Growing Okra in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Marsabit County is a challenging environment for Okra (soil-match score 21/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Okra's preferred 6–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.52 g/kg, P 37.3 mg/kg, K 420 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Okra prefers loam soils, while Marsabit is largely sandy, so drainage and organic-matter management matter more here. Marsabit receives approximately 300 mm/year — well below Okra's minimum of 500 mm — so supplemental irrigation would be essential for this crop. Okra's full potential is about 5,000 kg/acre (~KES 300,000/acre at KES 60/kg), but at Marsabit's 21/100 suitability a realistic target here is closer to 1,313 kg/acre (~KES 78,780/acre) unless the constraints above are addressed.
