Growing Sisal in Vihiga
Soil suitability analysis based on Vihiga's nutrient profile
Generally not ideal — Vihiga is poorly suited to Sisal. Vihiga's soil (pH 5.62, slightly acidic) gives Sisal a suitability score of 35/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.
Vihiga County is a challenging environment for Sisal (soil-match score 35/100) and will need significant amendment before planting. Local soils average pH 5.62 — slightly acidic to near-neutral and inside the 5.5–8.5 band Sisal prefers, so no lime is usually required. Nitrogen (1.02 g/kg), phosphorus (14.8 mg/kg) and potassium (164 mg/kg) all meet Sisal's requirements, so a maintenance fertilizer programme is enough. Sisal prefers sandy soils, while Vihiga is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Sisal is the #90 soil match of the 106 crops we assess for Vihiga County. Sisal's full potential is about 1,000 kg/acre (~KES 90,000/acre at KES 90/kg), but at Vihiga's 35/100 suitability a realistic target here is closer to 438 kg/acre (~KES 39,420/acre) unless the constraints above are addressed.
Better matched to Vihiga's soil: Sweet Potato, Soybeans, and Coffee (Arabica) — each scores higher on the same soil.

Top dressing guide
Vihiga's nitrogen reads 1.02 g/kg, but the rate stays at zero: Sisal is not top-dressed, for the crop-specific reason above.
