Summary, etc. This study examines organophosphate pesticide residues in rice soils and farmers' practices in three barangays of Concepcion, Tarlac_Talimundoc San Miguel, Pitabunan, and Sto. Niño over three months. It assesses soil properties, pesticide practices, residue levels, their correlations, and sustainable recommendations. Soil samples, tested via Gas Chromatography-Mass Spectrometry, showed undetectable residues (<0.01 mg/kg) pre- and post-harvest, despite widespread Brodan and Malathion use, likely due to leaching in sandy loam soils (Talimundoc San Miguel, Sto. Niño) and loam (Pitabunan), and degradation at near-neutral pH (6.38–6.64). All 195 male farmers used chemical pesticides; 38.9%-67.7% applied with the wind, increasing drift, and 31.5%-63.2% used full protective gear, linking to health issues like eye irritation (52%-71.7%) and headaches (38.35%-60.4%). Improper disposal (19.7%-42.6% left in fields) risked non-target species (e.g., dragonflies, frogs). Low IPM (25%-32.9%) and INM (24.1% -27.6%) adoption showed chemical reliance, despite 69.23%-75% hazard awareness. Undetectable residues suggest rapid dissipation but not risk elimination. Recommendations include promoting IPM, protective gear, better disposal, soil testing, and organic fertilizers. These findings offer baseline data for sustainable rice farming in Concepcion, Tarlac, enhancing soil health, farmer safety, and biodiversity.
