Growing Dragon Fruit in Turkana

Soil suitability analysis based on Turkana's nutrient profile

Turkana County is a challenging environment for Dragon Fruit (soil-match score 18/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Dragon Fruit's preferred 5.5–7 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 medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Dragon Fruit, which favours sandy loam. Turkana receives approximately 300 mm/year — well below Dragon Fruit's minimum of 500 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Dragon Fruit is the #34 soil match of the 106 crops we assess for Turkana County. Dragon Fruit's full potential is about 5,000 kg/acre (~KES 2,500,000/acre at KES 500/kg), but at Turkana's 18/100 suitability a realistic target here is closer to 1,125 kg/acre (~KES 562,500/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.
