Growing Grapes in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Turkana County is a challenging environment for Grapes (soil-match score 21/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Grapes's preferred 6–7.5 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 medium/high/high demand — so the fertilizer plan below prioritises closing that deficit. Grapes 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 Grapes's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Grapes is the #22 soil match of the 106 crops we assess for Turkana County. Grapes's full potential is about 8,000 kg/acre (~KES 1,200,000/acre at KES 150/kg), but at Turkana's 21/100 suitability a realistic target here is closer to 2,100 kg/acre (~KES 315,000/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.
