Growing Lentils in Trans Nzoia

Soil suitability analysis based on Trans Nzoia's nutrient profile

Quick answer

Yes, with the right inputs — Trans Nzoia is moderately suited to Lentils. Trans Nzoia's soil (pH 5.93, slightly acidic) gives Lentils a suitability score of 66/100. Match fertilizer to Trans Nzoia's nitrogen and phosphorus levels for the best result.

Trans Nzoia County is a solid choice for Lentils, with a soil-match score of 66/100. Local soils average pH 5.93 — slightly acidic to near-neutral and inside the 5.5–7.5 band Lentils prefers, so no lime is usually required. Nitrogen (1.68 g/kg), phosphorus (27.3 mg/kg) and potassium (213 mg/kg) all meet Lentils's requirements, so a maintenance fertilizer programme is enough. Lentils prefers sandy loam soils, while Trans Nzoia is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Lentils is the #73 soil match of the 106 crops we assess for Trans Nzoia County. Lentils's full potential is about 600 kg/acre (~KES 108,000/acre at KES 180/kg), but at Trans Nzoia's 66/100 suitability a realistic target here is closer to 495 kg/acre (~KES 89,100/acre) unless the constraints above are addressed.
