metals tested The tolerance of clone no 4 to copper has already been described (Hogan, 1975 ; Hogan et al, 1977) and is related to high levels of copper in its native soil, as well as a low soil pH, which serves to increase the availability of the metal Since this site is contaminated with high levels of nickel (244 mmol kg—I, Hogan et al.
Copper (Cu) is one of eight essential plant micronutrients Copper is required for many enzymatic activities in plants and for chlorophyll and seed production Deficiency of copper can lead to increased susceptibility to diseases like ergot, which can cause significant yield loss in small grains Most Minnesota soils supply adequate amounts of copper for crop production However, copper .
High soluble salt concentrations can also cause toxic amounts of some ions such as boron, chloride, sodium, and sulfate to accumulate in the plant Plant species vary widely in their tolerance to salts in soil and irrigation water In most plants, salt tolerance is lowest at ,

Copper concentrations were less in E+ than in E- plants (Dennis et al, 1998), with deficiency expressed as decreased Cu-related immune function (Saker et al, 1998) Cattle grazing E+ tall fescue showed symptoms of deficiency (coat condition and hair color) by the end of the grazing season in Kansas (Coffey et al, 1992) Copper concentrations in KY-31 tall fescue grown in
High levels of copper are found in liver, kidneys, brain, bones, and cornea of patients with Wilson's disease (a genetic disorder characterized by impaired copper metabolism) and in the liver of patients with primary biliary cirrhosis, cholestasis, and Indian childhood cirrhosis (Stokinger, 1981; ,
Ingestion of certain plants such as subterranean clover (Trifolium subterraneum), cause a mineral imbalance and excessive copper retention, resulting in chronic copper toxicosis (phytogenous toxicosis)The ingestion of plants such as Heliotropium europaeum or Senecio spp for several months may cause hepatogenous chronic copper toxicosis These plants (with normal concentrations of copper ,
