Growing Sisal in Meru

Soil suitability analysis based on Meru's nutrient profile

Quick answer

Generally not ideal — Meru is poorly suited to Sisal. Meru's soil (pH 4.88, strongly acidic) gives Sisal a suitability score of 30/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Meru County is a challenging environment for Sisal (soil-match score 30/100) and will need significant amendment before planting. At an average pH of 4.88 the soil is strongly acidic, below Sisal's preferred 5.5–8.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.22 g/kg), phosphorus (20.3 mg/kg) and potassium (218 mg/kg) all meet Sisal's requirements, so a maintenance fertilizer programme is enough. Sisal prefers sandy soils, while Meru is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Sisal is the #102 soil match of the 106 crops we assess for Meru County. Sisal's full potential is about 1,000 kg/acre (~KES 90,000/acre at KES 90/kg), but at Meru's 30/100 suitability a realistic target here is closer to 375 kg/acre (~KES 33,750/acre) unless the constraints above are addressed.

Better matched to Meru's soil: Tea, Avocado, and Macadamia — each scores higher on the same soil.
