Growing Cauliflower in Nyandarua
Soil suitability analysis based on Nyandarua's nutrient profile
Nyandarua County is a solid choice for Cauliflower, with a soil-match score of 63/100. At an average pH of 5.38 the soil is moderately acidic, below Cauliflower's preferred 6–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is phosphorus and potassium — measured at N 1.28 g/kg, P 14 mg/kg, K 166 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Cauliflower prefers loam soils, while Nyandarua is largely clay, so drainage and organic-matter management matter more here. Cauliflower's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Nyandarua's 63/100 suitability a realistic target here is closer to 7,875 kg/acre (~KES 472,500/acre) unless the constraints above are addressed.
