Microdosing in Zimbabwe

microdosingImpact of Fertilizer Microdosing Research and Development in Semi-Arid Zimbabwe

Land degradation is particularly acute in sub-saharan African regions where long-term overuse of soil and low, unpredictable rainfall are prime reasons for poor food production. The farmers are so poor that they take everything they can out of the soil and are not willing to invest in fertilizer because the growing season is very risky. The failure to replenish the soil fuels an unrelenting, vicious cycle. Unless nutrients are replaced, soils are depleted and yields and crop quality decline, leading to widespread hunger and under nutrition.

Pigeonpea in Tanzania

1375090885_1Assessment of the impact of Improved Pigeonpea Development in Northern Tanzania

Pigeonpea (Cajanus cajan) is one of the most important food crops grown in eastern and southern Africa. Farmers love this crop for many reasons – tolerance to drought, important source of protein for the family, vital source of scarce cash, and provider of fodder for livestock. Pigeonpea fixes soil nitrogen, allowing the poor farmers to improve soil fertility without expensive chemical fertilizers. Farmers have evolved elaborate intercropping systems allowing them to plant pigeonpeas with maize, sorghum and other cereals making it highly suited to semi-arid, low soil fertility areas.

Sorghum in Mali

Farmers-in-the-field-with-Improved-Deko-12KNICSV-188-1024x612An Economic Assessment of Sorghum Improvement in Mali

Sorghum is an extraordinarily robust and reliable crop that grows over a wide range of temperatures and elevations. It performs well in different soil types – from very porous sandy soils that don’t retain water to heavy clay-types that are prone to water logging. It has tremendous resilience in the face of drought and not only survives but still produces grain using only residual moisture. It is resistant to grain mold, giving people and animals protection against the health dangers of contamination by mycotoxins.
