Vpliv biooglja na kakovost tal in možnosti uporabe v gozdarstvu : diplomsko delo - univerzitetni študij - 1. stopnja = Biochar effects on soil quality and its potential use in forestry : B. Sc. Thesis - Academic Study ProgrammesHorvat, Peter, gozdarPregled literature o učinkih biooglja na kakovost tal je pokazal, da dodatek biooglja gozdnim tlem lahko prinaša številne koristi, kot je povečana vsebnost organske snovi, sposobnost zadrževanja vode ... in hranil (PK, CEC) ter obstojnost strukturnih agregatov. Potencialno je manj tveganja za erozijske procese in izpuste toplogrednih plinov. Raziskave vpliva biooglja na kalitev semen, kot tudi na rast sadik in dreves kažejo na povečan, zmanjšan ali nevtralen učinek. Učinki biooglja so odvisni tako od lastnosti, odmerka in aktivacije biooglja kot tudi od tipa tal in klimatskih razmer, ter vrste in vegetacijske faze izbrane rastline. V gozdarstvu bi bilo biooglje smiselno uporabljati kot dodatek tlem posebno na degradiranih območjih (tla z malo organske snovi, onesnažena tla), pri obnovi gozdov po ekoloških motnjah, ali sanacijo območij skladišč lesa, vlak in zapuščenih gozdnih cest. V eksperimentalnem delu naloge smo ugotovili, da je biooglje negativno vplivalo na kalitev semen pavlovnije (Paulownia tomentosa (Thunb.) Steud.), saj je pri dodatku biooglja vzklilo 12 % manj semen kot pri kontroli. Vendar pa je kasneje pozitivno vplivalo na rast klic, saj so bile v povprečju za 18 % večje v primerjavi s kontrolnimi brez dodanega biooglja. Pri lončnem poskusu, pričakovano do zaključka diplomske naloge, nismo ugotovili statistično značilnih razlik v višinski in debelinski rasti navadne bukve (Fagus sylvatica L.). Smo pa ugotovili značilne razlike v talnih lastnostih med obravnavanji. Dodatek biooglja tlem je povečal vsebnost organskega C (za 5,9 %), vodno-zadrževalne sposobnosti tal (za 12,3 % pri PK in za 7,8 % pri TV); ter CEC (za 6,0 mmolc/100g) v primerjavi s kontrolnimi tlemi.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [P.
