Growing Lentils in Kitui
Soil suitability analysis based on Kitui's nutrient profile
Possible but challenging — Kitui is only marginally suited to Lentils. Kitui's soil (pH 7.03, near-neutral) gives Lentils a suitability score of 49/100. Match fertilizer to Kitui's nitrogen and phosphorus levels for the best result.
Lentils can be grown in Kitui County, but the soil scores 49/100 and needs targeted management to reach full potential. Local soils average pH 7.03 — neutral and inside the 5.5–7.5 band Lentils prefers, so no lime is usually required. Nitrogen (0.74 g/kg), phosphorus (30.5 mg/kg) and potassium (339 mg/kg) all meet Lentils's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Lentils, which favours sandy loam. On ShambaIQ's soil-match model, Lentils is the #58 soil match of the 106 crops we assess for Kitui County. Lentils's full potential is about 600 kg/acre (~KES 108,000/acre at KES 180/kg), but at Kitui's 49/100 suitability a realistic target here is closer to 368 kg/acre (~KES 66,240/acre) unless the constraints above are addressed.
Better matched to Kitui's soil: Mango, Sisal, and Moringa — each scores higher on the same soil.
