Reliable estimations of soil physical quality provide
valuable information for the evaluation and advancement
of agricultural soil management strategies. In the agriculturally
highly productive Pannonian basin in Eastern Austria, little
emphasis has been placed on the determination of soil physical
quality and corresponding soil degradation risks. Nevertheless,
ongoing climate change, especially prolonged drought periods
and higher rainfall intensity, will raise the need for appropriate
soil management strategies. Soil physical quality was therefore
assessed in nine soil profiles in a long-term tillage experiment
which has been in operation since 1988 in Eastern Austria. Soil
samples from depths of between 2 and 37 cm and under three different
tillage systems (conventional, reduced and minimal tillage)
were analysed for various indicators of soil physical quality. The
resulting classifications of soil physical quality in the different
profiles were compared qualitatively and quantitatively together
with an estimation concerning the representativeness of the soil
physical quality indicators used. The outcomes showed severe soil
compaction under all tillage treatments and slight improvements
in soil physical quality marginally above the working depth for
the different treatments. Additionally, conversion to conservation
tillage led to less pronounced improvements in soil physical quality
under Pannonian conditions than have been reported in more
humid climates.
