Growing Lentils in Lamu
Soil suitability analysis based on Lamu's nutrient profile
Generally not ideal — Lamu is poorly suited to Lentils. Lamu's soil (pH 6.31, slightly acidic) gives Lentils a suitability score of 0/100. Match fertilizer to Lamu's nitrogen and phosphorus levels for the best result.
Lamu County is a challenging environment for Lentils (soil-match score 0/100) and will need significant amendment before planting. Local soils average pH 6.31 — slightly acidic to near-neutral and inside the 5.5–7.5 band Lentils prefers, so no lime is usually required. The main gap is phosphorus — measured at N 0.74 g/kg, P 9.6 mg/kg, K 117 mg/kg against this crop's low/medium/low demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Lentils, which favours sandy loam. At 10 m, the county sits below Lentils's preferred altitude range (1200–2400 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Lentils is the #87 soil match of the 106 crops we assess for Lamu County. Lentils's full potential is about 600 kg/acre (~KES 108,000/acre at KES 180/kg), but at Lamu's 0/100 suitability a realistic target here is closer to 0 kg/acre (~KES 0/acre) unless the constraints above are addressed.
Better matched to Lamu's soil: Sesame (Simsim), Sorghum, and Cowpeas — each scores higher on the same soil.
