Copper for crop production
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 …

COPPER
4.2 Plant Tissue Analysis The copper content of most plants is generally between 2 - 20 mg/kg Cu. For a wide variety of plants, copper deficiency occurs where copper levels are less than 5 mg/kg Cu in the leaf dry matter. Copper deficiency may also occur in grazing animals if the copper concentration in the pasture is below this concentration.

Assessment of heavy metal concentrations in roadside soils and plants
Addressing this gap, this study investigates soil contamination levels and heavy metal concentrations in dominant plants along a highway and railway in the vicinity of the Dexing Copper Mine, the largest open-pit copper mine in China, located in Jiangxi Province. These transportation routes are heavily utilized for ore transportation, making ...
Nutrient Content of Plants:
Young plants may contain 3.00 to 5.00 percent K, although the actual requirement may not be that high. Because it is mobile in the plant, K deficiency symptoms appear in the older plant tissue first. The K concentration in the plant decreases with age. Potassium balance in plants is important.
#113 Copper (Cu)
concentration of Cu in soil affects seed germination, root system development and plant vigor, but the amount of Cu needed to reach toxic levels depends on the plant species.
