Growing Sisal in Nyamira
Soil suitability analysis based on Nyamira's nutrient profile
Generally not ideal — Nyamira is poorly suited to Sisal. Nyamira's soil (pH 5.58, slightly acidic) gives Sisal a suitability score of 35/100. Match fertilizer to Nyamira's nitrogen and phosphorus levels for the best result.
Nyamira County is a challenging environment for Sisal (soil-match score 35/100) and will need significant amendment before planting. Local soils average pH 5.58 — slightly acidic to near-neutral and inside the 5.5–8.5 band Sisal prefers, so no lime is usually required. Nitrogen (0.84 g/kg), phosphorus (11.6 mg/kg) and potassium (148 mg/kg) all meet Sisal's requirements, so a maintenance fertilizer programme is enough. Sisal prefers sandy soils, while Nyamira is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Sisal is the #94 soil match of the 106 crops we assess for Nyamira County. Sisal's full potential is about 1,000 kg/acre (~KES 90,000/acre at KES 90/kg), but at Nyamira'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 Nyamira's soil: Sweet Potato, Soybeans, and Pineapple — each scores higher on the same soil.

Top dressing guide
Nyamira's nitrogen reads 0.84 g/kg, but the rate stays at zero: Sisal is not top-dressed, for the crop-specific reason above.
