Growing Capsicum in Nairobi
Soil suitability analysis based on Nairobi's nutrient profile
Nairobi County is well suited to Capsicum, scoring 84/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 5.5–7 band Capsicum prefers, so no lime is usually required. The main gap is nitrogen — measured at N 1.1 g/kg, P 22.1 mg/kg, K 236 mg/kg against this crop's high/high/high demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Capsicum, which favours loam. At current prices (about KES 90/kg) and a typical 4,500 kg/acre yield, a well-managed Capsicum crop here can gross roughly KES 405,000 per acre.
