Growing Carrot in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

Isiolo County is a challenging environment for Carrot (soil-match score 17/100) and will need significant amendment before planting. At an average pH of 7.83 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 0.46 g/kg, P 37.4 mg/kg, K 395 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. Isiolo receives approximately 350 mm/year — well below Carrot's minimum of 600 mm — so supplemental irrigation would be essential for this crop. At current prices (about KES 38/kg) and a typical 5,500 kg/acre yield, a well-managed Carrot crop here can gross roughly KES 209,000 per acre.
