Growing Carrot in Vihiga

Soil suitability analysis based on Vihiga's nutrient profile

Quick answer

Yes, with the right inputs — Vihiga is moderately suited to Carrot. Vihiga's soil (pH 5.62, slightly acidic) gives Carrot a suitability score of 64/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.

Vihiga County is a solid choice for Carrot, with a soil-match score of 64/100. Local soils average pH 5.62 — slightly acidic to near-neutral and inside the 5.5–7 band Carrot prefers, so no lime is usually required. The main gap is potassium — measured at N 1.02 g/kg, P 14.8 mg/kg, K 164 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 Vihiga 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 Vihiga's 64/100 suitability a realistic target here is closer to 8,000 kg/acre (~KES 304,000/acre) unless the constraints above are addressed.
