Growing Potato in Kiambu

Soil suitability analysis based on Kiambu's nutrient profile

Kiambu County is well suited to Potato, scoring 82/100 on ShambaIQ's soil-match model. Local soils average pH 5.28 — moderately acidic and inside the 4.8–6.5 band Potato prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 1.01 g/kg, P 13.7 mg/kg, K 169 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Potato prefers sandy loam soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 32/kg) and a typical 4,000 kg/acre yield, a well-managed Potato crop here can gross roughly KES 128,000 per acre.
