The present study was conducted at a coal mining affected forest and a non-affected forest to analyze the seasonal changes in soil physico-chemical properties, incorporate additive and weighted soil quality index (SQI) to determine the soil quality and check the affected forest soil pollution status. Comparative SQI shows that the non-affected forest presented higher SQI in all the seasons (winter, spring, summer and autumn). However, in both the forest the seasonal additive and weighted SQI was categorised as autumn > summer > spring > winter and the overall SQI of the soil depth was ranked as 0–10 > 10–20 > 20–30 cm. The Single pollution index (PI) points out that cadmium (Cd) was the main potential contributor to soil pollution while the Pollution load index (PLI) and Nemerow integrated pollution index (NIPI) revealed moderate soil pollution status. The result summarized that coal mining activities can elevate soil deterioration rate, such as loss in soil organic carbon, reduction in nutrient availability, and slowing down the rejuvenating process of forest soil.

Soil Quality Assessment

Soil has multiple functions, including the provision of habitat to organisms, and most biological activities occur in the surface soil. Due to the negative effects of soil erosion, efforts for soil conservation are being made, including the development of a reliable index that can help assess soil quality. In this study, the physical and chemical properties and biological genes from grassland topsoil were analyzed, in order to identify surface soil organism markers that could be used as a soil quality index. Six spots of grassland topsoil were analyzed, one high-quality and five low-quality, based on a web-based soil quality assessment module. Consequently, eukaryotes and prokaryotes with different soil quality ratios were compared and examined. The following bacteria and archaea have the potential to be used in soil quality assessment: circulation of materials including nitrogen, Nitrospira spp., Candidatus Nitrososphaera, and Candidatus Nitrosotalea; biological purification, Geobacter spp.; pathogens, Burkholderia spp., Paraburkholderia spp., Pseudomonas brassicacearum, and Rhizobacter spp.; antibiotic secretion, Candidatus Udaeobacter; and material degradation Steroidobacter spp. and Rhodanobacter spp. This study provides primary data for identifying biological markers for soil quality evaluation. In the future, a wider variety of data need to be accumulated to develop a highly reliable index related to soil quality.

Abstract The aim of this study was to assess the possibility of using biological and biochemical parameters in the evaluation of forest soil quality and changes caused by land use. The study attempted to determine a relationship between the enzymatic activity of soil, the number of earthworms and soil physico-chemical properties. The study was carried out in central Poland in adjoining Forest Districts (Przedbórz and Smardzewice). In soil samples taken from 12 research plots, basic physico-chemical properties, enzyme activity (dehydrogenase, urease) and density and biomass of earthworms were examined. Enzyme activity showed a large diversity within the forest site types studied. The correlations between the activity of the enzymes studied and C/N ratio indicated considerable importance of these enzymes in metabolism of essential elements of organic matter of forest soils. Urease and dehydrogenase activity and earthworm number showed susceptibility to soil pH, which confirmed relationships between enzyme activity and abundance of earthworms and soil pH in H2O and KCl.

Diagnosis of the risk of soil pollution and the performance of measures for the recovery of contaminated soil requires proper monitoring of the extent of soil function damage and its recovery process. Soil enzymes reveal ecosystem perturbations, are sensitive to management choices, and have been used as indicators of biogeochemical cycles, organic matter degradation, and soil remediation processes. Thus, enzymes can indicate, along with other physical or chemical properties, soil quality. In this paper, we review the effects of soil pollutants [toxic trace elements (TTE), and petroleum hydrocarbons (PHC)] on enzymatic activities and evaluate the usefulness of soil enzyme’s activity for monitoring recovery processes in contaminated soil. Soil enzymes can be said to be a powerful means of monitoring to properly indicate the degree of deterioration of soil quality caused by soil pollution and to diagnose the process of functional recovery of contaminated soil. Further research is needed to establish the quantitative relationships between the soil physico-chemical properties and enzyme activity and the effect of soil remediation on the functional recovery of soil-related to soil quality.

ABSTRACT Using domestic sewage to irrigate and supply nutrients to plants is a sustainable practice; however, due to the physical and chemical properties of the domestic sewage, soil attributes and quality may be changed with its application. The aim of this study was to evaluate soil quality after two cycles of sugarcane irrigated with treated domestic sewage and surface reservoir water via subsurface drip irrigation, with and without nutritional supplementation by fertigation, and a non-irrigated control with top-dressing fertilization. Soil quality was established by applying the methodology proposed by Karlen & Stott. Physical, chemical and microbiological indicators were selected to compose the basic soil functions used to determine the quality index. Application of treated domestic sewage with fertigation increased soil electrical conductivity, Na+ content and exchangeable sodium percentage. Reservoir water applications with fertigation increased microbial biomass carbon and reduced the metabolic quotient, besides promoting significant effects on soil acidification indicators in comparison to reservoir water irrigation without fertigation. Despite the alteration of some soil attributes, no significant changes in the soil quality index were observed among the treatments.

