Growing Sisal in Trans Nzoia

Soil suitability analysis based on Trans Nzoia's nutrient profile

Sisal can be grown in Trans Nzoia County, but the soil scores 45/100 and needs targeted management to reach full potential. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 5.5–8.5 band Sisal prefers, so no lime is usually required. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Sisal's requirements, so a maintenance fertilizer programme is enough. Sisal prefers sandy soils, while Trans Nzoia is largely clay loam, so drainage and organic-matter management matter more here. Sisal's full potential is about 1,000 kg/acre (~KES 90,000/acre at KES 90/kg), but at Trans Nzoia's 45/100 suitability a realistic target here is closer to 563 kg/acre (~KES 50,670/acre) unless the constraints above are addressed.
