PHYTOSTABILIZATION OF ZN AND CD IN MINE SOIL USING CORN IN COMBINATION WITH BIOCHARS AND MANURE-BASED COMPOST

The effect of biochar additions (BA) with or without manure-based compost (MBC) was evaluated on shoots biomass, roots biomass, uptake, and the bioconcentration factor (BCF) of Zn and Cd in corn (Zea mays L.) grown in mine soil. Biochar additions of beef cattle manure (BCM), poultry litter (PL), and lodgepole pine were applied at 0, 2.5, and 5.0% (w/w) in combination with different rates (0, 2.5, and 5.0%, w/w) of MBC, respectively. Shoots and roots uptake of Cd and Zn were significantly affected by BA, MBC, and the interaction of BA and MBC. Corn plants that received 2.5% PL and 2.5% BCM had the greatest Cd and Zn shoot uptake, respectively. Corn plants with 5% BCM had the greatest Cd and Zn root uptake. When averaged across BAs, the greatest BCF for Cd in the shoot (92.3) was from application of BCM and the least BCF was from application of PL (72.8). The incorporation of biochar enhanced phytostabilization of Cd and Zn. Concentrations of water-soluble Cd and Zn were lowest in soils amended with manure-based biochars, which improved the biomass productivity of corn.
