Growing Soybeans in Wajir
Soil suitability analysis based on Wajir's nutrient profile
Generally not ideal — Wajir is poorly suited to Soybeans. Wajir's soil (pH 8.4, alkaline) gives Soybeans a suitability score of 6/100. Match fertilizer to Wajir's nitrogen and phosphorus levels for the best result.
Wajir County is a challenging environment for Soybeans (soil-match score 6/100) and will need significant amendment before planting. At an average pH of 8.4 the soil sits above Soybeans's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.52 g/kg), phosphorus (39.3 mg/kg) and potassium (396 mg/kg) all meet Soybeans's requirements, so a maintenance fertilizer programme is enough. Soybeans prefers loam soils, while Wajir is largely sandy, so drainage and organic-matter management matter more here. Wajir receives approximately 200 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 #37 soil match of the 106 crops we assess for Wajir County. Soybeans's full potential is about 700 kg/acre (~KES 52,500/acre at KES 75/kg), but at Wajir's 6/100 suitability a realistic target here is closer to 53 kg/acre (~KES 3,975/acre) unless the constraints above are addressed.
Better matched to Wajir's soil: Sisal, Aloe Vera, and Green Grams — each scores higher on the same soil.

Top dressing guide
Wajir's nitrogen reads 0.52 g/kg, but the rate stays at zero: Soybeans is not top-dressed, for the crop-specific reason above.
Recommended seed varieties
No variety in our list is specifically rated for Wajir's 250 m altitude and 200 mm rainfall, so all 2 are shown. Confirm with your agrovet before buying.
