Murang'a County is a solid choice for Napier Grass, with a soil-match score of 69/100. Local soils average pH 5.03 — moderately acidic and inside the 5–8 band Napier Grass prefers, so no lime is usually required. Nitrogen (1.2 g/kg), phosphorus (12.2 mg/kg) and potassium (168 mg/kg) all meet Napier Grass's requirements, so a maintenance fertilizer programme is enough. Napier Grass prefers loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. Napier Grass's full potential is about 30,000 kg/acre (~KES 150,000/acre at KES 5/kg), but at Murang'a's 69/100 suitability a realistic target here is closer to 25,875 kg/acre (~KES 129,375/acre) unless the constraints above are addressed.
