Growing Dragon Fruit in Samburu
Soil suitability analysis based on Samburu's nutrient profile
Generally not ideal — Samburu is poorly suited to Dragon Fruit. Samburu's soil (pH 8.28, alkaline) gives Dragon Fruit a suitability score of 26/100. Match fertilizer to Samburu's nitrogen and phosphorus levels for the best result.
Samburu County is a challenging environment for Dragon Fruit (soil-match score 26/100) and will need significant amendment before planting. At an average pH of 8.28 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 0.67 g/kg, P 42.1 mg/kg, K 387 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. Samburu receives approximately 350 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 #33 soil match of the 106 crops we assess for Samburu County. Dragon Fruit's full potential is about 5,000 kg/acre (~KES 2,500,000/acre at KES 500/kg), but at Samburu's 26/100 suitability a realistic target here is closer to 1,625 kg/acre (~KES 812,500/acre) unless the constraints above are addressed.
Better matched to Samburu's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
