Soil is an ecosystem capable of producing the resources necessary for the development of the living organisms. Soil microorganisms (bacteria and fungi) are responsible for biomass decomposition, biogenic element circulation, which makes nutrients available to plants, biodegradation of impurities, and maintenance of soil structure. The presence of microorganisms in soil depends on their chemical composition, moisture, pH, and structure. Human activity has an indispensable influence on the formation of ecosystems. Soil tillage has an impact on the chemical and physical parameters of the soil, and thus on its biological properties. The use of inappropriate agro-technology can lead to degradation of the soil environment. Changes in soil properties may cause changes in soil abundance, activity, and diversity. Cultivation can affect microorganisms, causing their mortality and reducing the availability of nourishment in the soil. Therefore, it is extremely important to assess the diversity and microbiological activity of soil in relation to soil-tillage technology.

The increase in flooding in Europe is linked to the presence of excessive moisture in many areas. Enzymes are a sensitive parameter of soil environment, therefore we have made an attempt to assess the impact of simulated flood conditions on their activity. We determined the activity of dehydrogenases and acid and alkaline phosphatase after 7 and 14 days of flooding the three Fluvisols with river water in controlled conditions. The obtained results indicate a significant influence of soil moisture on enzymatic activity and soil pH, which indicates that the soil environment is changing as a result of flooding.

“…The research results of Furtak and Gajda (2017) showed that ecological (without mineral fertilization and plant chemical protection) farming system beneficially influenced soil environment and soil were characterized by a higher DH activity. The research conducted by Siddikee et al (2011) indicate that the soil chemical variables related with salinity-sodicity are relevant related with the sampling distance from the causes and are the stress factors, which greatly affect microbial and biochemical properties.…”

1Abstract. To study the effects of anthropogenic salinity-sodicity on dehydrogenase (DHA) and catalase (CAT) activity in soil, samples were collected from the Ciech Soda Polska S.A. Plant in Inowrocław. The soils closest to the plant were assayed to determine pH, electrical conductivity (EC 1:5 ), and enzymes activity. The soil resistance (RS) and resilience (RL) indices were computed. The soil was sampled in July and October 2015 from the plant area not covered by the recultivation treatments (locations no 1, 2, 3, 4) and the locations where the agrotechnical soil recultivation was performed (5, 6). The successive soil sampling locations (7,8) were located in the vicinity of the plant, while the control (point 9) -beyond the impact of the plant. Soil was sampled from the depth of 0-20 cm and 20-40 cm. To compare the activity of the oxydoreductases sampled from various locations, indices were calculated to facilitate estimation of both soil processes degradation and recultivation. It has been observed that the highest value of pH KCl and electrical conductivity increased the CAT and inhibited the DH activity. RS values for the dehydrogenase activity closed to 0 for the soil from stands in the vicinity of the plant, meaning the effect of saline on soil not only in places of stored post-soda sludge, but also in the area near the Ciech Soda Polska S.A. The highest value of soil catalase RL in location no 5, 0-20 cm deep, from recultivation area suggests a correct recultivation.
