Growing Avocado in Trans Nzoia

Soil suitability analysis based on Trans Nzoia's nutrient profile

Quick answer

Yes — Trans Nzoia is well suited to Avocado. Trans Nzoia's soil (pH 5.93, slightly acidic) gives Avocado a suitability score of 90/100. Match fertilizer to Trans Nzoia's nitrogen and phosphorus levels for the best result.

Trans Nzoia County is well suited to Avocado, scoring 90/100 on ShambaIQ's soil-match model. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 4.5–6.5 band Avocado prefers, so no lime is usually required. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Avocado's requirements, so a maintenance fertilizer programme is enough. Avocado prefers sandy loam soils, while Trans Nzoia is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Avocado is the #15 soil match of the 106 crops we assess for Trans Nzoia County. At current prices (about KES 18/kg) and a typical 6,000 kg/acre yield, a well-managed Avocado crop here can gross roughly KES 108,000 per acre.
