The field experiment was carried out on a smoothstalked
meadow-grass to analyse the effect of tractor traffic on
herbage production and root morphology. The multiple passes of
tractor changed physical properties of soil. Increase in bulk density
and penetration resistance of soil under smooth-stalked meadowgrass
was recorded up to the depth of 30 cm. The tractor traffic resulted
in changes in smooth-stalked meadow-grass yields. During
the second and the third harvest it was found that wheel traffic decreased
plant yields. For the first harvest the opposite effect in
herbage production was noticed. The tractor traffic significantly
changed the root morphometric properties in the upper, 0-5 cm,
soil layer. Intensive tractor traffic (four and six passes) significantly
increased the root length in diameter range of 0.1-0.5 mm.
There were no differences in both mean root diameter and specific
root length what indicated that traffic treatment applied did not
change the root diameter. The results indicate that smooth-stalked
meadow-grass could be recommended for compacted soils when
intensive traffic is present.
