Na območju slovenske Istre v oljčniku sorte ˈItranaˈ na lokaciji Marezige je bil zasnovan poljski poskus za ovrednotenje vpliva uporabe oljčnih tropin na okolje. Poskus je vključeval pet obravnav: kontrola ─ brez dodatka tropin – zatravljeno – obravnava 1; oljčne tropine, dodane na površino tal spomladi – obravnava 2; oljčne tropine, dodane in zadelane v tla spomladi – obravnava 3; oljčne tropine dodane na površino tal jeseni – obravnava 4; oljčne tropine dodane in vdelane v tla jeseni * – obravnava 5.

Abstract:

Within the CRP V4-2216 project “Preservation and enhancement of soil productive potential for the sustainable cultivation of olives (GO-TO S-OIL)”, we aimed to evaluate the direct effects of the timing and method of applying olive pomace produced in Slovenian olive mills on soil properties, soil water, and plant nutrition. A field experiment was established in an olive orchard of the cultivar Itrana in Marezige (Slovene Istria) to assess the environmental impacts of olive pomace application. The experiment comprised five treatments: a control without pomace applied on managed grass cover (treatment 1); olive pomace applied to the soil surface in spring (treatment 2); olive pomace applied and incorporated into the soil in spring (treatment 3); olive pomace applied to the soil surface in autumn (treatment 4); and olive pomace applied and incorporated into the soil in autumn (treatment 5). The results showed that two-phase olive pomace is a valuable organic amendment, as it improves soil fertility and water retention. Its effect on soil pH depended on the initial soil acidity. Spring application of olive pomace may cause nutrient imbalances and nitrogen losses; therefore, autumn application is generally more suitable, as the risks of nutrient leaching and nitrogen immobilisation are lower during this period. Mechanical incorporation of olive pomace into the soil is recommended to reduce the risk of point-source contamination; however, in autumn, weather conditions may limit the feasibility of soil incorporation. For sustainable long-term use, continuous monitoring of heavy metals, particularly copper and zinc, is essential, as these elements may accumulate in the soil with repeated applications of olive pomace.
