Growing Carrot in Tana River
Soil suitability analysis based on Tana River's nutrient profile
Generally not ideal — Tana River is poorly suited to Carrot. Tana River's soil (pH 6.4, slightly acidic) gives Carrot a suitability score of 1/100. Match fertilizer to Tana River's nitrogen and phosphorus levels for the best result.
Tana River County is a challenging environment for Carrot (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 5.5–7 band Carrot prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's low/medium/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy soils suit Carrot, which favours sandy loam. Tana River receives approximately 400 mm/year — well below Carrot's minimum of 600 mm — so supplemental irrigation would be essential for this crop. Carrot's full potential is about 10,000 kg/acre (~KES 380,000/acre at KES 38/kg), but at Tana River's 1/100 suitability a realistic target here is closer to 125 kg/acre (~KES 4,750/acre) unless the constraints above are addressed.
