Growing Soybeans in Turkana
Soil suitability analysis based on Turkana's nutrient profile
Generally not ideal — Turkana is poorly suited to Soybeans. Turkana's soil (pH 7.95, alkaline) gives Soybeans a suitability score of 13/100. Match fertilizer to Turkana's nitrogen and phosphorus levels for the best result.
Turkana County is a challenging environment for Soybeans (soil-match score 13/100) and will need significant amendment before planting. At an average pH of 7.95 the soil sits above Soybeans's preferred 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. Soybeans prefers loam soils, while Turkana is largely sandy, so drainage and organic-matter management matter more here. Turkana receives approximately 300 mm/year — well below Soybeans's minimum of 600 mm — so supplemental irrigation would be essential for this crop. On ShambaIQ's soil-match model, Soybeans is the #47 soil match of the 106 crops we assess for Turkana County. Soybeans's full potential is about 700 kg/acre (~KES 52,500/acre at KES 75/kg), but at Turkana's 13/100 suitability a realistic target here is closer to 114 kg/acre (~KES 8,550/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.

Top dressing guide
Turkana's nitrogen reads 0.41 g/kg, but the rate stays at zero: Soybeans is not top-dressed, for the crop-specific reason above.
