Growing Carrot in Kirinyaga

Soil suitability analysis based on Kirinyaga's nutrient profile

Kirinyaga County is well suited to Carrot, scoring 75/100 on ShambaIQ's soil-match model. At an average pH of 5.31 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 1.36 g/kg, P 12.5 mg/kg, K 177 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 Kirinyaga is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 38/kg) and a typical 10,000 kg/acre yield, a well-managed Carrot crop here can gross roughly KES 380,000 per acre.
