The increase in chemical pesticides in the soil causes great damage to the environment, humans, and animals, leading to the destruction of many beneficial and harmful organisms in the soil. This study aimed to identify the effect of Pseudomonas and Trichoderma with organic matter on the productivity of potatoes and the residue after using the glyphosate pesticide. The soil was analyzed before and after planting, estimating elements that affect soil fertility, including total nitrogen, organic carbon, phosphorus, pH, salinity, carbonates, bicarbonates, calcium carbonate, calcium, sodium, and other essential elements for plants.The treatments regarding organic matter showed that treatment C5 excelled over the rest of the treatments, with a value of 200.600 ppm, followed by treatment C1 with a value of 200.101 ppm, and treatment C7 with a value of 200.001 ppm. Treatments C3 and C8 had equal values of 199.812 ppm. Regarding the interaction between the concentration of the pesticide and temperature, the relationship was significant at a 0.05 level, indicating that high temperature is an important factor in the decomposition of the pesticide. The results of the study indicated that higher pesticide concentrations require longer periods for decomposition, assisted by bacteria and fungi present in the soil, specifically using Trichoderma fungus and Pseudomonas bacteria to decompose glyphosate.
