The Role of Pesticide Molecular Structures in Accelerating Soil Erosion: An Agricultural Perspective

Agricultural intensification has grown rapidly in response to rising population and food demand, particularly in developing countries where farming remains the backbone of rural livelihoods.Despite the modernization of machinery and communication technologies, the use of pesticides in many farming regions continues to rely on outdated practices.As a result, large quantities of chemically diverse pesticides accumulate in soils, influencing soil structure, biological activity, fertility, and long-term stability.This review examines how the molecular structures of commonly used pesticides, including organophosphates, organochlorines, carbamates, pyrethroids, neonicotinoids, and triazines, interact with different soil types, thereby accelerating soil degradation and erosion.The paper highlights how weak farmer awareness, limited access to organic alternatives, and insufficient policy support worsen the problem.In addition, the review identifies soil-crop-pesticide interactions and explains mechanistically how specific functional groups, halogens, aromatic rings, and persistent structures in pesticides alter soil chemistry and physical properties.The paper concludes with recommendations for sustainable pesticide use, improved farmer training, and a shift toward organic and soil-friendly practices.
