Growing Grapes in Nairobi
Soil suitability analysis based on Nairobi's nutrient profile
Yes — Nairobi is well suited to Grapes. Nairobi's soil (pH 6.85, near-neutral) gives Grapes a suitability score of 92/100. Match fertilizer to Nairobi's nitrogen and phosphorus levels for the best result.
Nairobi County is well suited to Grapes, scoring 92/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 6–7.5 band Grapes prefers, so no lime is usually required. Nitrogen (1.1 g/kg), phosphorus (22.1 mg/kg) and potassium (236 mg/kg) all meet Grapes's requirements, so a maintenance fertilizer programme is enough. The county's predominantly clay loam soils suit Grapes, which favours loam. On ShambaIQ's soil-match model, Grapes is the #14 soil match of the 106 crops we assess for Nairobi County. At current prices (about KES 150/kg) and a typical 8,000 kg/acre yield, a well-managed Grapes crop here can gross roughly KES 1,200,000 per acre.
