Growing Sisal in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Laikipia County is a solid choice for Sisal, with a soil-match score of 61/100. At an average pH of 4.99 the soil is strongly acidic, below Sisal's preferred 5.5–8.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 mg/kg) all meet Sisal's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam 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 Laikipia's 61/100 suitability a realistic target here is closer to 763 kg/acre (~KES 68,670/acre) unless the constraints above are addressed.
