Growing Wambugu Apples in Kiambu

Soil suitability analysis based on Kiambu's nutrient profile

Kiambu County is well suited to Wambugu Apples, scoring 83/100 on ShambaIQ's soil-match model. Local soils average pH 5.28 — moderately acidic and inside the 5–7 band Wambugu Apples prefers, so no lime is usually required. The main gap is potassium — measured at N 1.01 g/kg, P 13.7 mg/kg, K 169 mg/kg against this crop's medium/medium/high demand — so the fertilizer plan below prioritises closing that deficit. Wambugu Apples prefers loam soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. At current prices (about KES 75/kg) and a typical 2,000 kg/acre yield, a well-managed Wambugu Apples crop here can gross roughly KES 150,000 per acre.
