Growing Cucumber in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Generally not ideal — Turkana is poorly suited to Cucumber. Turkana's soil (pH 7.95, alkaline) gives Cucumber a suitability score of 18/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a challenging environment for Cucumber (soil-match score 18/100) and will need significant amendment before planting. At an average pH of 7.95 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 0.41 g/kg, P 38.5 mg/kg, K 417 mg/kg against this crop's high/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Cucumber prefers loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. Turkana receives approximately 300 mm/year — well below Cucumber's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Cucumber is the #30 soil match of the 106 crops we assess for Turkana County. Cucumber's full potential is about 12,000 kg/acre (~KES 480,000/acre at KES 40/kg), but at Turkana'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.
Better matched to Turkana's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Turkana's nitrogen (0.41 g/kg) is 34% of the 1.2 g/kg Cucumber needs, so the standard 0.4 bags/acre is raised to 0.5. Split it across two applications to limit leaching.
