“…The most important factors affecting metal availability are soil pH, clay content and organic matter content (Anderson and Christensen 1988;McGrath et al 1988;Davies 1989;Alloway 1990;Kabata-Pendias and Pendias 1992).…”

The main purpose of this research was to determine the levels of heavy metals in tomato, potato and lettuce, grown in agricultural soils of different soil orders (Alfisols, Endisols and Vertisols), located at Central Greece. Soil samples were analysed for available forms (after extraction with DTPA) and for total concentrations (after digestion with Aqua Regia) of metals. Zn, Cu, Cr and Ni were the common metals detected in the vegetables studied. Pb and Cd concentrations were low and in some cases not detectable. Significant correlations among metals concentrations and soil physicochemical parameters were obtained and discussed. The pH value and the percentage of clay content were found to determine the solubility of metals in the soil and their availability for uptake by plants.

“…The availability for uptake by plant roots may differ between metals bound in soluble complexes and "free" metals. As organic materials influence the binding of heavy metals in soil and speciation in soil solution (Ram and Verloo 1985;McGrath et al 1988;Lo et al 1992;Del Castillho et al 1993), it may also affect plant uptake (Haghiri 1974;McBride et al 1981). Soil pH is another factor influencing the bioavailability of metals, both in terms of sorption in the soil and speciation in the soil solution.…”

. 1998. Plant uptake and DTPA-extractability of Cd, Cu, Ni and Zn in a Norwegian alum shale soil as affected by previous addition of dairy and pig manures and peat. Can. J. Soil Sci. 78: 531-539. Residual effects of cow manure, pig manure and peat soil on the DTPA-extractability and plant uptake of cadmium, copper, nickel and zinc were investigated in the second and third years after application to an alum shale soil. Wheat and barley were grown in alternate years. The effects of the organic matter applied differed among metals, sources of organic matter and time after application. The Cd concentrations in grain was reduced by the rates of peat soil, whereas the manures had no significant effect. Copper concentrations in grain and Zn concentrations in both grain and straw generally increased with rates of organic matter. Nickel concentration in grain tended to decrease with increasing rates of cow and pig manure applied, whereas it tended to increase with the addition of peat soil.The concentrations of DTPA-extractable metals in the soil were generally higher in the second and third years than in the first year after application of organic matter. Some of the metals bound by organic matter in the first year were probably released as the organic matter was decomposed. Decreases in DTPA-extractable Cd and Ni were found by the addition of pig and cow manure, whereas these manures resulted in increased DTPA-extractable Zn. The application of peat soil, on the other hand, resulted in increased amounts of DTPA-extractable Cu, Zn and Ni, probably due to decreased soil pH. o. Les concentrations de nickel dans le grain manifestaient une tendance à la baisse en fonction de l'accroissement des doses des apports de fumier, et à la hausse en fonction des apports de tourbe. Les concentrations de métaux extractibles au DTPA dans le sol étaient généralement plus élevées dans les deuxième et troisième années que dans l'année d'épandage de la matière organique. Certains des métaux liés par la m.o. dans la première année étaient vraisemblablement relargués à mesure que la m.o. se décomposait. Des baisses de Cd et de Ni extractibles au DTPA étaient observées après épandage de fumier de porc ou de vache, l'inverse s'observant pour le Zn. En revanche, l'apport de tourbe se traduisait par une augmentation des concentrations extractibles des trois métaux, probablement reliée à l' abaissement du pH du sol.

“…The above mentioned data agreed with those of Kiekens (1983) who found that, the presence of some cations (positive ions) in the soil solution such as Ca 2 + and Mg 2 + compete with cations of heavy metals efficiently and prevent It from adhering with plasma of plant tissues and subsequently their accumulation decrease. On the other hand, the addition of limestone to the soil works to reduce soil acidity and increase alkalinity and high pH of the soil solution and thus make heavy metals in the form that they are nonavailable for absorption in the root and accumulation within plant tissues (McGrath et al, 1988). The contents of total available sugars increased in all heavy metal-treated common bean plants except for lead.…”
