“…At the end of the study, the TOC content was significantly higher in soil treated with SSFAC. The results obtained confirm the thesis known from the literature that, in soil reclamation, the introduction of external organic matter and its quality are important for organic matter accumulation processes [104]. With a dose of 180 Mg•ha −1 SSC, more TOC was introduced into the soil than with SSFAC.…”

Mining leads to serious degradation of the ecological values of the landscape. After mining is completed, degraded areas should be reclamated in order to mitigate the destructive effects of mining activities. Effective reclamation aims to initiate soil-forming processes. The paper evaluates the effects of land reclamation in post-mining areas 12 to 14 years after the reclamation process. The assessment was based on a determination of the activity of selected enzymes. Municipal sewage sludge compost (SSC) and compost with a composition of 70% municipal sewage sludge + 30% fly ash (SSFAC) were used as an external source of organic matter in the reclamation. The activity of dehydrogenases, phosphatases, and urease was determined. The fertilization of reclaimed soil with compost caused a significant increase in the activity of the assessed enzymes. Significantly higher dehydrogenase activity was found in the soil treated with SSC. The soil treated with SSFAC was characterized by higher activity of phosphatase and urease. The one-time application of composts from sewage sludge and sludge with fly ash, and the introduction of a mixture of grasses, allow for a permanent reclamation effect. An additional ecological advantage of this reclamation model is waste management, which is part of the circular economy strategy.

“…The increase in soil enzyme activity is parallel to the increase in soil organic matter. This situation reveals that enzymes are linked to the population dynamics of the soil biota (Myszura et al, 2021). It is reported that the increase in urease activity with the addition of organic matter to the soil is mainly attributed to the nitrogen content of the added material (Piotrowska-Długosz et al, 2022).…”

A large amount of plant pruning waste occurs after annual care in banana production areas. This waste material contains significant amounts of organic substances and nutrients. In this study, banana waste compost (BWC) was applied to the soil both alone and in mixture with leonardite (LT) and vinasse compost (VC). Treatments include: control (CL), banana waste compost alone (BWC-2: 2 t da-1; BWC-4: 4 t da-1; BWC-8: 8 t da-1), leonardite alone (LT: the recommended application rate), leonardite with banana waste compost (BWC-2+LT; BWC-4+LT; BWC-8+LT), vinasse compost alone (VC: the recommended application rate), vinasse compost with banana waste compost (BWC-2+VC; BWC-4+VC; BWC-8+VC). Afterwards, the changes in the activities of nitrogen (NH4+NO3) and phosphorus (available P) related enzymes (urease and alkaline phosphatase) were monitored through analyzes made on soil samples taken on certain days (0th, 10th, 20th, 40th, 80th). During this period, the pH and EC values of the soil were also measured. According to the results obtained; it was determined that banana waste compost combined with leonardite generally positively affects the pH, EC, exchangeable NH4-NO3 and, available P of the soil, as well as the activity of urease and alkaline phosphatase compared to other treatments. In this regard, according to the control, the urease activity of the soil increased by 875%, the alkaline phosphatase activity by 149%, the exchangeable NH4+NO3 by 188%, available P by 83%, and the EC value by 100%. However, the pH value decreased by about 5%. As a result, it can be stated that the application of banana waste compost combined with leonardite as a soil conditioner at least 4 t da-1 will be economical and 10 to 20 days after this application, nitrogen and phosphorus availability will increase in the soil.

“…In the soil, non-specific (carbohydrates, phenols, amino acids, fats, alcohols, etc.) and specific (humus substances) organic compounds can act as substrates [48,49]. Dehydrogenases act as catalysts for a wide range of oxidative reactions that are associated with the degradation of soil organic matter [50].…”

One of the most modern and effective methods of soil restoration after pollution is the use of bioremediation. In recent years, special attention has been paid to the use of biochar. However, the ecological state after the introduction of biochar into petroleum-hydrocarbons-contaminated soils at different levels of pollution has been little studied. The work objective was to study the effect of biochar (10% of the soil mass) on the ecological statement of Haplic Chernozem contaminated with different levels of oil, from 0.1 to 50% of the soil mass. To assess the state of Haplic Chernozem after remediation with biochar, indicators of the biological activity of soils were studied. The maximum information content in the case of oil pollution and remediation with biochar was established by the activity of dehydrogenases (r = −0.90) and the total number of bacteria (r = −0.98). When applying biochar, the maximum stimulations of the integral indicator of the biological state (IIBS) relative to the background, by 62, 76, and 72%, were noted in samples with oil at concentrations of 0.5, 25, and 50%, respectively. The results of the study should be used for biodiagnostics and monitoring of the state of oil-contaminated Haplic Chernozem at different levels of contamination after remediation with biochar.
