Growing Rice (Upland) in Laikipia

Soil suitability analysis based on Laikipia's nutrient profile

Quick answer

Generally not ideal — Laikipia is poorly suited to Rice (Upland). Laikipia's soil (pH 4.99, strongly acidic) gives Rice (Upland) a suitability score of 26/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Laikipia County is a challenging environment for Rice (Upland) (soil-match score 26/100) and will need significant amendment before planting. At an average pH of 4.99 the soil is strongly acidic, below Rice (Upland)'s preferred 5–7 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.42 g/kg), phosphorus (16.6 mg/kg) and potassium (215 mg/kg) all meet Rice (Upland)'s requirements, so a maintenance fertilizer programme is enough. Rice (Upland) prefers clay soils, while Laikipia is largely sandy loam, so drainage and organic-matter management matter more here. At 1700 m, the county sits above Rice (Upland)'s preferred altitude ceiling of 1300 m, where frost risk and cold nights reduce the crop's productivity. On ShambaIQ's soil-match model, Rice (Upland) is the #97 soil match of the 106 crops we assess for Laikipia County. Rice (Upland)'s full potential is about 1,800 kg/acre (~KES 189,000/acre at KES 105/kg), but at Laikipia's 26/100 suitability a realistic target here is closer to 585 kg/acre (~KES 61,425/acre) unless the constraints above are addressed.

Better matched to Laikipia's soil: Sweet Potato, Finger Millet, and Groundnuts — each scores higher on the same soil.
