Abstract:V letu 2002 in 2003 smo na posestvu Fakultete za kmetijstvo in biosistemske vede (UKC Pohorski dvor) v ekološko oskrbovanem nasadu jablan sorte Topaz z gostoto 4081 drevesi na hektar, v mladostnem obdobju, preiskušali vpliv gnojenja z organskimi gnojili (Compo guano, Maltaflor special, Agrovit in Biosol) na količino mineralnega dušika v različnih globinah tal. Hkrati smo preučili vpliv obdelave tal (obdelana tla in kombinirana obdelava) na mineralizacijo. Poskus je bil zasnovan v naključnih blokih, gnojenje je bil izvedeno v 1 m širokem pasu pod drevesi s 44 kg čistega dušika preračunano na hektar. V letu 2002 so bile pri zgodnji obdelavi tal (17. aprila) višje vrednosti mineralnega dušika v odvzetih vzorcih v maju 2002 kot pri kasnejši obdelavi, ki je bila opravljena 6. maja. V istem letu je bil močno izražen vpliv ekoloških faktorjev na nivo mineralnega dušika v tleh. Nadpovprečno visoke temperature in pomanjkanje padavin je povzročilo šibko mineralizacijo. Ob pojavu padavin, so se dvignile N-min vrednosti pri obeh načinih obdelave ter vseh uporabljenih gnojilih.

Title:THE INFLUENCE OF FERTILIZATION WITH ORGANIC FERTILIZERS AND SOIL CULTIVATION ON AMOUND OF MINERAL NITROGEN IN SOIL IN ORGANIC APPLE PRODUCTION CV. TOPAZ
Abstract:In the year 2002 and 2003 we were on the estate of Faculty of Agriculture and life sciences (UKC Pohorje court) in organically supplied plantation of apple trees of variety Topaz with density 4081 trees per hectare, in youthful period, determined influence of fertilising with organic fertilizers (Compo guano, Maltaflor special, Agrovit and Biosol) on amount of mineral nitrogen in different depths of ground. We investigated influence of treatment of ground at the same time (treated ground and combined treatment) on mineralization. Experiment was conceived in random blocks, fertilizing was versed in 1meter wide zone under trees with 44 kilograms of pure nitrogen calculated per hectare. They were, at early treatment of ground in the year 2002 (17th in April), more highly values of mineral nitrogen in taken away samples in May 2002 as at later treatment, which was completed on May 6. The influence of ecological factors on level of mineral nitrogen in ground was expressed strongly in the same year. More than averagely high temperatures and lack of precipitations caused weak mineralization. At appearance of precipitations, N-mines of value at both manners of treatment and all used fertilizers lifted.
