Growing Banana in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Banana can be grown in Nyandarua County, but the soil scores 51/100 and needs targeted management to reach full potential. Local soils average pH 5.38 — moderately acidic and inside the 5–7 band Banana prefers, so no lime is usually required. The main gap is potassium — measured at N 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Banana prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. At 2300 m, the county sits above Banana's preferred altitude ceiling of 1800 m, where frost risk and cold nights reduce the crop's productivity. At current prices (about KES 12/kg) and a typical 7,500 kg/acre yield, a well-managed Banana crop here can gross roughly KES 90,000 per acre.
