“…The authors of these studies indicate both inhibitory and stimulating effects of these preparations on the development of fungi and actinomyces (Crouzet et al 2010;Sebiomo et al 2011). Upadhyay and Dutt (2017) reported that there are species among fungi and actinomyces that use pesticides as a source of carbon, nitrogen, phosphorus or sulfur. Mineralizing these xenobiotics, they contribute to their detoxification.…”

The aim of the work was to evaluate the impact of use of conventional and organic cultivation systems on selected parameters of microbial activity in the soil under wheat, barley and oat cultivation. Microbiological, biochemical, enzymatic and metabolic activities were analyzed during three seasons over 3 years in soil. The more beneficial effect of organic cultivation was reflected in the increase in bacterial growth, the intensification of the nitrification and higher activity of all analyzed enzymes. The conventional system was more favorable for the development of fungi. The assessment of the metabolic profile of soil microorganisms demonstrated clear differences between the activity of microorganisms in the organic and conventional systems. The results indicate that cultivation of soil in the organic system is more conducive to the environment. The authors conducted research, because there is no unambiguous answer to the question which growing system is more beneficial for soil biological life, i.e., the basis for food production. Microorganisms that are the object of these studies form the basis for the fertility of all soil ecosystems. Graphic abstract

“…chemical plant protection agents (pesticides). As shown by Upadhyay and Dutt [ 57 ], fungi, bacteria, and actinomycetes exhibit varied ability to transform and degrade pesticides. Among these microorganisms, the greatest ability to degrade xenobiotics is attributed to fungi due to their high resistance to adverse environmental conditions.…”

“…This process requires appropriate conditions, including C abundance and adequate soil pH [ 28 ]. Bacteria and soil fungi use pesticides as a source of energy by metabolizing them in enzymatic processes [ 57 ]. Therefore, the addition of pesticides may cause an increase in enzymatic activity of the soil.…”

“…Literature review shows that herbicides applied in agriculture differently affect soil environment, including microorganism activity which are responsible for soil fertility and health status [ 35 , 36 , 43 , 48 , 57 ]. There is a need to conduct a comprehensive assessment of the condition of soils treated with chemical plant protection products.…”

Purpose The use of glyphosate in agriculture raises a lot of controversy because research concerning its impact on the soil provides contradictory information. However, despite these negative opinions, glyphosate is still used in agricultural practice. Therefore, for a more complete assessment, the authors carried out research using traditional microbiological methods and a modern method of metabolic profile analysis in glyphosate-treated soil. Methods The study was carried out on the soil witch was sown with six cultivars of rapeseed. Seven days before harvest, the plants were sprayed with the herbicide. The analyses consisted in determining the number of selected groups of microorganisms, biochemical and enzymatic activity, and differentiation of the catabolic potential of soil microbial communities. Results The results showed significant changes in the analyzed parameters. Respiratory activity and ammonification processes were stimulated in the treatments with rapeseed cultivation treated with the herbicide. Changes in the enzymatic activity were generally positive. The EcoPlate assessment of microbial community catabolism showed that the highest activity was recorded in the soil sown with the cultivars Belinda, Tamarin, and Sw svinto. Concurrently, these soils were characterized by the highest correlations between rapeseed cultivar and metabolic activity. Conclusion Cultivation of specific plant varieties that reduce the negative effect of herbicides used in agriculture may be one of the methods to prevent soil degradation. In our research, Belinda turned out to be a cultivar, under the cultivation of which an increase in the activity of microorganisms was recorded most frequently compared to soil not sown with rapeseed.

“…According to other authors, stimulation of ammonification in soil with pesticides could result from the mineralization of organic compounds present in pesticides or dead biomass of microorganisms that proved sensitive to these chemicals [35]. In addition to the negative effect caused by their binding to the active center of enzymes, thereby reducing their catalytic activity, pesticides can also be an additional source of nutrients for microorganisms, e.g., C and N [3,30,36]. As a result, the activity of bacteria and fungi may increase [37].…”

Microbiological Nitrogen Transformations in Soil Treated with Pesticides and Their Impact on Soil Greenhouse Gas Emissions

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.
