Growing Tangerine in Marsabit

Soil suitability analysis based on Marsabit's nutrient profile

Marsabit County is a challenging environment for Tangerine (soil-match score 14/100) and will need significant amendment before planting. At an average pH of 8.22 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 0.52 g/kg, P 37.3 mg/kg, K 420 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. Tangerine prefers loam soils, while Marsabit is largely sandy, so drainage and organic-matter management matter more here. Marsabit receives approximately 300 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 #55 soil match of the 106 crops we assess for Marsabit County. Tangerine's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Marsabit's 14/100 suitability a realistic target here is closer to 1,750 kg/acre (~KES 105,000/acre) unless the constraints above are addressed.

Better matched to Marsabit's soil: Sisal, Chia, and Aloe Vera — each scores higher on the same soil.
