Geoclimatic modeling and assessment of pesticide dynamics in Indian soil.

ABSTRACT: Although pesticides can protect crops from pests and diseases, their extensive use poses significant environmental risks through soil quality degradation and groundwater contamination. Pesticide dynamics in soil are influenced by geoclimatic factors. The aim of this study was to evaluate local variability in pesticide dynamics based on geoclimatic variation across India at the individual farm level and to identify emerging patterns of pesticide residue accumulation in the soil. Using a bioreactive transport simulator, biogeochemical models from 19,573 farms were evaluated to study the dynamics of 46 pesticides across India by incorporating farm-level data on soil and climatic conditions. Hotspots of pesticide leaching and residue accumulation were identified by analyzing several parameters
