This Agrodok is a revised edition, which incorporates two previously published Agrodoks (Agrodok 2: Soil Fertility, and Agrodok 28: Green Manures). These were combined because they canít be dealt with separately: green manures offer the small-scale farmer extra opportunities to improve soil fertility. In addition to animal manure and chemical fertiliser, crop husbandry measures, such as the use of green manure, are important in combatting soil fertility problems. 
 

Fourth edition: 2004
