Growing Lentils in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

Quick answer

Generally not ideal — Isiolo is poorly suited to Lentils. Isiolo's soil (pH 7.83, alkaline) gives Lentils a suitability score of 38/100. Match fertilizer to Isiolo's nitrogen and phosphorus levels for the best result.

Isiolo County is a challenging environment for Lentils (soil-match score 38/100) and will need significant amendment before planting. At an average pH of 7.83 the soil sits above Lentils's preferred 5.5–7.5 range, which can limit uptake of phosphorus and micronutrients. The main gap is nitrogen — measured at N 0.46 g/kg, P 37.4 mg/kg, K 395 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. On ShambaIQ's soil-match model, Lentils is the #21 soil match of the 106 crops we assess for Isiolo County. Lentils's full potential is about 600 kg/acre (~KES 108,000/acre at KES 180/kg), but at Isiolo's 38/100 suitability a realistic target here is closer to 285 kg/acre (~KES 51,300/acre) unless the constraints above are addressed.

Better matched to Isiolo's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
