| Abstract/Contents: | "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) to eight different plant treatmentsfour as monocultures (perennial ryegrass [Lolium perenne L.], Italian ryegrass [L. multiflorum Lam.], white clover [Trifolium repens L.], and red clover [T. pratense L.]) and four as ryegrassclover mixtures (two plant types in each treatment)in soil (initial soil pH = 5.1, initial soil Cd concentration = 1.31 mg kg-1) with added Cd (CdSO4 ~ 1 mg kg-1). Adding lime increased soil pH in both mono- and mixed crops and, in most treatments, increased forage yields. However, the relationship between forage Cd and soil pH differed between plant treatments. In mono- and mixed crop treatments containing perennial ryegrass, adding lime increased the forage yield but did not increase the mass of Cd in the plants compared with the no-lime treatment. However, adding lime to treatments that included Italian ryegrass increased both the forage yield and the Cd compared with the no-lime treatment. The results show that a combination of certain plant species composition and lime rates can optimize forage yields without increasing forage Cd concentrations." |
