Growing Cabbage in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Quick answer

Generally not ideal — Turkana is poorly suited to Cabbage. Turkana's soil (pH 7.95, alkaline) gives Cabbage a suitability score of 2/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.

Turkana County is a challenging environment for Cabbage (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Cabbage's preferred 5–7.5 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/high/high demand — so the fertilizer plan below prioritises closing that deficit. Cabbage prefers clay loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. Turkana receives approximately 300 mm/year — well below Cabbage's minimum of 700 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Cabbage is the #80 soil match of the 106 crops we assess for Turkana County. Cabbage's full potential is about 15,000 kg/acre (~KES 270,000/acre at KES 18/kg), but at Turkana's 2/100 suitability a realistic target here is closer to 375 kg/acre (~KES 6,750/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.

Turkana's nitrogen (0.41 g/kg) is 34% of the 1.2 g/kg Cabbage needs, so the standard 1 bag/acre is raised to 1.5. Split it across two applications to limit leaching.
