Growing Chickpeas in Mandera

Soil suitability analysis based on Mandera's nutrient profile

Mandera County is a challenging environment for Chickpeas (soil-match score 2/100) and will need significant amendment before planting. At an average pH of 8.38 the soil sits above Chickpeas's preferred 5.5–8 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.53 g/kg), phosphorus (38.3 mg/kg) and potassium (420 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 250 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.
