Soil fertility is important to ensuring a good harvest, as described in two of our Farmer stories this week. Often, chemical fertilizers are expensive, so it is best to optimize their use. Organic fertilizers can be very effective. Integrated soil fertility management is based on maximizing the use of organic fertilizers and minimizing the loss of soil nutrients, to achieve a cost-effective strategy for maintaining and improving soil fertility.

Reviving soil with mucuna (EN/FR +)
In the coastal savannah of West Africa, farmers explain how a mucuna cover crop helped to revive their highly degraded soil, and suppress the noxious weeds Striga and Imperata. They show how to grow mucuna to benefit your maize and cassava, and why discussing land tenure in your community really matters.
Human urine as fertilizer (EN)
Land in the Tororo district of Uganda has been intensively used and soil fertility is low and declining. This video shows a possible solution—using human urine as a fertilizer.
Growing cassava in poor soils (EN/FR +)
Farmers in Cote d’Ivoire show how they improve their cassava production and restore soil fertility. The farmers follow five practices. They: use improved varieties that are resistant to the cassava mosaic virus; apply organic matter; apply small doses of mineral fertilizer; plant the cassava in rows, leaving sufficient space between the rows; and, grow rows of legumes between their cassava rows.
