Abstract: The researches were conducted in three common alder monocultures, established by the deposition of the waste-rock fom the open-pits of the lignite mines. The total annual yield of the litterfall, organic carbon and nitrogen, phosphorous, and potassium was studied. The ratio C/N and the hydrolyzed nitrogen forms were determined. In the organic soil layers and surface layers of soil covered by the common alder the seasonal dynamics of the number od the saprophytic microorganisms, which have the important role in the nitrogen cycle in the forest ecosystems, was studied. Izvod: Istraživanja su izvršena u tri monokulture crne jove, podignutim na deposolima nastalim odlaganjem jalovine sa površinskih kopova rudnika lignita. Ispitivan je ukupan godišnji priliv lisnog opada, organskog ugljenika i azota, fosfora I kalijuma. Određen je C/N odnos i hidrolizujući oblici azota U organskoj prostirci I površinskim slojevima zemljišta pod kulturom jove ispitana je sezonska dinamika brojnosti saprofitnih mikroorganizama koji obavljaju važnu funkciju u kruženju azota u šumskim ekosistemima. https://unilib.phaidrabg.rs/o:9487 ISSN: 1821-1046 The microorganisms population size of the soil organic layer and characteristics of the litterfall of the common alder (alnus glutinosa gaertn.) on the reclaimed mine soil of miningenergy-industrial complex "Kolubara" Biogenost organske prostirke i karakteristike lisnog opada crne jove (alnus glutinosa gaertn.) na deposolima reik "Kolubara" MIletić, Zoran Čokeša, Vlado Stajić, Snežana Radulović, Zlatan Poduška, Zoran Matović, Bratislav info:eu-repo/semantics/article Sustainable forestry volume: 59-60 startpage: 19 endpage: 30 Key words: common alder, litterfall, organic soil layer, saprophytic microorganisms, plant assimilatives.
