Growing Carrot in Taita Taveta

Soil suitability analysis based on Taita Taveta's nutrient profile

Quick answer

Generally not ideal — Taita Taveta is poorly suited to Carrot. Taita Taveta's soil (pH 6.64, near-neutral) gives Carrot a suitability score of 29/100. Match fertilizer to Taita Taveta's nitrogen and phosphorus levels for the best result.

Taita Taveta County is a challenging environment for Carrot (soil-match score 29/100) and will need significant amendment before planting. Local soils average pH 6.64 — neutral and inside the 5.5–7 band Carrot prefers, so no lime is usually required. The main gap is potassium — measured at N 0.97 g/kg, P 12.9 mg/kg, K 104 mg/kg against this crop's low/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly loam soils suit Carrot, which favours sandy loam. Carrot's full potential is about 10,000 kg/acre (~KES 380,000/acre at KES 38/kg), but at Taita Taveta's 29/100 suitability a realistic target here is closer to 3,625 kg/acre (~KES 137,750/acre) unless the constraints above are addressed.
