Soil Mixtures

Compositions of artificial soil mixtures, including sand, clay, defecation mud, waste from wet magnetic separation and plant residues in different proportions have been developed. The components were preliminarily comminuted by an auger-drill in order to obtain a homogeneous composition with subsequent granulation, stored in natural conditions in the autumn-winter period, followed by filling in experimental vessels. No any phytotoxic effect for the initial components and for all analyzed samples of the obtained artificial soil mixtures was detected. The chemical composition and some physicochemical properties of artificial soil mixtures, such as density, deposit of moisture and humus content, were determined. It was shown that the samples of the obtained soil mixtures are close to the control (dark gray forest soil of the Belgorod region) and can be recommended for further use in creating cultural landscapes as a substitute for natural soil. The developed type of artificial soil mixtures is suitable for the cultivation of bulbous crops; moreover, a large increase in yield in comparison with the control for some compositions was found. Artificially created soil mixtures reduce the harmful effect on the environment by eliminating the storage of industrial waste such as iron ore and food, plant residues used in the composition of the artificial soil mixture. Artificial soil mixture can be used for remediation of technologically disrupted areas, which will allow restoring disturbed lands and reducing man-caused impact on solid waste landfills. The addition of industrial waste allows them to be re-involved in the technological cycle, which contributes to the development of low-waste and waste-free technologies. The results obtained indicate the possibility of using the studied soil mixtures for cultivation of the decorative bulbous plants. To recommend the developed compositions for the use in agriculture, it is necessary to assess the possibility of impurity translocation from soil samples into cultivated crops.

Abstract. In order to investigate the optimal thickness of infiltration media in the Constructed Rapid Infiltration System, the artificial soil column is used to simulate the Constructed Rapid Infiltration System, and the CODCr, NH3-N and TN concentrations of the effluent from all the sampling sites are monitored. The experimental results and analysis show that the thickness of infiltration media exerts a significant influence on the CODCr, NH3-N and TN concentration and removal efficiency of the effluent; the CODCr, NH3-N and TN are mainly removed in the 0-1800mm zone of the artificial soil column; the total CODCr removal efficiency increases, as the thickness of infiltration media increases, but the CODCr removal efficiency in the 1800-2200mm zone is very low; the NH3-N and TN removal efficiency reaches the maximum where the thickness of infiltration media is 1800mm; the NH3-N and TN concentration of the effluent from 1800-2200mm zone dose not decrease, but increase 5-8%, due to the assimilation denitrification and amemoniation reaction on the end of the anaerobic zone; in consideration of the effluent quality, efficient biodegradation zone, construction investment, etc. the optimal thickness of infiltration media in CRI system should be 1800mm.

The Impact

Low impact development (LID) practices, such as bioretention and sand filter basins, are stormwater control measures designed to mitigate the adverse impacts of urbanization on stormwater. LID treatment performance is highly dependent on the media characteristics. The literature suggests that bioretention media often leach nutrients in the stormwater effluent. The objective of this study was to analyze the treatment performance of different sand and bioretention soil mixtures. Specifically, this investigation aimed to answer whether the use of limestone and recycled glass could improve the treatment performance of bioretention systems. Column experiments were designed to assess (1) the removal efficiencies of different sand and bioretention soil mixtures and (2) the impact of plant uptake on removal rates. Enhanced pollutant removal was observed for the custom blends with addition of limestone sand, indicating mean dissolved and total phosphorus removal of 44.5% and 32.6% respectively, while the conventional bioretention soil mixtures leached phosphorus. Moreover, improved treatment of dissolved and total copper was achieved with mean removal rates of 70.7% and 93.4%, respectively. The results suggest that the nutrient effluent concentration decreased with the addition of plants, with mean phosphorus removal of 72.4%, and mean nitrogen removal of 22% for the limestone blend.
