Growing Tangerine in Lamu

Soil suitability analysis based on Lamu's nutrient profile

Quick answer

Yes, with the right inputs — Lamu is moderately suited to Tangerine. Lamu's soil (pH 6.31, slightly acidic) gives Tangerine a suitability score of 69/100. Match fertilizer to Lamu's nitrogen and phosphorus levels for the best result.

Lamu County is a solid choice for Tangerine, with a soil-match score of 69/100. Local soils average pH 6.31 — 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 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing those deficits. Tangerine prefers loam soils, while Lamu is largely sandy, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Tangerine is the #49 soil match of the 106 crops we assess for Lamu County. Tangerine's full potential is about 10,000 kg/acre (~KES 600,000/acre at KES 60/kg), but at Lamu's 69/100 suitability a realistic target here is closer to 8,625 kg/acre (~KES 517,500/acre) unless the constraints above are addressed.
