Ecological Assessment of Rapeseed Cultivation to Improve Chemically Degraded Urban Albic Luvisol
Urban ecosystems, compared to natural, are often characterised with the presence of plots with high content of different heavy metals. In this regard, the complex continuous monitoring of the dynamics of on-going changes in urban ecosystems against the background of natural processes is of enormous importance. The principal indicators of the urban soil environmental sustainability include its respiration ones and balance of microbial carbon that could be sensitive to the increased content of heavy metals too.
Experiments were conducted to determine the phytoremediation potential of spring rapeseed plants cultivated on the Albic Luvisol artificially contaminated with zinc and nickel in the dose range of 400–800 and 30–60 mg kg−1 of soil respectively. The aim of the study was a comprehensive environmental assessment of biological productivity and zinc and nickel uptake by the spring rapeseed plants with determination of eco-physiological indicators of its microbial community state and metal accumulation indices. The experimental data showed, that the rapeseed plants were able to overcome heavy metal-induced toxicity and accumulate zinc and nickel in the aboveground part of the plants with enrichment factor (EF) 0,9–4,8 and 2,0–3,4 respectively. The microbial activity of Albic Luvisol at the beginning of vegetation had strong positive correlation with the rapeseed plants cultivation on the presence of toxic elements in the soil.
