Growing Napier Grass in Murang'a

Soil suitability analysis based on Murang'a's nutrient profile

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. At current prices (about KES 5/kg) and a typical 15,000 kg/acre yield, a well-managed Napier Grass crop here can gross roughly KES 75,000 per acre.
