Growing Sisal in Wajir

Soil suitability analysis based on Wajir's nutrient profile

Wajir County is a challenging environment for Sisal (soil-match score 41/100) and will need significant amendment before planting. Local soils average pH 8.4 — alkaline and inside the 5.5–8.5 band Sisal prefers, so no lime is usually required. Nitrogen (0.52 g/kg), phosphorus (39.3 mg/kg) and potassium (396 mg/kg) all meet Sisal's requirements, so a maintenance fertilizer programme is enough. 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.
