Growing Grapes in Tana River

Soil suitability analysis based on Tana River's nutrient profile

Grapes can be grown in Tana River County, but the soil scores 48/100 and needs targeted management to reach full potential. Local soils average pH 6.4 — slightly acidic to near-neutral and inside the 6–7.5 band Grapes prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 1.04 g/kg, P 8.5 mg/kg, K 108 mg/kg against this crop's medium/high/high demand — so the fertilizer plan below prioritises closing those deficits. Grapes prefers loam soils, while Tana River is largely sandy, so drainage and organic-matter management matter more here. Grapes's full potential is about 8,000 kg/acre (~KES 1,200,000/acre at KES 150/kg), but at Tana River's 48/100 suitability a realistic target here is closer to 4,800 kg/acre (~KES 720,000/acre) unless the constraints above are addressed.
