ALLMANOVA ZUZANA, MESSINGEROVA VALERIA, JANKOVSKÝ MARTIN. 2014. Soil Compaction and Changes in CO 2 Content in Forest Stand Soil Caused by Passage of Skidding Technology. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 62(1): 7-16. The paper was aimed on reforming on damage to soil caused by passage of universal wheeled tractors and forest wheeled tractors. We focused mainly on determining the changes in CO 2 content in soil aer its compaction in comparison with unimpaired soil from the stand. We carried out the measurements in municipal forests of Stara Tura, in four stands, where a regeneration felling was done. We acquired data on the depth of ruts through the method of transversal profi les took samples of soil from the ruts and unimpaired stand to determine the bulk density and moisture content. We determined the content of CO 2 in stand and ruts with a Vaisala MI70 device. We selected the stands so that they would be uniform in age, terrain incline, terrain, and soil type. All of the stands had a low bearing sub - soils - fl ysch sandstone. This aff ected the rut depth aer both machines passage. Rut depth indicated severe damage to the stand soil. We also observed severe diff erences in CO 2 content of the compacted soil. Measurements in all of the stands showed a signifi cant increase in CO 2 content aer its compression. Unimpaired soil reaches volume of 0.3% and rut soil reaches 1.8%. The compressed soils contained 6x the CO 2 of uncompressed soils. The results of statistical analysis show, that moisture content aff ects the CO 2 content more than bulk density. Coefi cients of correlation between CO 2 and moisture content were r = 0.68 and 0.52 and between CO 2 and balk density were r = 0.26 and 0.36. Increase in moisture content causes CO 2 accumulation. Combined eff ects of these two characteristics are signifi cant and show very strong correlation. There was for example r = 0.83 and independent characteristics infl uenced dependent on 69%. From the outcomes the measurements we can state, that the passage of mechanisms causes signifi cant changes in the stand soil.
