Zaï (or plant-pit system) is a soil and water conservation technique used to restore, maintain or improve soil fertility. This paper discusses the advantages of the Zaï technique, its impact on agricultural productivity, and its adoption by farmers of Burkina Faso. Apparently, the Zä technique have been mastered by farmers of the central region of the country. Studies on sorghum in 2002 and 2003 revealed that the Zaï technique increases crop yields, reduces risks of food insecurity, and results in soil improvement and recuperation of degraded lands. Recommendations are given to maximize the benefits of this technique, including the chemical analysis of organic manures used by farmers and the identification of appropriate dosages, and the testing of highly productive cultivars.
