On the basis of reviews of more than 250 publications dealing with metal-soil-plant interaction, various controlling factors have been evaluated. Source of base metals, nature of soil formation and fractionation, and mobilization of metals in the soil profile, uptake limits by various plants, differing assimilation by different plants and different parts of a plant, etc. have been studied and the state of knowledge on the subject evaluated. Impact of metal pollution in the soil environment, physiological effect on plants, and factors contributing to uptake of individual metal from among a group of metals have been summarized. While extensive studies have been made on the micronutrient aspects of base metals in the soil environment, the literature survey revealed a wide gap in our knowledge on excess available base metals in the soil environment. Limited literature available on the subject clearly points out that metal pollution of plants will be the result of contamination of the soil environment. Finally, the literature survey clearly indicated scarcity of data on competition of metals for assimilation by plants. Since, in natural systems, metals always occur in “groups”;, extension of “culture”; data to field situation has not always been correct in the papers cited. |
