Treść
Tractor traffic and related soil compaction may create unfavourable growing conditions for the development of roots and above-ground biomass production. It can be expected that higher N fertilization and higher below-ground biomass production can remediate soil physically degraded by wheel compaction. The main objective of this study was to investigate the interaction between tractor traffic and N fertilization of a clover/grass mixture during the period from 2010 to 2012. The experiment was established in a split-plot design with fertilization as a main plot and tractor passes as a subplot. The N fertilizer 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 numbers of tractor passes: untreated control (P0), two passes (P2), four passes (P4) and six passes (P6). Root samples were collected in the autumn of 2010, 2011 and 2012 and their morphometric parameters were calculated after measurement of the root length, using image analysis: root length density (RLD), mean root diameter (MRD), specific root length (SRL) and root dry matter (RDM).
