Kitui County is well suited to Amaranth, scoring 80/100 on ShambaIQ's soil-match model. Local soils average pH 7.03 — neutral and inside the 5.5–7.5 band Amaranth 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 high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy loam soils suit Amaranth, which favours loam. On ShambaIQ's soil-match model, Amaranth is the #29 soil match of the 106 crops we assess for Kitui County. At current prices (about KES 40/kg) and a typical 5,000 kg/acre yield, a well-managed Amaranth crop here can gross roughly KES 200,000 per acre.
