Enzyme activity as an indicator of soil-rehabilitation processes at a zinc and lead ore mining and processing area

Effects of regenerating vegetation on soil enzyme activity and microbial structure in reclaimed soils on a surface coal mine site

“…High soil concentrations of organic matter in the reclaimed treatments resulted to enzyme activities increasing (Table 3), and we also observed that soil enzyme activities were positively correlated with SOC, TN and AVN (Table 5). This is in accordance with those of Ciarkowska et al (2014), who found the high variability of SOC and TN in the examined soil samples was reflected by the large differences in enzyme activities and the enzyme activities were positively correlated with the carbon and nitrogen concentrations. During spontaneous succession in spoil heaps after brown coal mining, the major determinants of enzyme activity were the contents of SOC and TN in topsoil layer (Baldrian et al, 2008).…”

“…Soil enzyme activities integrate information about microbial status and soil physicochemical conditions (Aon and Colaneri, 2001;Sinsabaugh et al, 2010), and are indicators of the functioning of soil ecosystems (Ciarkowska et al, 2014). They have been similarly used in studies on the effectiveness of reclaimed treatments on soil quality (Li et al, 2012;Schimann et al, 2012;Finkenbein et al, 2013;Ciarkowska et al, 2014).…”

The activity of acid phosphatase may be a useful bioindicator for monitoring soil quality of acid, Pdeficient substrates from subtropical surface coal mines (Finkenbein et al, 2013), and urease and invertase activities can be used as progress indicators for soil-rehabilitation processes in industrial areas (Ciarkowska et al, 2014).…”

Soil enzyme activities were improved by applying weathered coals in reclaimed opencastmining areas of the Loess Plateau of China (Li et al, 2012).…”

“…Soil enzyme activities and microbial properties have increasingly been used indicators of soil quality to evaluate the success of reclamation efforts (Ciarkowska et al, 2014;Li et al, 2013bSchimann et al, 2012. For the Loess Plateau of China, there are few studies on the use of soil enzyme and microbe to assess the success of reclamation in surface coal mines treated with various amendments (Li et al, 2012;Li et al, 2012).…”
