Simple fertilizer technique promises to feed Africa's hungry

A simple and cheap technique of applying fertilizer in small doses at the right time can double wheat crop yields in sub-Saharan Africa and feed millions of people, agronomists said in a report.

A four-year experiment with the technique in Mali, Burkina Faso and Niger has boosted sorghum and millet production by 44 to 120 percent, and family incomes by 50 to 130 percent, said an International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) report published Thursday.
