Growing Cucumber in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Cucumber (soil-match score 6/100) and will need significant amendment before planting. At an average pH of 8.38 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 0.53 g/kg, P 38.3 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 Mandera is largely sandy, so drainage and organic-matter management matter more here. Mandera receives approximately 180 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 Mandera's 6/100 suitability a realistic target here is closer to 900 kg/acre (~KES 36,000/acre) unless the constraints above are addressed.
