Abstract
Liming at 0, 2.2, and 4.4 tons/hectare (0, 1, and 2 English tons/acre) was tested as a means of reducing Pb uptake by five species from two Pb contaminated soils. The soils represent the 0‐ to 10‐ and 10‐ to 30‐cm horizons of Los Osos clay loam (a Typic Argixeroll) and contained 94 ± 18 and 32 ± 7 ppm Pb, respectively. There was no effect of lime on yield, but Pb concentrations in tops were reduced. At all times of harvest and lime rates the Pb concentration followed the series Glycine max L. ≫ Trifolium subterraneum L. > Zea mays L. = Avena sativa L. = Triticum aestivum L.Keywords
