MUKONO – Makerere University’s College of Agricultural and Environmental Sciences has taken a bold step towards sustainable agriculture by spearheading the development of a groundbreaking organic bio-fertilizer.
The innovation is designed to boost soil health, enhance food safety, and improve vegetable yields for smallholder farmers across Uganda.
The innovative product, currently undergoing field trials in Nabitimpa village, Katogo Parish, Nama Sub- County, Mukono District, is a blend of organic matter and beneficial microorganisms formulated to naturally revitalize degraded soils and reduce dependence on chemical fertilizers.
Developed by the School of Nutrition and Biosystems engineering, the bio-fertilizer project is part of a wider research initiative promoting eco-friendly farming techniques across Uganda.
The pilot phase is focused on evaluating the product’s effectiveness in real farming conditions, particularly among vegetable growers who are increasingly grappling with soil exhaustion and food contamination concerns linked to synthetic inputs.
Speaking at the project’s inception meeting in Mukono, Eng. Paddy Ainebyona, the project administrator, said the initiative seeks to transform local vegetable farming by offering a sustainable alternative that restores soil productivity and safeguards consumer health.
“This project combines scientific research with farmer training to address the challenges of declining soil fertility and food insecurity. It’s not just a fertilizer; it’s a catalyst for environmental sustainability and rural economic empowerment,” Eng. Ainebyona said.
He emphasized that the project aligns with Uganda’s national agricultural development priorities and global sustainability goals.
Local authorities have welcomed the initiative with enthusiasm. Paul Nyanja, Agricultural Officer for Nama Sub- County, applauded Makerere University for choosing their community for the pilot and praised farmers for embracing the innovation.
“This partnership gives our farmers access to cutting-edge agricultural solutions. We are confident it will lead to better harvests, safer food, and improved livelihoods,” Nyanja said.
Jimmy Katumba, a chemist and member of the research team, explained that the field trials will assess various application rates of the fertilizer and their effect on crop yields and food safety.
“We’re working to determine the optimal dosage that enhances both soil health and crop quality. Our goal is to ensure the product meets strict food safety standards while remaining practical for everyday use by farmers,” Katumba noted.
The team is also addressing potential risks and is committed to developing a standardized product that can be safely and widely adopted using locally available organic materials.
Praise Ahimbisa, a Bioprocessing Engineering student and one of the project scientists, outlined the technical innovation behind the fertilizer.
“The production process leverages microbiology, biotechnology, and process engineering. We’re creating a living product that enriches the soil with nutrients and microbial life essential for sustainable farming,” she said.
“Laboratory tests confirm its microbial viability, nutrient content, and stability meet regulatory standards,” she added.
Dr. Agnes Nabubuya, a senior lecturer in food safety and analysis at Makerere and the project’s Principal Investigator, called on farmers to play an active role in the project’s implementation.
“We are not just conducting research for publication. This project belongs to the farmers. Their participation, feedback, and adoption will determine its success,” Dr. Nabubuya stressed.
She explained that the project offers a holistic model that merges innovation with community engagement. Key outcomes include improved soil fertility, higher vegetable production, and reduced risks of food contamination.
Mukono District was strategically selected for the pilot due to its dense population of vegetable farmers and their openness to agricultural innovation.
The community in Nabitimpa village has already demonstrated willingness to participate, making it an ideal testing ground for the bio-fertilizer’s impact.
As the project advances, researchers hope its success in Mukono will pave the way for national rollout—ushering in a new era of healthier soils, safer food, and more resilient farming communities across Uganda.
