Role of Copper in Microbial growth: Used in electron transport. Back

Copper in the Soil Form taken up by the plant: Cu 2+ Mobility in the soil: Immobile, pH dependent, forms strong complexes with organic matter, oxides of Fe, Al, Mn, phenolic carboxyl and hydroxyl groups, and clay minerals. Undergoes specific adsorption. Can be isomorphically substituted for Fe or Mn. Cu can leach through the soil profile in humus-poor, acidic peat, or in very acidic mineral soils, such as those around Ni and Cu smelters. Concentrations of natural Cu in soil is 34 t0 55 ppm. HomeNext

Copper in the Soil Interactions with other nutrients: Nitrogen and phosphorus (especially where Cu deficiencies exist), sulfur, iron, zinc, manganese, and molybdenum Effect of pH on availability: –high pH (> 7.0) Formation of hydrolysis products which adsorb to exchange sites (lower availability), CuOH + is the primary form. –middle pH ( ) Predominate form is Cu(OH) 2 0. –low pH (< 6.0) Exchange sites taken up by Al 3+ and H + allowing the Cu 2+ form to remain soluble.

Fertilizer sources: Copper sulfate, copper nitrate, copper chelate, copper ammonium phosphate, copper carbonate, animal waste, copper hydroxide, copper acetate, copper oxalate, copper oxychloride, copper polyflavanoids, copper-sulfur frits, copper- glass fusions, chalcanthite, azurite, malachite, chalcopyrite, chalcocite, covellite, tenorite, cuprite (Loneragan, 1998) Pesticide uses: Kopertox, Kocide, Bordeaux mixture, copper sulfate, copper chlorides, cupric hydroxide, copper oxides, miscellaneous other copper sources Home

Copper in Plants Form taken up by the plant: Cu 2+ Mobility in the plant: Immobile Concentration in plants: 2-30 ppm dry weight (Adriano, 1986); 5-20 ppm (Tisdale, 1985) Role of nutrient in plant growth: Copper can not be replaced by another metal ion in its involvement in enzymes. It is required for synthesis of quinones in chloroplasts, and makes up the electron transporter, plastocyanin in photosystem II. HomeNext

Copper in Plants Deficiency symptoms: Stunted growth, terminal dieback first in young shoots, necrosis of the apical meristem, bleaching of young leaves, impaired lignification of cell wall, impaired pollen formation and fertilization, delayed flowering and maturation, shortened internodes, stem deformation, yellowing, curling of leaves, seed and fruit growth dramatically reduced Toxicity symptoms: Stunting, reduced shoot vigor, reduced branching, thickening, poorly developed and discolored roots, leaf chlorosis resemble Fe defiencies BackNext

Copper in Plants Enzymes containing Cu: Superoxide Dismutase (CuZnSOD), Cytochrome oxidase, Ascorbate oxidase, Phenol oxidase, Trysinase, Laccase, Diamine oxidase, Plastocyanine, Amine oxidase, Stellacyanin Copper tolerance: binding to cell wall, restricted influx through plasma membrane, active efflux, compartmentation in vacuole, chelation at the cell wall-plasma membrane interface, chelation in the cytoplasm HomeBack

Copper in Animals Tissue distribution: –highest concentrations liver, kidneys, heart, pigmented part of the eye, and hair or wool –mediumconcentrations pancreas, spleen, muscles, skin and bone –lowest concentrations thyroid, pituitary, and thymus Transport and tissue utilization: Cu is loosely bound to plasma albumin and is distributed to the tissues and taken up by the bone marrow in red blood cell formation. Home Next

Copper in Animals Functions: activity of enzymes associated with Fe metabolism, elastin and collagen formation, melanin production, integrity of the central nervous system, red blood cell formation (hematopoiesis), lysyl oxidase, cytochrome c oxidase, ferroxidase, tyrosinase, normal hair and wool pigmentation (polyphenyl oxidase), incorporation of disulfide groups into keratin in wool and hair Next Back

Copper in Animals Absorption: Absorption is species dependent mainly from the jejunum, duodenum, small intestine, or colon. Excretion: Bile is the major pathway. Smaller amounts are lost in feces, urine, and sweat. Deficiency signs: decline in tissue and blood Cu concentration, incoordination, ataxia, bone abnormalities, hair and wool fail to develop normally, cardiovascular lesions and hemorrhages, fetal death Next Back

Copper in Animals Toxicity: Sheep and calves appear to be more susceptible to Cu toxicity than other species. Observations include hemoglobinuria, jaundice, and tissue necrosis. Toxic to sheep when Cu:Mo ratio >10:1. Back Home
