Growing Sisal in Kisii

Soil suitability analysis based on Kisii's nutrient profile

Kisii County is a challenging environment for Sisal (soil-match score 32/100) and will need significant amendment before planting. At an average pH of 5.21 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 (1.09 g/kg), phosphorus (13.1 mg/kg) and potassium (151 mg/kg) all meet Sisal's requirements, so a maintenance fertilizer programme is enough. Sisal prefers sandy soils, while Kisii is largely clay loam, so drainage and organic-matter management matter more here. 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.
