Cadmium uptake by ryegrass and ryegrass-clover mixtures under different liming rates

Ebrahim Benyas, Jennifer Owens, Salome' Seyedalikhani & Brett Robinson
Cadmium accumulates in soils that receive repeated applications of Cd-rich superphosphate fertilizers. There is evidence that adding clovers to a crop solubilizes soil Cd, increasing the bioavailability of Cd. This can lead to high plant Cd concentrations. This research aimed to test whether liming-induced increases in pH in mixed crops of clovers and ryegrasses reduced forage Cd concentrations. A greenhouse pot trial applied lime at three rates (0, 1, and 2% of soil dry weight)...
