Murang'a County is a solid choice for Cassava, with a soil-match score of 74/100. Local soils average pH 5.03 — moderately acidic and inside the 4.5–7 band Cassava prefers, so no lime is usually required. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (168 mg/kg) all meet Cassava's requirements, so a maintenance fertilizer programme is enough. Cassava prefers sandy soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Cassava is the #18 soil match of the 106 crops we assess for Murang'a County. At current prices (about KES 15/kg) and a typical 6,000 kg/acre yield, a well-managed Cassava crop here can gross roughly KES 90,000 per acre.
