Growing Soybeans in Makueni
Soil suitability analysis based on Makueni's nutrient profile
Yes, with the right inputs — Makueni is moderately suited to Soybeans. Makueni's soil (pH 7.5, alkaline) gives Soybeans a suitability score of 65/100. Match fertilizer to Makueni's nitrogen and phosphorus levels for the best result.
Makueni County is a solid choice for Soybeans, with a soil-match score of 65/100. At an average pH of 7.5 the soil sits above Soybeans's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.86 g/kg), phosphorus (29.6 mg/kg) and potassium (351 mg/kg) all meet Soybeans's requirements, so a maintenance fertilizer programme is enough. The county's predominantly sandy loam soils suit Soybeans, which favours loam. Soybeans's full potential is about 700 kg/acre (~KES 52,500/acre at KES 75/kg), but at Makueni's 65/100 suitability a realistic target here is closer to 569 kg/acre (~KES 42,675/acre) unless the constraints above are addressed.
