This study sets out to examine the effects of hedgerow shading on soil physical properties, specifically soil gravimetric water content and soil temperature. Analyses of both soil parameters were conducted at two locations with different shade proportion. The aim of the study was to address the links between hedgerow shading and basic physical soil properties which could be significant both for agricultural production and for ecological processes in agroecosystems. At both locations, soil samples and measurements were taken at different distances from hedgerow and in different time intervals. Diurnal shading variation at certain distances from the hedgerow on Location 1 and 2 was calculated with the software toll for Arboriculturists. At Location 1 shading is consistently high throughout the year, ranging from 76 to 100%. In contrast, shading at Location 2 varies from 1 to 25%. The results reveal that hedgerows at Location 1, do not have a statistically significant impact on gravimetric soil water content and soil temperature across the entire plot surface. Additionally, the percentage of shading is only marginally decreases with distance. Conversely, Location 2 exhibits an increase in soil temperature and a slight but (non-significant) decrease in soil gravimetric water content as the distance from the hedgerow increases., The total mean shading at Location 2 is considerably lower compared to Location 1, and the shading percentage declines more at the distance from the hedgerow increases. Overall, lower soil temperatures and higher gravimetric soil water content where observed at the more shaded Location 1. The research outcomes are helpful in agricultural production planning as well as in the evaluation of hedgerows for the needs of agricultural policy.

Sekundarni povzetek:	Študija obravnava učinek zasenčenosti zaradi mejic na fizikalne lastnosti tal: gravimetrično vsebnost vode v tleh in temperaturo tal. Analiza obeh parametrov je bila izvedena na dveh lokacijah, pri čemer je bila lokacija 1 iz dveh strani obdana z mejico, lokacija 2 pa z mejico le na eni strani. Vzorci tal in meritve temperature tal so bili odvzeti na različnih razdaljah od mejice in v različnih časovnih intervalih na obeh lokacijah. Dnevno zasenčenost na različnih razdaljah od mejice na lokaciji 1 in 2 smo izračunali s programom ArborShadow R4. Na lokaciji 1 je zasenčenost zelo visoka in se giblje od 76 do 100% skozi vse leto, na lokaciji 2 pa nižja in se giblje med 1 do 25%. Na lokaciji 1 je bilo ugotovljeno, da mejice nimajo statistično pomembnega vpliva na gravimetrično vsebnost vode v tleh ter temperaturo tal po celotni površini parcele, medtem ko se odstotek senčenja z razdaljo le rahlo zmanjšuje. Na lokaciji 2 je bilo ugotovljeno povišanje temperature tal in rahlo zmanjšanje (statistično neznačilno) gravimetrične vsebnosti vode v tleh z naraščajočo oddaljenostjo od mejice, medtem ko je skupna povprečna zasenčenost glede na lokacijo 1 precej nižja. Poleg tega na lokaciji 2 odstotek zasenčnosti močneje upada z oddaljenostjo od mejice. Na splošno je mogoče opaziti nižje temperature tal in višjo gravimetrično vsebnost vode v tleh na bolj zasenčeni lokaciji 1.
