Growing Lentils in Kiambu
Soil suitability analysis based on Kiambu's nutrient profile
Yes, with the right inputs — Kiambu is moderately suited to Lentils. Kiambu's soil (pH 5.28, strongly acidic) gives Lentils a suitability score of 60/100. Apply agricultural lime before planting to unlock phosphorus and lift the score.
Kiambu County is a solid choice for Lentils, with a soil-match score of 60/100. At an average pH of 5.28 the soil is moderately acidic, below Lentils's preferred 5.5–7.5 range; agricultural lime will lift pH and unlock phosphorus the crop cannot otherwise access. Nitrogen (1.01 g/kg), phosphorus (13.7 mg/kg) and potassium (169 mg/kg) all meet Lentils's requirements, so a maintenance fertilizer programme is enough. Lentils prefers sandy loam soils, while Kiambu is largely clay, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Lentils is the #64 soil match of the 106 crops we assess for Kiambu County. Lentils's full potential is about 600 kg/acre (~KES 108,000/acre at KES 180/kg), but at Kiambu's 60/100 suitability a realistic target here is closer to 450 kg/acre (~KES 81,000/acre) unless the constraints above are addressed.
