Growing Sisal in Embu

Soil suitability analysis based on Embu's nutrient profile

Embu County is a challenging environment for Sisal (soil-match score 36/100) and will need significant amendment before planting. At an average pH of 5.1 the soil is moderately acidic, below Sisal's preferred 5.5–8.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.04 g/kg), phosphorus (12.6 mg/kg) and potassium (194 mg/kg) all meet Sisal's requirements, so a maintenance fertilizer programme is enough. Sisal prefers sandy soils, while Embu 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 Embu's 36/100 suitability a realistic target here is closer to 450 kg/acre (~KES 40,500/acre) unless the constraints above are addressed.
