“…These effects are strongly correlated with the concentration of applied herbicide, its persistence, its physicochemical and behavioral characteristics and with the soil physicochemical parameters, respectively [11][12][13][14]. Literature data reveal the stimulation or inhibition of the enzymes' activities in the presence of herbicides, depending on the type of the herbicide, its dose, the incubation temperature, application interval, inorganic and organic soil content, soil type, soil maintenance works, heavy metal content and other environmental factors [15][16][17][18][19][20]. Soil temperature and humidity are two factors that reduce the herbicides toxicity and their persistence in soil [19,21,22].…”

This study assesses the effects of the herbicide oxyfluorfen on the activities of enzymes and on the populations of soil microorganisms by considering experiments on soil samples maintained in both laboratory and in field conditions. Furthermore, the molecular docking approach was used to evaluate the interactions of oxyfluorfen with enzymes found in soil. There was a dose dependent inhibitory effect of oxyfluorfen against the activities of dehydrogenase, phosphatase, protease and urease. The enzymes activities obtained for the soil samples maintained under field conditions usually reflected a different trend than those obtained under laboratory conditions, emphasizing the influence of the soil physicochemical properties. For soil samples maintained in field conditions and for the normal dose of oxyfluorfen, dehydrogenase activity recovered after 14 days and a minimum of 21 days was necessary for the recovery of phosphatase, urease and protease activity, respectively. The most important parameters of soil influencing the activities of enzymes and the populations of microorganisms were the pH, N-NO3 and N-NH4 contents. A dose dependent behavior of populations of microorganisms found in soil treated with oxyfluorfen has been shown. There was a slight grows of the colonies of microorganisms when oxyfluorfen was applied, but this growth decreased with increasing the oxyfluorfen concentration.

“…ha − 1 (Cherni et al 2015). Nguyen et al (2018) showed that effects on soil enzymes were lower in light textured Tenosol soil than Vertosol and Chromosol soils under glyphosate or Roundup CT application. Also, it was reported that the soil microbial structure of irrigated soils under herbicide (triasulfuron and prosulfocarb) treatment exhibited a higher proportion of Actinobacteria and lower relative amount of fungi than non-irrigated soils (Delgado et al 2019).…”

Application of the novel bioorganic fertilizer (BIO) is effectively used to inhibit weeds in rice paddies. To identify changes in soil bacterial community and enzymes in response to BIO treatments, field experiments were carried out in five major rice-growing areas in China. The dominant phylogenetic groups recorded included Proteobacteria, Actinobacteria, Bacteroidetes, Firmicutes and Acidobacteria. Anaeromyxobacter, Bacteroides, Bifidobacterium, Escgerichia- Shigella, Geobacter and Haliangium were significantly different and aided in general function (R), amino acid transport, metabolism (E) and transcription (K) clusters between BIO-treatment and untreated control. The soil chemical properties and enzyme activities were less affected by BIO at these study sites. RDA analysis showed that soil bacterial community had a significant positive correlations among northern latitude, eastern longitude, exchangeable K, total K, total P, soil pH, and total N, except for organic matter, hydrolytic N and extractable P. Overall, our work showed that application of BIO does not alter the main community structure and functional diversity of soil bacterial in rice paddies and should be encouraged for use as a sustainable weed management strategy.

“…Therefore, the addition of pesticides may cause an increase in enzymatic activity of the soil. The effect of glyphosate on soil microorganisms and its bioavailability and biodegradability depends on microbiome composition as well as soil properties and the type of preparation applied [ 6 , 17 ].…”

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.
