Growing Oats in Nyandarua

Soil suitability analysis based on Nyandarua's nutrient profile

Nyandarua County is well suited to Oats, scoring 77/100 on ShambaIQ's soil-match model. At an average pH of 5.38 the soil is moderately acidic, below Oats's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.28 g/kg), phosphorus (14 mg/kg) and potassium (166 mg/kg) all meet Oats's requirements, so a maintenance fertilizer programme is enough. Oats prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 40/kg) and a typical 1,600 kg/acre yield, a well-managed Oats crop here can gross roughly KES 64,000 per acre.
