For resource poor smallholders, fertilizer in small doses pays off [Registered]

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. “Microdosing involves applying a small, affordable amount of fertilizer with the seed at planting time or as top dressing three to four weeks after emergence,” explained…
