi-arid areas of Zimbabwe have been declining over time due to a decline in soil fertility resulting from mono-cropping, lack of fertilizer, and other factors. In collaboration with the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), University of Illinois researchers evaluated the use of a precision farming technique called "microdosing," its effect on food security, and its ability to improve yield at a low cost to farmers.
