“…This should be connected to the fact that biochemical activities/processes carried out by microorganisms are accompanied by decarboxylation, and hence CO 2 release, therefore the decrease in their activity was reflected in a lower amount of CO 2 . Relationships between the amount of CO 2 produced and enzymatic and biochemical activity in soil were also found by other authors [15,38]. In the present study, PCA distribution showed a strong relationship between ammonification and CO 2 emission, suggesting that ammonifiers contributed to the production of this gas under the conditions of this experiment.…”

Research was conducted in connection with the pressure exerted by man on the environment through the use of pesticides. The aim of the study was to assess the impact of pesticides on soil and to evaluate the effect of these changes on greenhouse gas emissions into the atmosphere. The research was carried out on soil sown with oilseed rape. The activity of protease and urease, ammonification, nitrification in soil, as well as CO2 (carbon dioxide) and N2O (nitrous oxide) gas emissions from soil were assessed. The analyses were carried out directly after harvest and 2 months after. Pesticides most frequently negatively affected the tested parameters, in particular enzymatic activities. Of the two herbicides used, Roundup had a stronger negative impact on microbial activity. The application of pesticides, especially the fungicide, resulted in an increase in gas emissions to the atmosphere over time. Pesticides disturbed soil environmental balance, probably interfering with qualitative and quantitative relationships of soil microorganism populations and their metabolic processes. This led to the accumulation of microbial activity products in the form of, among others, gases which contribute to the greenhouse effect by escaping from the soil into the atmosphere.

“…Enzymatic activity is a good indicator of the biochemical changes taking place in the studied media. The results of the studies on the activity of selected enzymes were often used as a basis for the assessment of soil quality [Joniec andFrąc, 2017, Ning et al, 2017], topsoil layer of reclaimed and unreclaimed post-mining sites [Heděnec et al, 2017;Błońska et al 2019] or composted waste with different origin used as organic fertilizers [Cordovil et al, 2017]. The activities of three basic enzymes that play an important role in the transformation of compounds contained in the soil: dehydrogenase (EC 1.1.1) -which is an indicator of the intensity of the degradation of carbon compounds, urease (EC 3.5.1.5) -being an indicator of the transformation of nitrogen compounds, and phosphatase (EC 3.1.3), indicating the intensity of phosphorus compounds transformation (Enzyme Nomenclature 1992), were adopted to assess the quality of the tested fertilizers.…”

A mixture of digestates from biogas plant and bottom ashes from biomass combustion can be a valuable source of nutrients and organic substances as well as an improver of the adsorption capacity and water-air properties of the soil. Pelletization of such a mixture makes its composition more stable and the handling easier. However, the properties of pelletized fertilizer are affected by the external factors. The paper presents the results of the research on the impact of air accessibility during the storage of fertilizer pellets produced on the basis of digestate from biogas plants, bottom ashes derived from the biomass combustion and mineral additives (quicklime, zeolite and bentonite) on their fertilizing properties, enzymatic activity and technical parameters, such as resistance to mechanical loads. The research showed that the fertilizers stored under the roof, exposed to the atmospheric air for 1 year, contained by 5.5% more water compared to the samples shielded from the air. These more humid fertilizers were also characterized by slightly higher nitrogen content and 1.7-fold lower enzymatic activity of dehydrogenases and 1.6-fold higher activity of phosphatases, but their resistance to mechanical loads, both static and dynamic was lower. On the other hand, the effects of storage conditions on the urease activity and the content of potassium, phosphorus and heavy metals were not observed. Generally, the storage of fertilizers in airtight containers is more advantageous, because under such conditions the changes in the fertilizing properties are insignificant, while their resistance to mechanical loads is much higher.

“…Soil, as the top layer of the earth's crust and, therefore, a very important element of many ecosystems, is constantly being degraded. The causes of this degradation include various factors, which can be considered from three aspects, being chemical [1,2], biological [3,4] and physical [5,6]. Considering physical soil degradation, water erosion can be distinguished in particular [7,8].…”

Influence of slope incline on the ejection of two-phase soil splashed material

Soil splash is the first step in the process of water erosion, where impacting raindrops cause the detachment and transport of soil material. One of the factors that strongly influences the magnitude of soil splash is the incline of the surface (slope). The aim of this study was to investigate the effect of the slope on the course of the splash phenomenon caused by single-drop impact (one drop impact per soil sample), with respect to the mass and proportions of the ejected material, taking into account its division into solid and liquid phases i.e. soil and water. The investigation was carried out using three types of soil with different textures, in moistened (pressure head corresponding to -1.0 kPa) and air-dry (-1500 kPa) conditions. The soil samples were on three angles of slope, being 5°, 15°, and 30°, respectively. After a single-drop impact with a diameter of 4.2 mm, the ejected material was collected using a splash cup. The following quantities of splashed material were measured: the total mass, the mass of the solid phase, and the mass of the liquid phase. Additionally, the distribution and proportions (soil/water) of the splashed material were analysed in both the upslope and downslope directions. It was found that: (i) the change of slope had a variable influence on the measured quantities for different soils; (ii) in the case of moistened samples, the measured values were mainly influenced by the texture, while in the dry samples, by the angle of the slope; (iii) with the increase of slope, the splashed material was mostly ejected in the downslope direction (irrespective of moisture conditions); (iv) in the moistened samples, the ejected material consisted mostly of water, while in the dry samples it was soil—this occurred for material ejected both upslope and downslope. The obtained results are important for improving the physical description of the process of splash erosion. A more thorough understanding and better recognition of the mechanisms governing this phenomenon at all stages could contribute to the development of more effective methods for protecting soil against erosion.
