Treść
Tractor traffic leads to soil structure degradation which in turn results in unfavorable changes in the physical properties of soil. The lower porosity of soil and its air permeability impacts on the biological and chemical properties, including the availability of macro and micronutrients. Additional N input in soil supplies substrates in biological processes in soil. Thus, it could be expected that the combined effects of compaction and N fertilization are reflected in the chemical quality of the soil. The objective of the study was to determine the effect of multiple tractor passes and mineral N fertilization on the physical and chemical properties of soil under red clover/grass mixture. This study was conducted in a split-plot design, with fertilization as a main plot and compaction as a subplot. The N treatments used were: untreated control (N0), 80 kg N ha− 1 (N80) and 160 kg N ha− 1 (N160). Four compaction treatments were applied using the following number of tractor passes: untreated control (P0), two passes (P2), four passes (P4) and six passes (P6). The soil samples were collected on April 2010 and after the third harvest in October 2010, 2011 and 2012 and the physical parameters and chemical analysis were determined.
