Abstract
131 words
Food insecurity in sub-Saharan Africa (SSA) results mainly
from common and prolonged droughts, fertility depleted soils,
poor economies and insignificant researcher-extension-farmer
contacts to demonstrate technologies. The soils are
predominantly deficient in N and P nutrients, soil organic matter
and are generally acidic. In these soils nutrient additions have
raised maize (staple) yields in western Kenya from 0.5 to 3-5 t/
ha/season, when 75 kg N, 26 kg P and 2 t/ha agricultural lime
are applied. Farmers always indicate the unaffordable costs of
these materials. To mitigate these problems, cooperation among
international institutions has been launched in the region to
diversify fertilizer and lime applications, to reach 50,000 farmers
by 2012. Use of low cost materials such as phosphate rocks,
lime and manures is emphasized. This paper highlights some of
these efforts.
