Plant your own fertiliser factory
The leaves of the Faidherbia albida tree are rich in nitrogen, phosphorus and other nutrients. Plants that grow beneath the trees benefit from their annual leaf fall, which fertilises the soil and counteracts soil acidity. In Zambia, the Conservation Farming Unit is encouraging farmers to plant 100 of the trees per hectare, at 10 metre intervals, as a long term means of boosting soil fertility. Over 160,000 farmers have already begun to do so.