Two vegetation-growing concrete slopes completed are chosen as research objects and the Analytical Hierarchy Process method is adopted to establish the evaluation index system, aiming at quantifying the physical and chemical properties of the base material and analyzing the results contrastively. The study shows that the physical and chemical properties of vegetation-growing concrete base material keep improving with the growth of time to better adapt to the growth of vegetation. This evaluation results tally with the actual situation of the sample sites, which suggests that this base material soil quality index system has great practical value. The differences occurring in the evaluation value of two pieces of sample sites suggest that regional environment is the main factor to affect the quality of vegetation-growing concrete base material.

AbstractA successive 2-year (2019 and 2020) field experiment was conducted in northern Bangladesh (Rangpur district) to observe the status of soil quality and heavy metal risk due to tobacco cultivation in this area. Soil samples were collected randomly from four major sub-districts (Rangpur Sadar, Badargonj, Gangachara, and Mithapukur Upazila) where Mithapukur was a non-cultivating tobacco field and the rests were tobacco-growing fields. Along with heavy metal concentrations, physicochemical parameters were analyzed to observe the progressive change in the soil. Results depicted that values of bulk density, particle density, porosity, soil organic matter (SOM), and major nutrients (N, P, K, S) were decreased in the tobacco-growing field from 2019 to 2020, whereas significant improvement was observed in non-tobacco-growing field at successive year analysis. However, exchangeable bases were raised in the tobacco cultivated field from 40.86 to 52.98% compared to the non-tobacco cultivated field which was in a declining trend (43.66–34.33%). Overall, the soil pollution index depicted that Pb was shown a moderate risk of contamination in 2020. The ecological risk analysis also stated that the tobacco field in Rangpur Sadar was at a moderate risk of soil pollution (RI = 126.16), although the non-tobacco field in Mithapukur was at no risk of pollution (RI = 45.23). So, it can be recommended that tobacco cultivation harms the soil health, and thus, it should be prohibited from the agricultural field.

Land continuously planted with corn will decrease land quality. Good land quality is needed to support soil function as a growing medium and keep a sustainable environment. This research was aimed to identify the soil quality index at land unit planted with corn in Mungka, ,Lima Puluh Kota Regency. This research used an explorative descriptive method through land survey and soil analyses in the laboratory. The samples were taken based on purposive random sampling at each land unit under the same slope (8%). There were three land units being sampled, and those were corn-corn, corn-eggplant, and corn-cassava cropping pattern. Corn-corn ropping pattern had the best soil quality index (0.89), followed by corn-cassava (0.86), and corn-eggplant (0.85) on the top 20 cm soil depth. On the 20-40 cm soil depth, the soil quality indices 0.82, 0.82, 0.83, for corn-eggplant, corn-corn, and corn-cassava cropping pattern, respectively. The quality index of the land under the corn cropping pattern was considered good either on the top 0-20 cm or 20-40 cm soil depth. This was due to the addition of organic matter from poultry manure to the land regularly. Based on this research, it is recommended to apply OM regularly to corn cropping pattern to keep a good soil quality index.

Abstract. Assessment of soil quality is one of the key parameters for evaluation of environmental contamination in the mining ecosystem. To investigate the effect of coal mining on soil quality, opencast and underground mining sites were selected in the Raniganj Coafield area, India. The physical, chemical, biological parameters, heavy metals, and PAHs contents of the soils were evaluated. Soil dehydrogenase (+79%) and fluorescein (+32%) activities were significantly higher in underground mine (UGM) soil, whereas peroxidase activity (+57%) was higher in opencast mine (OCM) soil. Content of As, Be, Co, Cr, Cu, Mn, Ni, and Pb was significantly higher in OCM soil, whereas, Cd was higher in UGM. In general, the PAHs contents were higher in UGM soils probably due to the natural coal burning in these sites. The observed values for the above properties were converted into a unit less score (0–1.00) and the scores were integrated into environmental soil quality index (ESQI). In the unscreened index (ESQI-1) all the soil parameters were included and the results showed that the quality of the soil was better for UGM (0.539) than the OCM (0.511) soils. Principal component analysis was employed to derive ESQI-2 and accordingly, total PAHs, loss on ignition, bulk density, Be, Co, Cr, Ni, Pb, and microbial quotient (respiration: microbial biomass ratio) were found to be the most critical properties. The ESQI-2 was also higher for soils near UGM (+10.1%). The proposed ESQI may be employed to monitor soil quality changes due to anthropogenic interventions.
