Growing Pineapple in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Pineapple can be grown in Nyandarua County, but the soil scores 56/100 and needs targeted management to reach full potential. Local soils average pH 5.38 — moderately acidic and inside the 4.5–6.5 band Pineapple 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 medium/low/high demand — so the fertilizer plan below prioritises closing that deficit. Pineapple prefers sandy loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. At 2300 m, the county sits above Pineapple's preferred altitude ceiling of 1800 m, where frost risk and cold nights reduce the crop's productivity. At current prices (about KES 35/kg) and a typical 30,000 kg/acre yield, a well-managed Pineapple crop here can gross roughly KES 1,050,000 per acre.
