mechanisms underlying such high-level tolerance are largely metal specific (Schat and Vooijs, 1997). High-level copper tolerance in S. vulgaris, as suggested by the segregation patterns in crosses between plants from copper-sensitive and copper-tolerant popula-tions, may be controlled by two primary tolerance

Copper - To Much or Too Little? - GoatWorld Articles ...

One of the most widely mis-understood facets of raising goats is how much copper they require. Since I began raising goats full-time approximately four years ago, much re-thinking of this issue has occured. For one thing, 4 years ago people were under the presumption that too much copper was a bad thing and steered clear of pre-mixed feeds that contained high levels of copper.

Copper and Soil Fertility - USDA

Copper and Soil Fertility Walter Reuther Soils high in organic matter and weathered, sandy soils are likely to be deficient in copper. A great deficiency may cause serious stunting of growth and visible symptoms of disease in plants, but moderate deficiency may merely reduce yields. Copper once was regarded as a plant
