Heavy metals, as the most common pollutants in sewage sludge, can be identified as the leading limiting factor determining the direction and nature of the biogeocenoses development. A significant part of heavy metals is included in soil-forming processes and absorbed by vegetation [1]. Leaching and migration of heavy metals in the soil are caused by differences of soils that cannot inactivate the leaching of heavy metals to different degrees, which makes it difficult to choose the soil that could be most suitable for normalization purposes [2]. With a radial distribution of heavy metals, the highest concentrations can be concentrated in the upper

“…It is necessary to determine enzymatic activity and to understand factors regulating it in order to characterize soil metabolic potential and fertility. This can be used to study biochemical processes occurring in soil and to evaluate soil quality [6][7][8][9]. Information regarding enzymatic activity, coupled with information on other soil properties, facilitate the selection of soil use [10,11].…”

“…This parameter reflects the level and extent of pollution found in the environment [8]. Soil enzymatic activity can be influenced through agronomic practices (fertilization) [9]. Farming system (organic or conventional) and catch crops (in particular under the organic system) also have a significant impact on the activity of soil enzymes [18,19].…”

This study was conducted over the period 2017–2019 in Czesławice (central Lublin region, Poland). The aim of the present study was to compare chemical soil quality parameters (soil pH, available P and K, organic carbon, and total nitrogen content) and soil enzymatic activity (dehydrogenase, acid phosphatase, alkaline phosphatase, urease, protease) in organic and conventional farming systems. The experimental design included two crop rotations (organic and conventional) in which identical plant species were grown: sugar beet-spring barley-red clover-winter wheat-oats. The loess soil on which the experiment was conducted was characterized by the grain size distribution of silt loam, and this soil was categorized as good wheat soil complex (soil class II). The experiment was set up as a split-plot design in triplicate in plots with an area of 40 m2. Soil sampling was carried out using a soil auger within an area of 0.20 m2 (from the 0 to 20 cm layer) in each plot during the autumn period. Over the 3-year study period, it was found that the organic system contributed to an increased soil content of organic carbon and total nitrogen. Moreover, a significantly higher soil pH value and a favorable narrow C/N ratio were found under the organic system (regardless of the crop species). Under the conventional system, in turn, a higher soil phosphorus and potassium content was observed. Enzymatic tests of the soil in the five-field crop rotation proved significantly higher activity of all the enzymes studied (in particular that of dehydrogenase, protease, and urease) in the organic system relative to the conventional one, regardless of the crop plant. Among the plants grown in crop rotation, sugar beet, and red clover had the most beneficial effect on the activity of the soil enzymes, followed by oats (especially under the organic system). The activity of the studied enzymes in the organic system was positively correlated (statistically significantly) with favorable soil pH, a higher content of organic C, and total N, and C/N ratio.

“…Thus, these findings lead us to the hypothesis that domestic SS (5 t ha -1 ) can be safely disposed of in agricultural soils. Many previous studies have shown that soil enzyme activity is revived by the incorporation of SS (Medina et al, 2015;Skowrońska et al, 2020;Curci et al, 2020), this is due to the substantial accumulation of nutrients, organic matter, and the increasing microbial population, applied with SS.…”
