“…In older studies, urease activity and pH were not significantly correlated [71]. Soil urease activity was significantly negatively correlated to catalase activity (Figure 7), which is contrary to the findings of the previous study [2]. is may be due to the anaerobes that were predominant in the Sandwich compost substrate amended soil.…”

“…Soil urease activity and pH were significantly positively correlated (Figure 8). Soil pH that is close to neutral demonstrated significantly high urease activity [2,72]. Increasing soil pH by liming significantly increased soil urease activity and the growth of urease-producing microbes [73].…”

“…Soil enzyme activity is closely correlated to the amount of soil organic matter, plant, soil, root, and microbial biomass [1]. Besides, soil enzyme activity is a ected by abiotic factors such as pH, temperature, moisture content, and soil cultural management, which is largely a ected by anthropogenic pollutants (such as zinc) and commercial fertilizer [2].…”

Soil enzymes ensure our food security, yet they are vulnerable to abiotic stresses. Solving the global issues of food waste by amending the Sandwich compost can be a great solution to ensure food security. Food waste Sandwich compost substrate (as soil amendment) and leachate (as seed priming solution and liquid fertilizer) were used to grow Bok Choy for 4 growing cycles, where soil pH, cation exchangeable capacity, moisture content, aggregate stability, and enzyme activity were determined. The Sandwich compost substrate amendment increased soil pH close to neutral and CEC up to 1.5-fold. Anaerobic Sandwich compost substrate-amended soil reduced soil catalase activity. Still, it steadily increased during the growing cycle. The Sandwich compost substrate amendment soil sustained the aggregate stability for 4 growing cycles. On the flip side, aggregate stability without the Sandwich compost substrate amended soil declined from the growing cycle to the next growing cycle. All variables were positively correlated except catalase activity. Henceforward, Sandwich compost substrate is recommended to improve soil quality in the aspects of pH, CEC urease activity, and dehydrogenase activity.

“…In the first part of the work it was shown that the catalase activity was most associated with the influence of the railway. It is known that the catalase activity is an integral indicator of the state of the soil, which responds both to natural factors (Olkova & Tovstik, 2022) and anthropogenic pollution (Hinojosa et al, 2004;Utobo & Tewari, 2015). In the case of the influence of railways on the soil it can be argued that the catalase activity was inhibited by a complex of pollutants, since a strong dependence of the catalase activity on the distance from the site to the railway was revealed (r = 0.95).…”

Urbanozems with typical pollution are formed along railways: heavy metals (HM), oil products, anthropogenic organic matter. Depending on the natural zone and intensity of the leaching regime, the accumulated pollution can have a different effect on the integral environmental indicators of soils – the toxicity and enzymatic activity. The aim of the work was to determine the influence of the railway on the physicochemical characteristics of adjacent urbanozems that are formed in the southern taiga zone and to find out the interrelation of these indicators with the toxicity and catalase activity of the soil. Samples of urbanozems were taken from the surface layer of 0-10 cm at the distance of 50 m west and east of the railway and at the distance of 100, 500, 1000 m of it (east). The pH, content of organic matter, humus, ammonium nitrogen, mobile forms of HM, mortality for Daphnia magna Straus, influence on bioluminescence of Escherichia coli Migula, and the catalase activity were determined in the samples. It was shown that the levels of toxicity and the activity of catalase are strongly related to the distance from the railway: Pearson’s coefficients (r) were -0.53 (D. magna), -0.69 (E. coli), 0.95 (catalase). However, the interrelation between the total pollution index (TPI) of metals and integral indicators is lower: r=0.50 for the pair “D. magna – TPI”, r=0.42 for “E. coli – TPI”, r=0.19 for “catalase – TPI”. Consequently, the reactions of living organisms and the activity of catalase were formed in response to a combination of pollutants, not to one group of compounds.
