In Mzimba District in Northern Malawi many farmers have seen lower crop yields and rising costs for chemical fertiliser. Local people say smallholders cannot afford commercial fertiliser and farm incomes are under pressure.
Researchers at Mzuzu University, working with the Science Granting Councils Initiative and Malawi’s National Commission for Science and Technology, developed an organic fertiliser from black soldier fly frass, rice husk biochar and used coffee grounds. The mix is tested in a laboratory, left to dry and then packaged for use.
The project includes training. Two people from one village taught eight others and opened a trial farm. Farmers who used the fertiliser report better crop growth and lower costs.
