Growing Guava in Nyamira

Soil suitability analysis based on Nyamira's nutrient profile

Nyamira County is well suited to Guava, scoring 77/100 on ShambaIQ's soil-match model. Local soils average pH 5.58 — slightly acidic to near-neutral and inside the 5.5–7.5 band Guava prefers, so no lime is usually required. The main gap is phosphorus and potassium — measured at N 0.84 g/kg, P 11.6 mg/kg, K 148 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing those deficits. The county's predominantly clay loam soils suit Guava, which favours loam. At current prices (about KES 60/kg) and a typical 10,000 kg/acre yield, a well-managed Guava crop here can gross roughly KES 600,000 per acre.
