If so, how many grams of nitrogen...  
  9. 2017-08-01 Faced with the challenges of smallholders in terms of agricultural inputs and the limitations of mineral fertilizer, ECHO's West Africa Impact Center has provided farmers with practical and economic knowledge. One example of this is the technique of manufacturing organic liquid fertilizer.
