“…Concentrations of Olsen P, N-NO 3 and exchangeable Ca were much lower than those characterizing agricultural soils (Barker and Bryson, 2007;Morari et al, 2008) and, generally, lower than the concentrations in soils developed on waste produced by the coal industry (Dutta and Agrawal, 2001;Juwarkar and Jambhulkar, 2008;Woch et al, 2013) or in soils affected by metal ore mining and smelting (Álvarez et al, 2003;Lorenc-Pluci nska et al, 2013;Stefanowicz et al, 2012). Only amounts of exchangeable K and N-NH 4 were similar, or higher, compared with the values recorded for soils of other industrial sites Dutta and Agrawal, 2001;LorencPluci nska et al, 2013;Mummey et al, 2002;Stefanowicz et al, 2012;Woch et al, 2013).…”

“…In our study, microbial catabolic activity measured by MicroResp™ was strengthened in the sub-layer rhizospheric soils due to the growth of S. alfredii, which was consistent with some previous studies. For example, Stefanowicz et al (2012) showed that in metal-polluted soil, plants positively affected soil functional richness and apparently counteracted the toxic effects of metal contamination. Similarly, Epelde et al (2010) reported that T. caerulescens growth increased the substrate-induced respiration rates in the Zn-and Cd-contaminated soil.…”

The recovery of microbial community and activities is crucial to the remediation of contaminated soils. Distance-dependent variations of microbial community composition and metabolic characteristics in the rhizospheric soil of hyperaccumulator during phytoextraction are poorly understood. A 12-month phytoextraction experiment with Sedum alfredii in a Cd-contaminated soil was conducted. A pre-stratified rhizobox was used for separating sub-layer rhizospheric (0-2, 2-4, 4-6, 6-8, 8-10 mm from the root mat)/bulk soils. Soil microbial structure and function were analyzed by phospholipid fatty acid (PLFA) and MicroResp™ methods. The concentrations of total and specified PLFA biomarkers and the utilization rates for the 14 substrates (organic carbon) in the 0-2-mm sub-layer rhizospheric soil were significantly increased, as well as decreased with the increase in the distance from the root mat. Microbial structure measured by the ratios of different groups of PLFAs such as fungal/bacterial, monounsaturated/saturated, ratios of Gram-positive to Gram-negative (GP/GN) bacterial, and cyclopropyl/monoenoic precursors and 19:0 cyclo/18:1ω7c were significantly changed in the 0-2-mm soil. The PLFA contents and substrate utilization rates were negatively correlated with pH and total, acid-soluble, and reducible fractions of Cd, while positively correlated with labile carbon. The dynamics of microbial community were likely due to root exudates and Cd uptake by S. alfredii. This study revealed the stimulations and gradient changes of rhizosphere microbial community through phytoextraction, as reduced Cd concentration, pH, and increased labile carbons are due to the microbial community responses.

“…Under the project, the abundance of several groups of soil mesofauna and the structure and activity of soil microbial communities were determined (Kapusta et al, 2011;Stefanowicz et al, 2010;Stefanowicz et al 2012). The data were collected in a number of sites located so as to represent different types of substratum (carbonate rock, including metal-rich carbonate mining waste, and siliceous sand), different methods of land management (e.g.…”
