Abstract

Pesticides and fertilizers are widely used in modern agriculture to increase crop yield. However, the long-term use of these agricultural chemicals may lead to the accumulation of residues in soil and groundwater, which will have a noticeable impact on the environment. The purpose of this study is to explore the influence of pesticide and fertilizer residues on soil and groundwater environment through long-term monitoring and impact study. Through the long-term monitoring of several experimental sites, it was found that firstly, pesticide residues had obvious negative effects on soil quality, leading to the decrease of soil microbial community and the damage of soil ecological function. Secondly, excessive use of pesticides and fertilizers leads to groundwater pollution, including excessive concentrations of organochlorine compounds, organophosphorus compounds and nitrates. This poses a serious threat to groundwater resources and related ecosystems. Therefore, in order to protect the health of soil, groundwater and ecosystem, it is urgent to adopt sustainable agricultural practices to alleviate these negative effects and ensure the ecological security of future generations.
