Growing Chickpeas in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Generally not ideal — Turkana is poorly suited to Chickpeas. Turkana's soil (pH 7.95, alkaline) gives Chickpeas a suitability score of 5/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a challenging environment for Chickpeas (soil-match score 5/100) and will need significant amendment before planting. Local soils average pH 7.95 — alkaline and inside the 5.5–8 band Chickpeas prefers, so no lime is usually required. The main gap is nitrogen — measured at N 0.41 g/kg, P 38.5 mg/kg, K 417 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 400 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 #64 soil match of the 106 crops we assess for Turkana County. Chickpeas's full potential is about 600 kg/acre (~KES 120,000/acre at KES 200/kg), but at Turkana's 5/100 suitability a realistic target here is closer to 38 kg/acre (~KES 7,600/acre) unless the constraints above are addressed.
Better matched to Turkana's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
