Growing Cucumber in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Marsabit County is a challenging environment for Cucumber (soil-match score 18/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Cucumber's preferred 5.8–7 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 high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Cucumber 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 Cucumber's minimum of 500 mm — so supplemental irrigation would be essential for this crop. Cucumber's full potential is about 12,000 kg/acre (~KES 480,000/acre at KES 40/kg), but at Marsabit's 18/100 suitability a realistic target here is closer to 2,700 kg/acre (~KES 108,000/acre) unless the constraints above are addressed.
