Tithonia green manure for soil fertility improvement in western Kenya small holder farms

Export citation

The use of commercial fertilizers for the growing of staple food crops of maize and beans in Western Kenya is generally restricted to only a few farmers who are endowed with resources such as cattle and land and with high off-farm income. The majority of the small holder farmers on the other hand lack the financial resources to buy the recommended fertilizers to replace soil nutrients removed from the soil with harvested crops. As a result soil fertility has reduced and the yields of crops are typically low.
