Abstract

Skupna površina oljčnikov v zadnjih letih narašča, z njimi pa tudi količina oljčnega olja in stranskih proizvodov. Namen diplomskega dela je, da skladno z novo Uredbo o uporabi oljčnih tropin in rastlinske vode za gnojenje (Ur. l. RS, št. 10/22), ter s pregledom obstoječe literature preučimo smisel uporabe le-teh na kmetijskih zemljiščih. Nato sledi pregled vrst in količin odpadkov v oljarni glede na sistem predelave in ugotovitev potrebe po hranilih oljčnega drevesa. Gnojenje z oljčnimi tropinami predvsem poveča organsko maso v tleh, vsebuje veliko kalija in železa ter je koristno zlasti za trajne nasade. Gnojenje s kompostiranimi oljčnimi tropinami te lastnosti še poveča, a se glede na trenutno zakonodajo ne smejo uporabljati dlje od 14 dni. Uporaba rastlinske vode za gnojenje znatno pripomore k zmanjšanemu tveganju onesnaževanja okolja in je zelo uporabna za večanje rodovitnosti tal, vendar le pri strogem upoštevanju dovoljenih količin in časovnih omejitev. Uporaba obeh možnosti gnojenja je priporočena le ob predhodni analizi tal in njenih rezultatih. Potrebe oljke po hranilih so sicer večje kot jih lahko zadostimo z uporabo tropin in rastlinske vode, a je uporaba teh ekonomsko upravičena, preostanek hranil pa se lahko nadomesti z drugimi gnojili

Secondary title:	Use of olive processing residue for agricultural land fertilization
Secondary abstract:	The total area of olive groves has been increasing in recent years, and so has the volume of olive oil and its by-products. The aim of this thesis was to examine the rationale for using olive pomace and vegetable water for fertilisation, in accordance with the new Regulation on the use of olive pomace and vegetable water for fertilisation (Official Gazette of the RS, No 10/22), and to review the existing literature on the use of olive pomace and vegetable water on agricultural land. This is followed by an overview of the types and quantities of waste in the mill according to the processing system and an identification of the nutrient requirements of the olive tree. Fertilisation with olive pomace mainly increases the organic matter in the soil, is high in potassium and iron and is particularly beneficial for permanent crops. Fertilisation with composted olive pomace further increases these properties but, according to current legislation, should not be used for more than 14 days. The use of plant water for fertilisation contributes significantly to reducing the risk of environmental pollution and is very useful for increasing soil fertility, but only if the permitted amounts and time limits are strictly observed. The use of both fertilisation options is only recommended if the soil and the results have been analysed. Although the nutrient requirements of the olive tree are greater than can be met by the use of pomace and vegetable water, the use of these is economically viable, and the rest of the nutrients can be replaced by other fertilisers
