Abstract:V zadnjih desetletjih se je pri gospodarjenju z gozdovi povečala uporaba težkih strojev, ki povzročajo zbijanje in spremembo morfologije tal. Ker je ranljivost tal na zbijanje močno odvisna od vrste tal in od trenutne vsebnosti vode v tleh, je za prakso velikega pomena hitra ocena primernosti razmer za uporabo mehanizacije. Članek tako obravnava hitre metode za določanje mehanskih lastnosti tal. Testirali smo metodo blatne kepe, ki smo jo nadgradili z oceno videza rok in odtisom rok med pripravo blatnih kep, meritvami vsebnosti vode in določanjem spodnje in zgornje meje plastičnosti tal. V raziskavo smo vključili pogoste talne tipe gozdnih rastišč v Sloveniji: pokarbonatna tla (eutric cambisol), distrična rjava tla (dystric cambisol) in hipoglej (eutric gleysol). Rezultati so pokazali, da se površina blatne kepe ob spustu na tla povečuje z vsebnostjo vode v vzorcu, sočasno pa se spreminjajo videz blatne kepe, umazanost in videz odtisa rok. Oceni videza in odtisa rok predstavljata dopolnitev obstoječe metode blatne kepe, lahko pa tudi njeno alternativo, saj ju lahko uporabimo samostojno. Z določitvijo spodnje in zgornje meje plastičnosti oziroma indeksa plastičnosti tal smo posredno ocenili tveganje za poškodbe tal pri gozdni proizvodnji. S pomočjo kazalnikov stanja tal, kot so videz blatne kepe, umazanost rok in videz odtisa rok, lahko v praksi preprosto in hitro ocenimo trenutne razmere za delo in s tem preprečimo prekomerne poškodbe tal med gozdno proizvodnjo.

Title:Assessment of the vulnerability of forest soils to compaction due to mechanization - testing and improving the field soil clump method
Abstract:In recent decades, the use of heavy machinery in forest management has increased, causing compaction and alternations in soil morphology. As soil vulnerability to compaction is highly dependent on the type of soil and the current soil water content, rapid assessment of the suitability of the conditions for the use of machinery is of great importance for practice. The article discusses methods for rapidly determining the mechanical properties of soil. We tested the soil clump method, which was supplemented by the assessment of the appearance of the hand and handprint during preparation of the soil clumps, soil water content measurements and determination of the lower and upper limits of soil plasticity. The following soil types, which are common in Slovenian forest stands, were selected: brown soil on limestone and dolomite (Eutric Cambisol), dystric brown soil (Dystric Cambisol) and hypogley (Eutric Gleysol). The results of the study showed that, when dropped, the surface area of the clump increases with the water content of the soil, while at the same time the appearance of the clump, the soil residue on the hands and the appearance of the handprint change. Evaluation of the appearance of the hands and handprint represent supplements to the existing clump method, but can also be an alternative to it, as they can be both used independently. By determining the lower and upper limits of plasticity or soil strength, we indirectly assessed the risk of soil damage in forest production. Through the use of soil condition indicators, such as the appearance of the soil clump, the soil residue on the hands and the appearance of the handprint, we can quickly and easily assess the current working conditions in practise and thus prevent excessive soil deformation in forest operations.
