Growing Chickpeas in Garissa
Soil suitability analysis based on Garissa's nutrient profile
Generally not ideal — Garissa is poorly suited to Chickpeas. Garissa's soil (pH 7.96, alkaline) gives Chickpeas a suitability score of 1/100. Match fertilizer to Garissa's nitrogen and phosphorus levels for the best result.
Garissa County is a challenging environment for Chickpeas (soil-match score 1/100) and will need significant amendment before planting. Local soils average pH 7.96 — alkaline and inside the 5.5–8 band Chickpeas prefers, so no lime is usually required. Nitrogen (0.61 g/kg), phosphorus (37.7 mg/kg) and potassium (407 mg/kg) all meet Chickpeas's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy soils suit Chickpeas, which favours sandy loam. At 200 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 #72 soil match of the 106 crops we assess for Garissa County. Chickpeas's full potential is about 600 kg/acre (~KES 120,000/acre at KES 200/kg), but at Garissa's 1/100 suitability a realistic target here is closer to 8 kg/acre (~KES 1,600/acre) unless the constraints above are addressed.
Better matched to Garissa's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.
