Growing Okra in Garissa
Soil suitability analysis based on Garissa's nutrient profile
Garissa County is a challenging environment for Okra (soil-match score 17/100) and will need significant amendment before planting. At an average pH of 7.96 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 0.61 g/kg, P 37.7 mg/kg, K 407 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. Okra prefers loam soils, while Garissa is largely sandy, so drainage and organic-matter management matter more here. Garissa receives approximately 250 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 Garissa's 17/100 suitability a realistic target here is closer to 1,063 kg/acre (~KES 63,780/acre) unless the constraints above are addressed.
