Growing Okra in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

Isiolo County is a challenging environment for Okra (soil-match score 33/100) and will need significant amendment before planting. At an average pH of 7.83 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 0.46 g/kg, P 37.4 mg/kg, K 395 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Okra 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 Okra's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Okra is the #25 soil match of the 106 crops we assess for Isiolo County. Okra's full potential is about 5,000 kg/acre (~KES 300,000/acre at KES 60/kg), but at Isiolo's 33/100 suitability a realistic target here is closer to 2,063 kg/acre (~KES 123,780/acre) unless the constraints above are addressed.

Better matched to Isiolo's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
