Growing Carrot in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for Carrot (soil-match score 15/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Carrot's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.67 g/kg), phosphorus (42.1 mg/kg) and potassium (387 mg/kg) all meet Carrot's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Carrot, which favours sandy loam. Samburu 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.
