Otrazheny analiticheskie metody opredeleniya soderzhaniya mikroelementov i ikh biologicheskoe znachenie. Daetsya analiz soderzhaniya mikroelementov v pochvoobrazuyushchikh porodakh v zavisimosti ot uslovii ikh formirovaniya i granulometricheskogo sostava; formirovaniya biogeokhimicheskikh provintsiy. Opisany metody monitoringa, kartografirovaniya i gruppirovki pochv po soderzhaniyu podvizhnykh i nepodvizhnykh form mikroelementov, a takzhe soderzhanie i trasformatsiya mikroelementov v pochvakh. S uchetom novykh dannykh veterinarnoy nauki i praktiki v kratkoy forme izlozheny svedeniya o etiologiii, simptomatike, metodakh diagnostiki i differentsial'noy diagnostiki, a takzhe sposobakh lecheniya i profilaktiki endemicheskikh zabolevanii(mikroelementozov) zhivotnykh i rasteniy. V prilozhenii dany: - predel'no-dopustimye kontsentratsii khimicheskikh veshchestv v osadkakh stochnykh vod ispol'zuemykh dlya udobreniya, v pochve(podvizhnye formy), prodovol'stvennom syr'e i pishchevykh produktakh; - soderzhanie(urovni-parametry) mikroelementov v rastitel'nykh ob"ektakh, organizme, a takzhe sutochnye normy potrebleniya mikroelementov zhivotnymi. Rabota illyustrirovana i rasschitana dlya biologov, veterinarnykh spetsialistov, aspirantov i studentov vuzov.
