Growing Lentils in Meru

Soil suitability analysis based on Meru's nutrient profile

Quick answer

Possible but challenging — Meru is only marginally suited to Lentils. Meru's soil (pH 4.88, strongly acidic) gives Lentils a suitability score of 42/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.

Meru County is a challenging environment for Lentils (soil-match score 42/100) and will need significant amendment before planting. At an average pH of 4.88 the soil is strongly acidic, below Lentils's preferred 5.5–7.5 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 Lentils's requirements, so a maintenance fertilizer programme is enough. Lentils prefers sandy loam soils, while Meru is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Lentils is the #85 soil match of the 106 crops we assess for Meru County. Lentils's full potential is about 600 kg/acre (~KES 108,000/acre at KES 180/kg), but at Meru's 42/100 suitability a realistic target here is closer to 315 kg/acre (~KES 56,700/acre) unless the constraints above are addressed.

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