Crop Residue Management [Madagascar]

Crop residue management consists of leaving crop residues on farmland after harvest. This reduces evaporation during the dry season. The decomposition of the residues contributes to improved soil fertility, while the underground biomass (roots) enhances soil structure. In the case of legumes, root nodules provide nitrogen for subsequent crops.

Liquid Compost [Madagascar]

Liquid compost is produced by chopping and mixing animal dung and fresh plant matter, including plants with insect-repellent properties, in an aqueous medium. This liquid compost can be used as a substitute for mineral fertilizers and for pest control in crops. It can be used on all types of crops, …

Intercropping of Maize and Cowpeas [Madagascar]

Intercropping maize with legumes improves soil fertility and provides a rapid source of income for smallholders. Red cowpea, known locally as “lojy zazamena”, is the most widely used legume, but there are also other varieties of cowpea (Vigna unguiculata) that adapt well to the region's environmental conditions.

Grass strips enriched with Cajanus cajan
technologies

Grass strips enriched with Cajanus cajan [Madagascar]

Grass strips enriched with Cajanus cajan (pigeon pea) are established at regular distances along a slope, ideally following the contour lines. They primarily function as anti-erosion barriers, but also produce food and fodder resources while contributing to soil fertility.

Soil Regeneration through Cajanus cajan  (pigeon pea) mini-forests
technologies

Soil Regeneration through Cajanus cajan (pigeon pea) mini-forests [Madagascar]

Cajanus cajan, commonly known as pigeon pea, is a perennial shrub legume that thrives in nutrient-deficient soils and exhibits resilience to water scarcity. Cultivating pigeon pea contributes to the rejuvenation of impoverished soils through fixing atmospheric nitrogen and its leaf litter, while concurrently yielding food, fodder, and fuelwood.

Basket Composting
technologies

Basket Composting [Madagascar]

Basket composting enhances the yield of tubers such as cassava by producing concentrated organic matter that adds fertility to the soil. This technique proves to be highly advantageous for small-scale farmers with limited land, allowing them to maximize production within a confined space.
