V magistrski nalogi smo analizirali učinke zelenih protivetrnih pregrad (ZPP) v Vipavski dolini v odvisnosti od njihove višine in starosti na izbrane lastnosti okolja ter izbrane lastnosti posevka koruze (Zea mays). Analize so potekale na treh njivah, in sicer B (brez ZPP), N (nizka ZPP) in V (visoka ZPP) in na poskusnem nasadu, starem štiri leta. Analizirali smo vetrne razmere pred in za ZZP na njivi V in poskusnem nasadu ter preverjali učinkovitost zmanjšanja burje za ZPP. Primerjali smo vsebnost vode v tleh, kakovost in količino pridelka ter vsebnost ogljika v tleh med njivami in v odvisnosti od oddaljenosti od ZPP. Ugotovili smo, da se v povprečju zmanjša hitrost burje za ZPP za 88,12 % na 2,6H in za 55,48 % na 5,3H, kjer je H višina ZPP ob dani njivi. Vsebnost vode se ni razlikovala glede na oddaljenost od ZPP. Pozitiven vpliv smo zaznali na parametrih rasti in predelku koruze, saj so bili rezultati boljši na njivi V kot na njivi B. Z rezultati raziskave smo potrdili številne pozitivne vplive ZPP in nismo uspeli pokazati negativnih učinkov na ekosistemske storitve. Lahko potrdimo, da so ZPP pomemben strukturni element in naravna rešitev za varstvo in ohranjanje rodovitnosti kmetijskih površin v Vipavski dolini.

• Title: The effects of green windbreaks in the Vipava Valley on selected environmental factors and the growth of maize

Abstract

This master’s thesis analyses the effects of green windbreaks (GWB) in the Vipava Valley, focusing on their height and age, on selected environmental parameters and maize (Zea mays) crop characteristics. Research was conducted on three fields: B (without GWB), N (low GWB), and V (high GWB), as well as on a 4-year-old experimental plantation. Wind conditions before and after the GWB were measured in field V and in the plantation to assess their efficiency in reducing the burja wind. Soil water content, yield quantity and quality, and soil carbon content were compared between fields and at varying distances from the GWB. Results showed that burja wind speed was reduced on average by 88.12 % at 2,6H and 55,48 % at 5,3H behind the GWB, where H is the height of the GWB for the given field. Soil water content showed no significant differences with distance, but maize growth and yield were higher in fields with GWB than without. The findings confirm multiple positive effects of GWB, with no detected negative impacts on ecosystem services. GWB are an important structural element and a nature-based solution for protecting and preserving the fertility of agricultural land in the Vipava Valley.
