Growing Tangerine in Kilifi

Soil suitability analysis based on Kilifi's nutrient profile

Quick answer

Yes, with the right inputs — Kilifi is moderately suited to Tangerine. Kilifi's soil (pH 6.24, slightly acidic) gives Tangerine a suitability score of 70/100. Match fertilizer to Kilifi's nitrogen and phosphorus levels for the best result.

Kilifi County is a solid choice for Tangerine, with a soil-match score of 70/100. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 6–7.5 band Tangerine prefers, so no lime is usually required. The main gap is nitrogen, phosphorus, and potassium — measured at N 0.8 g/kg, P 11 mg/kg, K 109 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly sandy loam soils suit Tangerine, which favours loam. On ShambaIQ's soil-match model, Tangerine is the #51 soil match of the 106 crops we assess for Kilifi County. Tangerine's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Kilifi's 70/100 suitability a realistic target here is closer to 8,750 kg/acre (~KES 525,000/acre) unless the constraints above are addressed.
