The Kenya Agricultural and Livestock Research Organization (KALRO) has been at the forefront of researching biochar's potential in the local context. Their extensive 2025 studies provided compelling evidence: biochar application significantly boosts soil water retention by up to 30%, a critical factor in arid and semi-arid regions of Kenya. Furthermore, it effectively reduces fertilizer leaching, meaning valuable nutrients stay in the root zone longer, enhancing plant uptake and reducing waste.
Building on these foundational insights, 2026 field trials conducted by KALRO yielded even more exciting results. These trials specifically focused on maize production in clay soils, a common agricultural land type in Kenya. The findings were remarkable: farms applying an optimal mix of biochar and compost observed a staggering 25% higher maize yield compared to plots treated with traditional compost alone. This robust evidence underscores biochar's role not just as a soil amendment, but as a yield-enhancing catalyst.
When Compost Remains Superior: Addressing Sandy Soils
While biochar offers incredible benefits, it's important to recognize that compost still holds a critical, often superior, role in certain scenarios. Specifically, for sandy soils with very low organic matter, compost remains the immediate go-to solution.
Compost instantly introduces a wealth of organic material, beneficial microorganisms, and readily available nutrients that sandy soils desperately lack. This immediate organic matter boost improves soil structure, enhances nutrient holding capacity, and kick-starts microbial activity, which is vital for overall soil health. Biochar, while excellent for long-term water and nutrient retention, does not provide the same immediate organic matter or nutrient richness as a well-made compost. Therefore, in severely degraded sandy soils, prioritize a generous application of compost to bring the soil to life, with biochar then acting as a powerful long-term conditioner. For a reliable way to produce your own nutrient-rich compost, consider the Worm Factory 360 Composting Bin – available on Amazon.
