“…Such a highly toxic element is ubiquitous cadmium (Cd) (Liu et al, 2016;Shi-Wei et al, 2016;Peng et al, 2017). This work is focused on toxic Cd, which belongs to the element with a high risk potential for soil, plants and human health (Meharg et al, 2013;Das et al, 2014;Shi-Wei et al, 2016;Borgulat et al, 2018) and is focused on remediation medium -garden compost, which is usable in agricultural practices and has the potential to reduce the availability of toxic elements to the environment. It needs to be used more in the present practice.…”

Soil is a sensitive ecological factor. Biodegradable materials from the environment can also be used to deal with serious ecological problems. Soil affecting by remediation medium - garden compost - was analysed for toxic cadmium (Cd) in terms of environmental protection. The objective of this research was to analyse soil and compost at foothill locality of the Tribeč Mountains (Southwestern Slovakia) in the years 2015−2017 to determine Cd contents in soil and compost, pH and to assess Cd bioavailability. The analyses were carried out using the Atomic Absorption Spectrometry with seven-step Selective Sequential Extraction methods. The results obtained were evaluated statistically using the SAS 9.4 software method by Spearman’s correlation coefficient. The results showed that Cd contents in soil had reached 2.96 mg kg−1 and soil with compost (the ratio 1:1) 2.71 mg kg−1 dry matter. Cd contents in the soil exceeded maximum allowed limit of 196%. And deceased by 25% after adding compost. The pH in soil with compost varied from 6.78 to 7.98. The pH prevented the mobility of Cd about 8.3% in average. Statistical dependence was high, which was demonstrated for relationship between Cd in soil, pH and compost. Available Cd forms in soil were 53.3% and soil with compost were 45% in average. The garden compost as a remediation medium reduced Cd bioavailability.
