الملخص
تعتبر المبيدات من اهم ملوثات التربة، اذ لا يمكن التخلص منها بسهولة كون العديد منها له نصف عمر أكثر من سنة الى عشرة سنوات، في هذه المقالة سنتعرف على المبيدات واهميتها، وكذلك كيف تتم عملية التحلل الحيوي لها، ومدى تأثير معدل نمو الميكروبات عند تعريضها للظروف البيئية المثلى.
كشفت الابحاث السابقة عن مدى كفاءة الميكروبات في عملية التحلل الحيوي للمبيدات حيث ان درجة الحرارة المثلى لعملية التحلل الحيوي هي 40 م˚، وان الرطوبة تأثر سلبا على فعالية المبيدات حيث تؤدي الرطوبة العالية الى التقليل من فعالية المبيد كما ان درجة الحموضة المثلى لزيادة فعالية البكتريا هي، اما بالنسبة لفترة الحضانة فوجد خلال الدراسات السبقة ان أفضل فترة حضانة هي 5-7 ايام حيث يزداد خلالها تطبع البكتريا للمبيدات وزيادة التحلل الحيوي لها.
