Growing Lentils in Vihiga
Soil suitability analysis based on Vihiga's nutrient profile
Possible but challenging — Vihiga is only marginally suited to Lentils. Vihiga's soil (pH 5.62, slightly acidic) gives Lentils a suitability score of 41/100. Match fertilizer to Vihiga's nitrogen and phosphorus levels for the best result.
Vihiga County is a challenging environment for Lentils (soil-match score 41/100) and will need significant amendment before planting. Local soils average pH 5.62 — slightly acidic to near-neutral and inside the 5.5–7.5 band Lentils prefers, so no lime is usually required. Nitrogen (1.02 g/kg), phosphorus (14.8 mg/kg) and potassium (164 mg/kg) all meet Lentils's requirements, so a maintenance fertilizer programme is enough. Lentils prefers sandy loam soils, while Vihiga is largely clay loam, so drainage and organic-matter management matter more here. On ShambaIQ's soil-match model, Lentils is the #81 soil match of the 106 crops we assess for Vihiga County. Lentils's full potential is about 600 kg/acre (~KES 108,000/acre at KES 180/kg), but at Vihiga's 41/100 suitability a realistic target here is closer to 308 kg/acre (~KES 55,440/acre) unless the constraints above are addressed.
Better matched to Vihiga's soil: Sweet Potato, Soybeans, and Coffee (Arabica) — each scores higher on the same soil.
