Growing Soybeans in Marsabit
Soil suitability analysis based on Marsabit's nutrient profile
Generally not ideal — Marsabit is poorly suited to Soybeans. Marsabit's soil (pH 8.22, alkaline) gives Soybeans a suitability score of 14/100. Match fertilizer to Marsabit's nitrogen and phosphorus levels for the best result.
Marsabit County is a challenging environment for Soybeans (soil-match score 14/100) and will need significant amendment before planting. At an average pH of 8.22 the soil sits above Soybeans's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.52 g/kg), phosphorus (37.3 mg/kg) and potassium (420 mg/kg) all meet Soybeans's requirements, so a maintenance fertilizer programme is enough. Soybeans prefers loam soils, while Marsabit is largely sandy, so drainage and organic-matter management matter more here. Marsabit 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 #46 soil match of the 106 crops we assess for Marsabit County. Soybeans's full potential is about 700 kg/acre (~KES 52,500/acre at KES 75/kg), but at Marsabit's 14/100 suitability a realistic target here is closer to 122 kg/acre (~KES 9,150/acre) unless the constraints above are addressed.
Better matched to Marsabit's soil: Sisal, Chia, and Aloe Vera — each scores higher on the same soil.

Top dressing guide
Marsabit's nitrogen reads 0.52 g/kg, but the rate stays at zero: Soybeans is not top-dressed, for the crop-specific reason above.
