Growing Wheat in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Wheat can be grown in Nyandarua County, but the soil scores 59/100 and needs targeted management to reach full potential. At an average pH of 5.38 the soil is moderately acidic, below Wheat's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus — measured at N 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's high/high/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay soils suit Wheat, which favours clay. At current prices (about KES 50/kg) and a typical 1,000 kg/acre yield, a well-managed Wheat crop here can gross roughly KES 50,000 per acre.
