CLIMATE SMART CASHEW - Agronomic tests on the Biochar benefits in Mozambique

December 2023
December 2025
Project cost
21 000 USD
Role in the project




Agriculture Organic Agriculture Bioenergy Climate Degradation-Restoration



Main goals

Assess the benefits of Biochar application on the growth and mortality of cashew seedlings during the plantation of a new cashew orchard, as well as on the productivity of annual food crop (cassava) cultivated in association with new cashew trees. The biochar is made from the carbonization of cashew nut shells

Specific objectives

SO1. Definition and implementation of an experimental protocol in a farming environment, on sandy soils with 4 treatments for cassava (control, biochar, biochar + NPK, NPK) and 4 treatments for cashew seedlings (control, biochar, biocher + EM ®™, EM ®™). EM are a combination of beneficial micro-organisms: bacteria, yeasts, fungi.
SO2. Evaluate the impact of biochar on water retention and the effect of combining biochar with mineral fertilisers and with the addition of microorgnisms in the soil on the mortality and growth of cashew trees and on cassava production.


R1. Implementation of the protocol on 4 plots of 0.5 ha
R2. Comparison of cashew tree mortality and growth according to the different treatments
R3. Comparison of cassava production according to the different treatments


A1. Definition and drafting of the protocol with the Norwegian University of Life Sciences
A2. Implementation and monitoring of the experiment
A3. Analysing the results and creating training materials on this basis
