Uranium (U) is a toxic heavy metal. The background values of natural soils differ between 0.79–11 mg kg
−1
U. U is accumulated in the A horizons and its plant availability is influenced by both natural soil properties and anthropogenic activities. Recently, the use of phosphorus fertilizers in agriculture will be reported as a longer-term risk for the soil-plant-system. An alien source of environmental pollution results from military operations. Soil fertility, pH value and nutrient supply can effect the U content of crops growing on U contaminated soils.
