After a period of 6 to 10 month of maturation, the discomposed human excreta can be applied as a very potent fertilizer. The gardeners of Fada N'Gourma reported that they get a much higher output using faecal sludge as fertilizer and compared to chemical fertilizer it doesn't burn the crop. In Fada N'Gourma, human excreta are also (but less often) used for crop like maize, milet, sorgo etc.. Observe how the fertilizer is given directly at the foot of the plant, to avoid erosion.
