Biogeochemical Mapping of the South Ural Region, Russia

Chemical dements Distribution of sub-regions and biogeo-chemical provinces Content of dements in biogeochemical food webs Biological reactions of organisms and endemic diseases 

Co deficit Everywhere Low content of Co in Podsoluvisols, Podzols, Arenosols and Histosols. The average Co content in plant species is 5 ppb. The decrease of Co content in tissues decrease of vitamin Bi2 in liver (ir.-130ppm), in tissue (tr.-0,05 ppm), in milk (tr.-3ppm). Synthesis of vitamin Bi2 and protein is weakened. Cobalt-deficiency and B12 vitamin-deficiency. The number of animal diseases is decreasing in raw sheep — cattle - pigs and horses. Low meat and wool productivity and reproduction. 

Cu deficit Everywhere, but especially in Histosols Low content of Cu in Podsoluvisols, Podzols, Arenosols and Histosols. The 30% of forage samples contents Cu 3 ppm. The 3-fold reduction of Cu content in blood, 30-40-fold, in liver n X 10-fold increase of Fe in liver. The synthesis of oxidation ferments is depressed. The anemia of sheep and cattle was shown. 

Cu + Co deficit Especially in Swamp ecosystems Low content of Cu and Co in Podsoluvisols, Podzols, Arenosols and Histosols, Declining contents of Cu and Co in forage species (Cu from 3 to 0.7 ppm, Co 5 ppb) Depressed synthesis of B12 vitamin and oxidation ferments, Cobalt-deficiency and Bi2 vitamin-deficiency complicated by Cu deficiency. The prevalent diseases of sheep and cattle.
