Growing Carrot in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Turkana County is a challenging environment for Carrot (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Carrot's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's low/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Carrot, which favours sandy loam. Turkana receives approximately 300 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 Turkana's 2/100 suitability a realistic target here is closer to 250 kg/acre (~KES 9,500/acre) unless the constraints above are addressed.
