o:6639 ISTRAŽIVANJE UTICAJA OKOPAVANJA I PRIHRANE MINERALNIM ĐUBRIVOM (NPK) NA RAZVOJ KULTURE BELOG BORA (PINUS SILVESTRIS L.) U IBARSKOJ KLISURI sr U teoretskom smislu, jedan od alternativnih postupaka za prevazilaženje problema pošumljavanja plitkih i skeletnih zemljišta na serpentinu bilo je okopavanje i đubrenje mladih kultura. U cilju ispitivanja ove mogućnosti postavljen je poljski ogled, sa četiri ponavljanja, u kulturi belog bora. Starost kulture bila je 1 godina, a starost sadnica 2 godine. Okopavanje i đubrenje sadnica izvršeno je u tri navrata - tokom maja meseca 1987, 1988. i 1989. godine. Rezultati istraživanja pokazuju da su primenjene mere nege imale pozitivan efekat na preživljavanje i razvoj sadnica. In the theoretical sense, one of alternative methods in overcoming the problem of afforestation of shallow and skeletal soil on serpentine was hoeing up and fertilization of young cultures. In order to explore this possibility, a field test was set in the culture of Scots pine, and repeated four times. The cultures were one year old, and the seedlings two years old. Hoeing and fertilization of seedlings were performed three times - during the month of May 1987, 1988. and 1989. The results of the research indicate that the applied measures had positive effect on the survival and development of seedlings. serpentin, pošumljavanje, beli bor, okopavanje, đubrenje serpentine, afforestation, Scots pine, hoeing, fertilization 1552101 0361-9147 2024-12-17T09:48:37.848Z 44 yes 46 Slavica Radojičić 46 Slobodan Šmit 46 Ljubinko Rakonjac 0000-0002-8736-6771 46 Vlado Čokeša 0000-0003-1940-2598 application/pdf 8737075 https://unilib.phaidrabg.rs/o:6639 no yes 1 70 92000001 1995 71A07 Zbornik radova Instituta za šumarstvo 17 28 Institut za šumarstvo 1995
