Bioavailability of Vanadium in Alfalfa in V-Cd Contaminated Soil

Abstract:

A greenhouse experiment was performed to investigate the vanadium bioavailability of alfalfa grown in vanadium-cadmium contaminated soil. The results show bioavailable and total vanadium concentration in rhizosphere soil is higher than it in non-rhizosphere soil. With increasing vanadium addition, its speciation in soil is transformed to AC, RE, and OX fraction, especially to RE fraction. Alfalfa has high vanadium accumulation (up to 1221.86 mg/kg), and 70% of root samples belonged to strong absorption to vanadium. Both bioavailable and total vanadium in rhizosphere and non-rhizosphere soil have direct correlation with its content in alfalfa root. The increasing cadmium addition may inhibit vanadium absorption in alfalfa roots.
