Growing Garden Peas in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Generally not ideal — Turkana is poorly suited to Garden Peas. Turkana's soil (pH 7.95, alkaline) gives Garden Peas a suitability score of 1/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a challenging environment for Garden Peas (soil-match score 1/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Garden Peas's preferred 5.5–7 range, which can limit uptake of phosphorus and micronutrients. 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/medium/medium demand — so the fertilizer plan below prioritises closing that deficit. The county's predominantly sandy soils suit Garden Peas, which favours sandy loam. Turkana receives approximately 300 mm/year — well below Garden Peas's minimum of 800 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Garden Peas is the #96 soil match of the 106 crops we assess for Turkana County. Garden Peas's full potential is about 2,500 kg/acre (~KES 362,500/acre at KES 145/kg), but at Turkana's 1/100 suitability a realistic target here is closer to 31 kg/acre (~KES 4,495/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.
