The movement of pesticides in the soil has a significant effect, causing the failure of pest control, and environmental contamination. The results of this study were to investigate the environmental behaviour of glyphosate in the soil column. The data’s kinetic reaction was confirmed that glyphosate is subjected to Pseudo-first order rather than Pseudo-second order with the rate constant 0.042 h-1. This indicated that decreasing glyphosate concentrations can occur and gradually decline with time. The data also pointed out that glyphosate was more fitted to Freundlich compared to the Langmuir model. It scored 3.083 to 1.814, indicating the behaviour of glyphosate occurred in the various surfaces. The contribution coefficient of glyphosate between the soil and its solution Kd valued 0.33 mL. g-1, explaining that the herbicide is less mobile and tends to adsorb on soil particles. Overall data demonstrated that the kinetics of glyphosate under this current condition tends to be immobile.
