The effect of thinning of young spruce stands by 500 trees/ha on biological activity in the soil profile was studied in the mountainous area of the Moravian-Silesian Beskids. The biological activity of soil was determined under optimal laboratory conditions by tests of soil respiration, catalase activity and intensity of cellulose decomposition. No statistically significant differences were found between the individual biological tests when the two experimental stands were compared (P-level 0.05). All biological activities within each stand were correlated, and significant correlations were fo

The causes of forest vegetation degradation can be logging, fires and windthrow. Initial soil alteration may be different: soil mixing and scalping during logging and skidding, pyrogenic impact, windthrow with plant roots, etc., as well as other factors. Further evolution of post-forest soils in the absence or weak erosion follows a similar scenario. The driving force is increased insolation of soil surface at elimination of closed tree crowns, which leads t

Soil microbial functional diversity under maize grown in different agricultural management practices was determined using the Biolog EcoPlates and other microbial and biochemical methods. Comparisons of substrate utilization and the diversity indices showed differences in community composition of microorganisms related to different cultivation techniques and seasons. The soil samples collected in spring were characterized by statistically significant lower indices of biological activity in comparison to the soil collected from the flowering stage of maize.

The use of living organisms as biological indicators for environmental change necessitates the development of a number of criteria on the basis of which it is possible to select indicator species. These include the biological activity of soils (mesofauna, enzymes). Bioindicators with a chronic anthropogenic load on the soil, in particular with prolonged application of fertilizers, can react to very weak effects due to dose accumulation, in addition, they make it unnecessary to use expensive and laborious physical and chemical methods for measuring biological parameters.

Abstract The clay mineral bentonite has received a lot of attention for its potential to reduce the harmful effects of drought on soil health and biological activity. Reduced enzymatic activity and microbial diversity are two negative outcomes of the drought’s impact on soil quality. Bentonite, however, has been shown to aid in the restoration of biological functions in drought-affected soils. Bentonite’s function as a soil moisture retainer is an important consideration. Bentonite acts as a reservoir, trapping water within its layers due to its high water-holding capacity and ability to form

Abstract The biological and biochemical parameters of two types of permafrost soils of the Yeravninsky basin (the carbon content of the microbial mass, different groups of microorganisms, protease, catalase and the intensity of cellulose decomposition) were studied, depending on the water-thermal properties and the type of soil formation. It is established that permafrost soils do not have an optimal combination of potential and real (actual) enzymatic activity. It is also noted that the acidic reaction of the soil solution and the low availability of nutrients in sod-taiga soils increases the
