Abstract

Kmetijska zemljišča na območju Slovenije se soočajo z naraščajočimi obremenitvami. V magistrskem delu smo preučevali raznolikost talnih organizmov v različnih kmetijskih sistemih (sadovnjak, nasad jagod in njiva) z različnimi metodami pridelave (ekološki/konvencionalni, različni sistemi obdelave tal). Cilj je bil oceniti in primerjati te sisteme na podlagi raznolikosti izbranih skupin živali v tleh in indeksa biološke kakovosti tal (QBS), pri čemer smo za analizo uvedli nov indeks QBS-a. Domnevali smo, da bomo v različnih sistemih kmetovanja opazili razlike v vrstni pestrosti in vrednosti indeksov ter pričakovali višje vrednosti v sistemih, ki izvajajo manj intenzivne kmetijske prakse. Napovedali smo najmanjšo velikost vzorca, ki je potrebna za natančno oceno raznovrstnosti talnih organizmov pri različnih vrstah kmetovanja in obdelave tal. Ugotovili smo, da na preučevanih kmetijskih površinah prevladujeta podrazreda Acarina (pršice) in Collembola (skakači), ki predstavljata 92 % vseh najdenih organizmov. Številčnost pedofavne se razlikuje med kmetijskimi sistemi, pri čemer je največja opažena na njivi. Potrdili smo višjo biološko kakovost tal pri ekološki pridelavi in pri manj intenzivnih praksah upravljanja s tlemi. Postavili smo smernice za optimizacijo strategij vzorčenja za oceno biotske raznovrstnosti v različnih kmetijskih sistemih, pri čemer poudarjamo potencial za učinkovitejše vzorčenje v prihodnosti.

Secondary title: Variability of soil animal community in agroecosystems of Slovenia
Secondary abstract: Slovenia's agricultural lands are experiencing increasing strains. In this master thesis, we analyzed the diversity of soil organisms across various farming systems (orchard, strawberry plantation, and arable field) and cultivation methods (organic/conventional, different soil tillage systems). The objective was to assess and compare these systems based on diversity of selected soil animal groups and the Soil Biological Quality Index (QBS), introducing a new index, QBS-a, for analysis. We hypothesized significant disparities in species diversity and index values across different farming systems, with expectations of higher values in systems practicing less intensive agricultural practices. We also predicted variability in the minimum sample size required for accurate soil organism diversity assessments across the different types of farming and tillage. We found out that in analyzed agricultural systems subclasses Acarina (mites) and Collembola (springtails) dominate the samples, constituting 92 % of all organisms found. Pedofauna abundance varies between agricultural systems, with the highest abundance noted in arable fields. We confirmed enhanced biological soil quality under organic production and less intensive soil management practices. We provided guidance on optimizing sampling strategies for biodiversity assessment in various agricultural systems, highlighting the potential for more efficient resource use in the future.
