Growing Grapes in Bomet

Soil suitability analysis based on Bomet's nutrient profile

Quick answer

Yes, with the right inputs — Bomet is moderately suited to Grapes. Bomet's soil (pH 6.02, slightly acidic) gives Grapes a suitability score of 57/100. Match fertilizer to Bomet's nitrogen and phosphorus levels for the best result.

Grapes can be grown in Bomet County, but the soil scores 57/100 and needs targeted management to reach full potential. Local soils average pH 6.02 — slightly acidic to near-neutral and inside the 6–7.5 band Grapes prefers, so no lime is usually required. Nitrogen (1.38 g/kg), phosphorus (23.6 mg/kg) and potassium (237 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 #74 soil match of the 106 crops we assess for Bomet County. Grapes's full potential is about 8,000 kg/acre (~KES 1,200,000/acre at KES 150/kg), but at Bomet's 57/100 suitability a realistic target here is closer to 5,700 kg/acre (~KES 855,000/acre) unless the constraints above are addressed.

Better matched to Bomet's soil: Wambugu Apples, Kale (Sukuma Wiki), and Garden Peas — each scores higher on the same soil.
