Growing Cassava in Narok

Soil suitability analysis based on Narok's nutrient profile

Narok County is a solid choice for Cassava, with a soil-match score of 62/100. Local soils average pH 6.13 — slightly acidic to near-neutral and inside the 4.5–7 band Cassava prefers, so no lime is usually required. Nitrogen (1.63 g/kg), phosphorus (25.7 mg/kg) and potassium (234 mg/kg) all meet Cassava's requirements, so a maintenance fertilizer programme is enough. Cassava prefers sandy soils, while Narok is largely clay loam, so drainage and organic-matter management matter more here. At 1700 m, the county sits above Cassava's preferred altitude ceiling of 1400 m, where frost risk and cold nights reduce the crop's productivity. Cassava's full potential is about 6,000 kg/acre (~KES 90,000/acre at KES 15/kg), but at Narok's 62/100 suitability a realistic target here is closer to 4,650 kg/acre (~KES 69,750/acre) unless the constraints above are addressed.
