Assessment of Bacterial Resistance and Soil Quality Parameters in Glyphosate-Treated Agricultural Irrigation Areas

This study evaluates bacterial resistance and soil quality parameters in agricultural irrigation areas using glyphosate, focusing on the Icó-Mandantes and Apolônio Sales projects in Petrolândia, Pernambuco. The research investigated the physicochemical characteristics of the soil, such as density, particle size composition, pH, and nutrient levels (P, Ca, Mg, Na, K, Al). Soil samples were collected and analyzed to identify the presence of antibiotic-resistant bacteria. The results show that, although the physicochemical parameters are within acceptable standards, there is a significant presence of resistant bacteria, especially Stenotrophomonas maltophilia, Bacillus cereus, and Enterobacter cloacae. The predominance of multi-resistant bacteria suggests that the continuous use of glyphosate may promote bacterial resistance, posing a risk to public health and agricultural sustainability. Therefore, the study highlights the need for more sustainable agricultural practices and continuous monitoring of glyphosate's effects on soil.
