Growing Sisal in Isiolo
Soil suitability analysis based on Isiolo's nutrient profile
Isiolo County is well suited to Sisal, scoring 78/100 on ShambaIQ's soil-match model. Local soils average pH 7.83 — alkaline and inside the 5.5–8.5 band Sisal prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.46 g/kg, P 37.4 mg/kg, K 395 mg/kg against this crop's low/low/low demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Sisal, which favours sandy. At current prices (about KES 90/kg) and a typical 900 kg/acre yield, a well-managed Sisal crop here can gross roughly KES 81,000 per acre.
