Growing Carrot in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Quick answer

Yes, with the right inputs — Kisii is moderately suited to Carrot. Kisii's soil (pH 5.21, strongly acidic) gives Carrot a suitability score of 66/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Kisii County is a solid choice for Carrot, with a soil-match score of 66/100. At an average pH of 5.21 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 1.09 g/kg, P 13.1 mg/kg, K 151 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 Kisii is largely clay loam, so drainage and organic-matter management matter more here. Carrot's full potential is about 10,000 kg/acre (~KES 380,000/acre at KES 38/kg), but at Kisii's 66/100 suitability a realistic target here is closer to 8,250 kg/acre (~KES 313,500/acre) unless the constraints above are addressed.
