Summary
The effect of keeping in situ all organic residues available on Robusta coffee farm
Amount of on-farm organic residues obtained was from 20-25 tons of fresh weight per hectare per year. Returning these residues to the soil could improve soil fertility and soil structure through positive changes of the chemical and physical contents such as porosity, aggregation, water holding capacity, P2O5 fixing… leading to increase in chemical fertilizer use efficiency. Keeping all the materials in place not only stimulated the development of coffee root system, reduced amount of dropped berries increased bean size, but also increased coffee yield by 29-80%.
