Impact of Soil Compaction on Bulk Density and Root Biomass of Quercus petraea L. at Reclaimed Post-Lignite Mining Site in Lusatia, Germany

Table 1

Bulk density of compacted and uncompacted postmining soils at different depths under Quercus petraea L. plantation.

Depth [cm]	Bulk density [g cm^−3]
	20–25	100–105	200–205
Compacted soils	1.74 ± 0.09	1.65 ± 0.06	1.62 ± 0.12
Uncompacted soils	1.56 ± 0.11	1.59 ± 0.06	1.56 ± 0.10

Different uppercase letters for the same column indicate significant difference in bulk density between compacted and uncompacted soils for a given depth; different lowercase letters as superscript on the same row indicate significant difference in bulk density within soil profile of compacted and uncompacted soils (Fisher LSD Method at ). Values are means ± standard deviation.
