Abstract:

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 presented mini-review shows a systematic picture of the biological activity of soils in its connection with physical and chemical properties, and, ultimately, with soil fertility and crop yields. The biological activity of soils is due to the lifetime activity of soil biota, mainly microbiota and root systems of plants, as well as the action of soil enzymes. It has been shown that individual BAP tests can be used as simple and accessible biological fertility indices BFI.

An important biological property of the soil is its regenerative ability, which is the basis for agricultural reproduction of soil fertility. It depends not only on individual chemical or physical parameters, but also on the functioning of the soil biota, the cycle of processes in the “plant–soil” system. The change of vegetation cover leads to a change in the composition of soil biota, disruption of the circu-lation of substances and a decrease in bioproductivity.

This is a fairly stable organic compound that is destroyed only by very strong oxidants.

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.

Abstract:

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.

Higher heavy metal content in soils (Cd, Pb, Zn, Cu) is due to composition of the parent rock, emissions from lead processing industry and the leak of toxic material from the steel works sludge ponds in the 1970s and 1980s. The samples were collected from six sites located at different distances from the contamination source (the former sludge ponds) and chemical and biological properties were determin

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

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

In different experiments, a different nature of changes in the reaction of the soil environment and the content of organic carbon, an increase in the content of readily soluble salts, was established.
