Researchers in Uganda developed an organic fertiliser from waste left by leather production. They made a gel from animal skin collagen and added nutrients like nitrogen, phosphorus and potassium. The team calls the product "smart" because it releases nutrients when the soil needs them.
Trials happened on a coffee farm in Masaka and the farmer reported strong results. He said many chemical fertilisers are not organic and that organic coffee gets better prices. The researchers aim to have a market-ready product by November and hope to sell it in nearby countries.
