As the global community marks World Soil Day, African smallholder farmers are contending with low yields due to low-fertility soils prevalent in most parts of sub-Saharan Africa, affecting food security for 300 million people.

Green manures are an affordable and environmentally friendly alternative to fertilizer for many farmers in southern Africa.

A testament to increased climate variability and risk for farming systems already operating on the razor’s edge, the 2014-15 cropping season will be recognized as a sad write-off by most farmers in Central Mozambique. The rains started six weeks late and most of the rainfall fell in only two months (normally it’s distributed over four), followed by a long drought and some few showers at the end.

Sub-Saharan African farmers typically apply less than 20 kilograms of fertilizer per hectare of cropland — far less than their peers in any other region of the world. In 2014, partners in the Improved Maize for African Soils (IMAS) project developed 41 Africa-adapted maize varieties that respond better to low amounts of nitrogen fertilizer and are up for release in nine African countries through 24 seed companies.

When traveling from Chimoio to Tete along one of the main roads in central Mozambique, one inevitably passes through Malomue, a small rural village in Báruè District. Since 2008, conservation agriculture (CA) technologies and improved drought-tolerant maize varieties have been promoted to farmers through various donor-funded projects, including a USAID-funded Feed the Future initiative.
