Uptake of heavy metals by ryegrass (Lolium multiflorum) in two soils of Rio Grande do Sul


, : Uptake of heavy metals by ryegrass (Lolium multiflorum) in two soils of Rio Grande do Sul. Pesquisa Agropecuaria Brasileira 30(10): 1217-1224

L. multiflorum was sown into pots containing yellow podzolic soils from 2 sites in Rio Grande do Sul and treated with 0, 5 or 8.5 g/kg of residue from an integrated waste water treatment plant. NPK was applied at sowing with further applications of N (as urea) at 4 and 8 weeks after sowing. During the 88-d trial, plants were cut 3 times.
