Growing Soybeans in Kitui

Soil suitability analysis based on Kitui's nutrient profile

Soybeans can be grown in Kitui County, but the soil scores 53/100 and needs targeted management to reach full potential. At an average pH of 7.03 the soil sits above Soybeans's preferred 5–7 range, which can limit uptake of phosphorus and micronutrients. Nitrogen (0.74 g/kg), phosphorus (30.5 mg/kg) and potassium (339 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.
