Growing Beetroot in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

Isiolo County is a challenging environment for Beetroot (soil-match score 31/100) and will need significant amendment before planting. At an average pH of 7.83 the soil sits above Beetroot's preferred 6–7.5 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 high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Beetroot prefers loam soils, while Isiolo is largely sandy, so drainage and organic-matter management matter more here. Isiolo receives approximately 350 mm/year — well below Beetroot's minimum of 500 mm — so supplemental irrigation would be essential for this crop. Beetroot's full potential is about 10,000 kg/acre (~KES 500,000/acre at KES 50/kg), but at Isiolo's 31/100 suitability a realistic target here is closer to 3,875 kg/acre (~KES 193,750/acre) unless the constraints above are addressed.
