Growing Chickpeas in Isiolo

Soil suitability analysis based on Isiolo's nutrient profile

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. At current prices (about KES 200/kg) and a typical 500 kg/acre yield, a well-managed Chickpeas crop here can gross roughly KES 100,000 per acre.
