Activity 4: Validation and transfer of alternative agro-ecological techniques to improve resource management

The innovative agro-ecological techniques discovered within the framework of the BIOVA project are all tested either in the laboratory or in experimental trials and in the field. Among other things, they allow the understanding of crop-livestock integration and the design of better management of the conditions of fertility and productivity of agricultural soils. In particular, BIOVA will study upland rice production associated with forage crops, the conservation of biomass for animal feeding and the conservation of nutrients in organic fertilizers.

Activity 4 tests a certain number of innovative agro-ecological techniques that will allow better integration of agriculture and livestock, a more efficient conservation of nutrients along the chain of interactions between these two activities, and finally better management of the conditions of fertility and productivity of agricultural soils. A network of on-farm trials will be carried out on thirty plots in each country.

For this, it focuses on three types of specific practices:

  • conservation agriculture systems (CA) aimed at stabilizing food production such as upland rice and increasing and diversifying forage production through the incorporation of forage cover crops;
  • improvement of biomass conservation for animal feeding. The conservation of forage (carryover forage) in the form of hay or silage is one of the means of adapting livestock systems to the seasonal variability of herbage yields. It helps the maintenance of forage availability throughout the year and the minimum to cover the needs of the herd during the period of maximum deficit in forage resources (lack of grass and crop residues);
  • improvement of conservation of nutrients in organic fertilizers (manure, compost). In the context where fertilizer prices have become inaccessible for the majority of farmers, animal organic matter (hen manure, slurry, manure, compost) is the only fertilizer locally produced for the maintenance of soil fertility.

These different practices will be evaluated at the technical (yield, animal productivity, soil fertility, etc.), environmental (carbon storage, GHG reduction), but also at the economic level (margin, income). The commercial component may also work as a driver for the management of biomass and soil fertility.
