Growing Carrot in Kiambu

Soil suitability analysis based on Kiambu's nutrient profile

Kiambu County is well suited to Carrot, scoring 78/100 on ShambaIQ's soil-match model. At an average pH of 5.28 the soil is moderately acidic, below Carrot's preferred 5.5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. The main gap is potassium — measured at N 1.01 g/kg, P 13.7 mg/kg, K 169 mg/kg against this crop's low/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Carrot prefers sandy loam soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 38/kg) and a typical 5,500 kg/acre yield, a well-managed Carrot crop here can gross roughly KES 209,000 per acre.
