Growing Sweet Potato in Murang'a

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

Murang'a County is well suited to Sweet Potato, scoring 83/100 on ShambaIQ's soil-match model. Local soils average pH 5.03 — moderately acidic and inside the 4.5–7 band Sweet Potato prefers, so no lime is usually required. The main gap is potassium — measured at N 1.2 g/kg, P 12.2 mg/kg, K 168 mg/kg against this crop's low/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Sweet Potato prefers sandy loam soils, while Murang'a is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 18/kg) and a typical 3,500 kg/acre yield, a well-managed Sweet Potato crop here can gross roughly KES 63,000 per acre.
