Growing Sisal in Mombasa

Soil suitability analysis based on Mombasa's nutrient profile

Mombasa County is a solid choice for Sisal, with a soil-match score of 66/100. Local soils average pH 6.24 — slightly acidic to near-neutral and inside the 5.5–8.5 band Sisal prefers, so no lime is usually required. Nitrogen (0.95 g/kg), phosphorus (8.4 mg/kg) and potassium (136 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. Sisal's full potential is about 1,000 kg/acre (~KES 90,000/acre at KES 90/kg), but at Mombasa's 66/100 suitability a realistic target here is closer to 825 kg/acre (~KES 74,250/acre) unless the constraints above are addressed.
