Growing Soybeans in Makueni
Soil suitability analysis based on Makueni's nutrient profile
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. At current prices (about KES 75/kg) and a typical 550 kg/acre yield, a well-managed Soybeans crop here can gross roughly KES 41,250 per acre.
