Monitoring and Assessment of the Microbial Populations and Chemical Characteristics of Paraquat Treated Soil

The aim of this analysis was to look at the microbial community and chemical components of soils that had been treated with paraquat. The soil samples were handled with paraquat at three different concentrations: low (0.3 ml/L), prescribed (0.6 ml/L), and high (0.9 ml/L). Normal techniques were used to perform microbial and chemical experiments. Microbes like Staphylococcus sp., Micrococcus sp., Pseudomonas sp., Escherichia coli, Bacillus sp., Actinomycetes bovis, Actinomycetes israeli, Streptomycetes sp., Aspergillus fumigatus, Aspergillus niger, Aspergillus flavus, Absidia  The microbes were affected by the paraquat application to the soils at different weeks after application (WAA), as most were found absent in some of the treated soil samples, as shown by the results of the control soil samples. The organic matter and carbon contents of the paraquat-treated soils were significantly higher (P=.05) at the 4th WAA, with 1.93 percent, 1.93 percent, and 1.84 percent and 1.34 percent, 1.12 percent, and 1.12 percent, respectively, while the pH of the soils was significantly higher (P=.05) at the 2nd WAA, compared to the other WAA and control soils. Similar doses of paraquat at different WAA have different effects on soil microbial communities and chemical components. As a result, the effects of paraquat on the microbial community and chemical components of soil varied depending on the quantities used and the time it was applied. Since the fungi, bacteria, and actinomycetes species included in this study were herbicide-sensitive, they could be used as a reliable indicator of soil biological importance. It also decides the form of microbes in the soil by killing those that are unable to tolerate its effects, leaving only the resistant ones.
