Growing Mango in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Quick answer

Possible but challenging — Tana River is only marginally suited to Mango. Tana River's soil (pH 6.4, slightly acidic) gives Mango a suitability score of 54/100. Match fertilizer to Tana River's nitrogen and phosphorus levels for the best result.

Mango can be grown in Tana River County, but the soil scores 54/100 and needs targeted management to reach full potential. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 5.5–8.5 band Mango prefers, so no lime is usually required. The main gap is potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's low/low/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Mango, which favours sandy. Mango's full potential is about 8,000 kg/acre (~KES 80,000/acre at KES 10/kg), but at Tana River's 54/100 suitability a realistic target here is closer to 5,400 kg/acre (~KES 54,000/acre) unless the constraints above are addressed.
