Microelements in the agricultural landscapes of the Altai region

The aim of the study was to assess ecological, biogeochemical and sanitary-hygienic aspects arable soils Altai region spring wheat grain produced there. Location time study. representative sites land were located in various agroecological zones region: Kulundinskaya (dry steppe on chestnut Kulunda lowland), Rubtsovskoye (arid chernozems southern Priobskoye plateau), Zarinskaya (deciduous forests meadows leached Bie-Chumyshskaya elevated plain podzolized dark gray forest Salair Foothills), Piedmont (meadow Prealtai Plain), Priobskaya (split ordinary Priobsky Aleiskaya (moderately arid Biyskaya (forest Bie-Chumysh Upland). research carried out 2018. Methods. content trace elements determined by atomic emission absorption spectrometry according PND F 14.1:2:4. 139; 140-98; НСАМ №450С; РД 52.24.479-95. Results. It found that elements, necessary for plants, animals, humans, contained optimal quantities (average Mn 714, Zn 65, Cu 25.7, Co 12.3 mg/kg), maintaining normal functioning living organisms. Most toxic at levels, comparable with average concentrations world data uncontaminated West Siberia, not exceeding maximal permissible concentrations. Cd, Pb, As Hg studied 0.089, 13.6, 5.0, 0.037 mg/kg, respectively. No province had been identified any elements. have a fairly high buffering capacity heavy metals. chemical elements’ grain, main crop region, close corresponding grain. amount regulated substances (lead, cadmium, mercury, arsenic) meets domestic standards requirements Technical Regulations Customs Union "On Grain Safety". Conclusions. are contaminated Trace such as manganese, zinc, copper, cobalt However, using monofeed can result deficiency animals. is resulted from initial soil-forming parent rocks. degree metals’ soils, depending metal, ranged medium high.
