Nairobi County is well suited to Tree Tomato (Tamarillo), scoring 87/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 5.8–7 band Tree Tomato (Tamarillo) 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 Tree Tomato (Tamarillo), which favours loam. On ShambaIQ's soil-match model, Tree Tomato (Tamarillo) is the #47 soil match of the 106 crops we assess for Nairobi County.
