Growing Cassava in Embu

Soil suitability analysis based on Embu's nutrient profile

Quick answer

Yes — Embu is well suited to Cassava. Embu's soil (pH 5.1, strongly acidic) gives Cassava a suitability score of 87/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Embu County is well suited to Cassava, scoring 87/100 on ShambaIQ's soil-match model. Local soils average pH 5.1 — moderately acidic and inside the 4.5–7 band Cassava prefers, so no lime is usually required. Nitrogen (1.04 g/kg), phosphorus (12.6 mg/kg) and potassium (194 mg/kg) all meet Cassava's requirements, so a maintenance fertilizer programme is enough. Cassava prefers sandy soils, while Embu is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Cassava is the #4 soil match of the 106 crops we assess for Embu County. At current prices (about KES 15/kg) and a typical 6,000 kg/acre yield, a well-managed Cassava crop here can gross roughly KES 90,000 per acre.
