Growing Tangerine in Samburu

Soil suitability analysis based on Samburu's nutrient profile

Samburu County is a challenging environment for Tangerine (soil-match score 18/100) and will need significant amendment before planting. At an average pH of 8.28 the soil sits above Tangerine's preferred 6–7.5 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 high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Tangerine prefers loam soils, while Samburu is largely sandy, so drainage and organic-matter management matter more here. Samburu receives approximately 350 mm/year — well below Tangerine's minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Tangerine is the #53 soil match of the 106 crops we assess for Samburu County. Tangerine's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Samburu's 18/100 suitability a realistic target here is closer to 2,250 kg/acre (~KES 135,000/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.
