Growing Chickpeas in Isiolo
Soil suitability analysis based on Isiolo's nutrient profile
Generally not ideal — Isiolo is poorly suited to Chickpeas. Isiolo's soil (pH 7.83, alkaline) gives Chickpeas a suitability score of 26/100. Match fertilizer to Isiolo's nitrogen and phosphorus levels for the best result.
Isiolo County is a challenging environment for Chickpeas (soil-match score 26/100) and will need significant amendment before planting. Local soils average pH 7.83 — alkaline and inside the 5.5–8 band Chickpeas prefers, so no lime is usually required. 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/low/low demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Chickpeas, which favours sandy loam. At 900 m, the county sits below Chickpeas's preferred altitude range (1500–2600 m), which limits yield potential due to heat stress. On ShambaIQ's soil-match model, Chickpeas is the #44 soil match of the 106 crops we assess for Isiolo County. Chickpeas's full potential is about 600 kg/acre (~KES 120,000/acre at KES 200/kg), but at Isiolo's 26/100 suitability a realistic target here is closer to 195 kg/acre (~KES 39,000/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.
