Short summary
In a field experiment in Tanzania, we used substrates from local projects as soil amenders for intercropping relevant local crops, aiming to advance the practical application of known principles for smallholder agriculture in SSA, i.e. biochar and biogas application and EcoSan practices. We studied the short-term effects on crop productivity, plant nutrition and soil properties. By mitigating P scarcity and acidification, yields were increased by up to 400 % compared to the control.
