Growing Sisal in Nairobi

Soil suitability analysis based on Nairobi's nutrient profile

Nairobi County is well suited to Sisal, scoring 80/100 on ShambaIQ's soil-match model. Local soils average pH 6.85 — neutral and inside the 5.5–8.5 band Sisal prefers, so no lime is usually required. Nitrogen (1.1 g/kg), phosphorus (22.1 mg/kg) and potassium (236 mg/kg) all meet Sisal's requirements, so a maintenance fertilizer programme is enough. Sisal prefers sandy soils, while Nairobi is largely clay loam, so drainage and organic-matter management matter more here. 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.
