Growing Sisal in Kisii
Soil suitability analysis based on Kisii's nutrient profile
Generally not ideal — Kisii is poorly suited to Sisal. Kisii's soil (pH 5.21, strongly acidic) gives Sisal a suitability score of 32/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
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. On ShambaIQ's soil-match model, Sisal is the #99 soil match of the 106 crops we assess for Kisii County. Sisal's full potential is about 1,000 kg/acre (~KES 90,000/acre at KES 90/kg), but at Kisii's 32/100 suitability a realistic target here is closer to 400 kg/acre (~KES 36,000/acre) unless the constraints above are addressed.
Better matched to Kisii's soil: Tea, Macadamia, and Pineapple — each scores higher on the same soil.
