“…Therefore, an important element in management of soils is to prevent their degradation. Taking preventive actions is considered to be a better approach than the subsequent implementation of soil remediation measures [5][6][7][8][9]. Soil is an irreplaceable element of the environment and it is subjected to the pressure of various degrading factors.…”

The ten-year experiment on the soil physical properties of biochar-amended Podzol was studied. Biochar was applied to the soil in the following rates: treatment BC10—10 Mg × ha−1, treatment BC20—20 Mg × ha−1, treatment BC30—30 Mg × ha−1 and treatment BC0—Control (soil without the addition of biochar). Biochar was mixed the soil arable layer (0–20 cm). Soil samples were collected ten times, once a year—after harvest rye. They were taken from layers: 0–10 cm and 10–20 cm, in six replicates, using 100 cm3 metal cylinders. The soil physical properties were determined: particle size distribution, particle density, bulk density, total porosity, air capacity and permeability (at −15.5 kPa), water content at sampling, field water capacity (at −15.5 kPa), available and unavailable water content, and the ratio of field water capacity and total porosity was calculated. It was found that biochar application causes changes in the soil physical condition. The soil density decreased, while the porosity, aeration and water retention increased; the ratio of field water capacity and total porosity was favorable. These changes cannot be considered as permanent. Most of the analyzed properties showed a durability of no more than 3–4 years. We found that biochar incorporation into soil is a good method for environmental management of waste biomass.

“…On the other hand, Szymanek et al [82] reported a negative impact of EM on the amount of available forms of soil phosphorus, potassium, and magnesium. Likewise, long-term studies by Pranagal et al [71] did not confirm the positive effect of EM on the physical properties of the soil, and the application of the preparation led to a decrease in the content of organic carbon in the soil. In our research, a moderate effect of the EM preparation on the content of OC, TN, P, Mg, and TMN in the soil was observed, although, usually, the values of these parameters were higher in the variants including their application.…”

“…Even though the number of scientific publications on the impact of EM on the physical and chemical properties of soil is relatively high, there are just a few studies on the effect of their use on soil microorganisms. Pranagal et al [71] suggest the prudent use of this type of product due to the risk of disturbance in the functioning of the soil environment as a result of the introduction of foreign microorganisms and their ability to decompose soil organic matter. Other authors [26], however, negate the possible permanent effects of EM on the composition and activity of indigenous soil microorganisms, assuming the short-term nature of possible changes in their numbers.…”

In order to meet the global nutritional needs of a growing population, attempts are being made to develop strategies that can effectively offset the negative effects of intensive farming. The aim of this study was to investigate the effect of Effective Microorganisms (EM) preparation and organic matter incorporation on the soil microbiological and chemical features. The analyses included the number of heterotrophic bacteria, fungi, actinobacteria, cellulolytic, amylolytic and proteolytic microorganisms, and bacteria of the genus Azotobacter. The content of organic carbon, the total and mineral nitrogen forms of phosphorus, potassium, magnesium, and the pH were also determined. The application of an EM of higher dose combined with the manure and straw resulted in the highest abundance of heterotrophic bacteria (165.1 × 106 cfu g−1), actinobacteria (43.2 × 105 cfu g−1), cellulolytic (17.2 × 106 cfu g−1), and proteolytic bacteria (82.0 × 106 cfu g−1). The highest content of chemical parameters was always observed in the experimental variant, including biomass incorporation, accompanied by EM use. The novelty of our research is the analysis of the synergistic effect of the experimental factors studied on the microbiological and chemical parameters of arable soils.

“…The measurements carried out in the third decade of June showed a decrease in aeration porosity in all variants compared to the measurements carried out in May. Researchers investigating effective microorganisms found no significant effect on porosity (Pranagal et al, 2020). At the end of July, aeration porosity ranged from 33.76% to 43.29%.…”

Abstract. The introduction of innovative technologies in agriculture is key not only to improving the efficiency of agricultural production, crop yields, and quality but also to balancing energy use and preserving a cleaner environment. Biopreparations are environmentally friendly means of restoring the vitality of the soil on which plants can thrive. Biopreparations have an impact on soil health and alter greenhouse gas emissions. The aim of this work was to investigate the effects of different biopreparation formulations on soil physical properties and CO2 emissions from the soil by establishing correlations. The experimental studies were carried out over three years, and each spring, after the resumption of winter crops, the soil surface was sprayed with biopreparations of different properties or mixtures of biopreparations, under 7 scenarios, with one scenario left as a control. Soil porosity, temperature, and CO2 emissions from the soil were measured regularly every month from April to August. The application of the biopreparations showed a cumulative effect on the soil properties. In the third year of the study, the total porosity of the soil was higher in all scenarios compared to the control, ranging between 51 % and 74 %. The aeration porosity of the soil was also higher in all years of the study than in the control, although no significant differences were obtained. The results of the studies on CO2 emissions from the soil showed that in the first year, the application of the biopreparations increases emissions compared to the control. However, when assessing the cumulative effect of the biopreparations on soil respiration intensity, it was found that in the third year, most of the biopreparations led to a reduction in CO2 emissions compared to the control. The lowest emissions were achieved with the biopreparations consisting of essential oils of plants, 40 species of various herbs extracts, marine algae extracts, Azospirillum sp., Frateuria aurentia, Bacillus megaterium, mineral oils, Azotobacter vinelandi, humic acid, gibberellic acid, sodium molybdate, azototbacter chroococcum, azospirillum brasilense, etc.
