Growing Grapes in Nakuru
Soil suitability analysis based on Nakuru's nutrient profile
Nakuru County is well suited to Grapes, scoring 89/100 on ShambaIQ's soil-match model. Local soils average pH 6.28 — slightly acidic to near-neutral and inside the 6–7.5 band Grapes prefers, so no lime is usually required. Nitrogen (1.59 g/kg), phosphorus (25.2 mg/kg) and potassium (239 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. 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.
