One of the most significant obstacles to achieving sustainable agricultural practices and ensuring ecological sustainability is the build-up of herbicides in the soil. Paraquat is a non-selective, highly toxic, and very herbicides. The main objective of this research project was to evaluate two inexpensive & sustainable techniques to enhance the degradation of paraquat residues in the soil: soil solarization and composting. The experiment was conducted over two months (July and August). Paraquat was removed from the soil through the use of four different treatments: (i) a control group, (ii) an isolated treatment group that received only solarization, (iii) an isolated treatment group that received only compost, and (iv) a combined treatment group that used both solarization and composting. Samples were taken from each group after 14, 28, and 45 days, when a separate treatment is applied to solarization (or) compost; there has been a reduction in residue by approximately 45% (or) 50%, respectively, over 45 days. However, by combining both treatments, a success rate of more than 75% has been achieved, indicating the synergistic benefit of the two methods working together more effectively than either could do alone. The reasoning behind these findings lies in the combination of the two methods, utilizing synergistic mechanisms. First, during solarization, the plastic sheeting creates an area of increased temperature that accelerates the thermal degradation of organic matter in the soil, and second, compost provides a boost to microbial enzymatic degradation of organic matter (as opposed to solely relying on the solar effect). In conclusion, it is believed that by combining solarization with organic fertilization, there is both a practical and economic option for soil improvement (contaminated soils) and further supports the movement towards eco-friendly and sustainable practices of agricultural management.
