Kitui County is well suited to Rosemary, scoring 89/100 on ShambaIQ's soil-match model. Local soils average pH 7.03 — neutral and inside the 6–8 band Rosemary prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.74 g/kg, P 30.5 mg/kg, K 339 mg/kg against this crop's medium/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Rosemary, which favours sandy loam. On ShambaIQ's soil-match model, Rosemary is the #9 soil match of the 106 crops we assess for Kitui County. At current prices (about KES 150/kg) and a typical 2,500 kg/acre yield, a well-managed Rosemary crop here can gross roughly KES 375,000 per acre.
