In Mbooni sub-county, Kenya, Martin Muoki, a horticulture graduate from Jomo Kenyatta University of Agriculture and Technology, is transforming farming through innovative soil testing and integrated agriculture. After quitting formal employment, Muoki initially faced repeated failures in his farming ventures. Instead of giving up, he turned to scientific methods, partnering with KALRO to conduct soil analysis. This revealed key deficiencies in the region’s soils, particularly issues like bacterial wilt, root rot, and nutrient imbalances caused by acidic soils. Using this knowledge, Muoki developed targeted solutions that now help over 3,000 farmers across three wards improve productivity and crop health.
His model farm is a showcase of sustainable, circular farming systems. Muoki uses biogas from cow dung to power irrigation and equipment, significantly cutting energy costs. He also cultivates azolla, a nitrogen-rich aquatic plant, which feeds his fish and supplements cattle and poultry diets. This integrated approach reduces waste, increases output, and creates employment for six full-time workers and around 200 women who earn income from selling produce in local markets. Muoki maintains communication with his farmer network via phone and WhatsApp, offering guidance and tailored solutions based on ongoing soil assessments.
The larger context of Muoki’s work highlights a critical issue in the region—widespread soil degradation due to poor nutrient management, erosion, and acidification. According to Dr Anne Bakilana of the World Bank, over 65% of farmland in the region suffers from reduced fertility, threatening food security. Experts like Marisa Soares from Yara International stress the need for regular pH correction and tailored fertiliser use to restore soil health. Muoki’s work demonstrates how locally driven, science-based solutions can address these challenges, making farming more viable and sustainable in the face of climate change and declining soil quality.
