Biological properties of soils on mine tips

Enzyme Activity as an Indicator of Soil Quality in Sterile Waste Heap

“…Kujur and Patel, 2012 determinated invertase activity 2.261±0.077 mg sucrose/g/h on coal mine overburden spoils in India (Kujur and Patel, 2012). The results obtained are similar to those reported by Naprasnikova which determine the enzyme activity of the invertase between 0.6 mg glucose/g for a 1 year waste heap and 10.1 mg glucose/g for a 10 year waste heap (Naprasnikova, 2008). The increase in enzyme activity with the age of heaps was also reported in other studies Baldrian, 2008).…”

“…In a paper that studies comparatively the enzymatic activity of soils in coal mines, stockpiled soil and an adjacent undisturbed soil, was determined a urease activity of 205 μg/g/day, 563 μg/g/day and 834 μg/g/day respectively (Fresquez et al, 1985). Naprasnikova in a paper presenting biological properties of soil forming on coalmine spoils of different ages in the area of Kansk-Achinsk coal basin reports for urease values of 2 mg NH 3 /10 g soil (1-3 years), 0.5-2.6 mg NH 3 /10 g soil (3-5 years) and 2.6-7.6 mg NH 3 /10 g soil (5-10 years) (Naprasnikova, 2008). Phosphatase (EC 3.1.3.2) is an enzyme that plays a key role in the hydrolysis of organic phosphorus compounds in the soil resulting in inorganic phosphate in accessible forms that support plant growth and development.…”

“…The waste heap will undergo complex and long-term biological processes, transformation, accumulation of an organic material, occurrence of the activity of microorganisms similar to soil pedogenesis. Recent research has shown that in the processes of evolution of waste material from the heap to agricultural soil a key role is played by enzymatic activity in the soil (Naprasnikova, 2008). Soil enzymes may derive from microbial and plant sources as intracellular enzymes, extracellular soluble enzymes and enzymes complexed with clays and organic matter (Popa A et al, 2005).…”

Pedogenesis problems on reclaimed coal mining sites

“…Nowadays, the trends are more in favour of spontaneous and directed succession and biodiversity preservation (Brenner et al 1984;Wiegleb & Felinks 2001;Hodačová & Prach 2003;Frouz & Nováková 2005;Mohr et al 2005;Šourková et al 2005a;Frouz et al 2007b;Hendrychová 2008;Helingerová et al 2010;Řehounková et al 2011;Brom et al 2012;Tropek et al 2012;Chuman 2015). Many, both successful and unsuccessful mine reclamations, have been described all over the world (Bradshaw & Hüttl 2001), including USA (Brenner 1979;Zellmer & Wilkey 1979;Brenner et al 1984;Mummey et al 2002a, b;Lorenz & Lal 2007;Anderson et al 2008;Shrestha & Lal 2008;Lanham et al 2015), Australia (Bell 2001), India (Chaulya et al 2000;Dutta & Agrawal 2003;Ghose & Majee 2007;Maiti 2007;Sinha et al 2009;Ahirwal et al 2018;Bandyopadhyay et al 2018;Jambhulkar & Kumar 2019;Raj 2019), China (Kim et al 2018;Tang et al 2018), Brazil (Dick et al 2006), Colombia (Domínguez-Haydar et al 2018, Russia (Naprasnikova 2008;Bragina et al 2014;…”
