Growing Rice (Upland) in Embu

Soil suitability analysis based on Embu's nutrient profile

Quick answer

Yes, with the right inputs — Embu is moderately suited to Rice (Upland). Embu's soil (pH 5.1, strongly acidic) gives Rice (Upland) a suitability score of 67/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Embu County is a solid choice for Rice (Upland), with a soil-match score of 67/100. Local soils average pH 5.1 — moderately acidic and inside the 5–7 band Rice (Upland) prefers, so no lime is usually required. The main gap is nitrogen — measured at N 1.04 g/kg, P 12.6 mg/kg, K 194 mg/kg against this crop's high/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly clay loam soils suit Rice (Upland), which favours clay. On ShambaIQ's soil-match model, Rice (Upland) is the #31 soil match of the 106 crops we assess for Embu County. Rice (Upland)'s full potential is about 1,800 kg/acre (~KES 189,000/acre at KES 105/kg), but at Embu's 67/100 suitability a realistic target here is closer to 1,508 kg/acre (~KES 158,340/acre) unless the constraints above are addressed.
