Growing Cashew Nuts in Embu
Soil suitability analysis based on Embu's nutrient profile
Generally not ideal — Embu is poorly suited to Cashew Nuts. Embu's soil (pH 5.1, strongly acidic) gives Cashew Nuts a suitability score of 10/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Embu County is a challenging environment for Cashew Nuts (soil-match score 10/100) and will need significant amendment before planting. Local soils average pH 5.1 — moderately acidic and inside the 5–7.5 band Cashew Nuts prefers, so no lime is usually required. Nitrogen (1.04 g/kg), phosphorus (12.6 mg/kg) and potassium (194 mg/kg) all meet Cashew Nuts's requirements, so a maintenance fertilizer programme is enough. Cashew Nuts prefers sandy soils, while Embu is largely clay loam, so drainage and organic-matter management matter more here. At 1400 m, the county sits above Cashew Nuts's preferred altitude ceiling of 500 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Cashew Nuts is the #105 soil match of the 106 crops we assess for Embu County. Cashew Nuts's full potential is about 900 kg/acre (~KES 247,500/acre at KES 275/kg), but at Embu's 10/100 suitability a realistic target here is closer to 113 kg/acre (~KES 31,075/acre) unless the constraints above are addressed.
Better matched to Embu's soil: Pineapple, Avocado, and Macadamia — each scores higher on the same soil.

Top dressing guide
Embu's nitrogen (1.04 g/kg) already meets Cashew Nuts's 0.5 g/kg requirement, so this is a maintenance rate.
