The management of large volumes of organic residues generated in different livestock, urban, agricultural and industrial activities is a topic of environmental and social interest. The high organic matter content of these residues means that their application as soil organic amendments in agriculture is considered one of the more sustainable options, as it could solve the problem of the accumulation of uncontrolled wastes while improving soil quality and avoiding its irreversible degradation. However, the behavior of pesticides applied to increase crop yields could be modified in the presence of these amendments in the soil. This review article addresses how the adsorption–desorption, dissipation and leaching of pesticides in soils is affected by different organic residues usually applied as organic amendments. Based on the results reported from laboratory studies, the influence on these processes has been evaluated of multiple factors related to organic residues (e.g., origin, nature, composition, rates, and incubation time of the amended soils), pesticides (e.g., with different use, structure, characteristics, and application method), and soils with different physicochemical properties. Future perspectives on this topic are also included for highlighting the need to extend these laboratory studies to field and modelling scale to better assess and predict pesticide fate in amended soil scenarios.

有机残留物对土壤中农药行为的影响:实验室研究综述

对各种牲畜,城市,农业和工业活动中产生的大量有机残留物的管理是环境和社会利益的主题。这些残留物中有机物含量高,意味着它们作为农业土壤有机改良剂的应用被认为是更可持续的选择之一,因为它可以解决不受控制的废物积累的问题,同时改善土壤质量并避免其不可逆转的降解。但是,在土壤中存在这些改良剂的情况下,可以改变用于增加农作物产量的杀虫剂的行为。这篇综述文章探讨了农药在土壤中的吸附,解吸,消散和浸出如何受到通常用作有机改良剂的不同有机残留物的影响。根据实验室研究报告的结果,已评估了与有机残留物(例如,改良土壤的来源,性质,组成,比率和孵化时间),农药(例如,具有不同残留量)相关的多个因素对这些过程的影响。用途,结构,特征和使用方法),以及具有不同理化特性的土壤。还包括有关该主题的未来观点,以强调需要将这些实验室研究扩展到田野和模型规模,以更好地评估和预测在改良的土壤情景中的农药命运。特性和使用方法),以及具有不同理化特性的土壤。还包括有关该主题的未来观点,以强调需要将这些实验室研究扩展到田野和模型规模,以更好地评估和预测在改良的土壤情景中的农药命运。特性和使用方法),以及具有不同理化特性的土壤。还包括有关该主题的未来观点,以强调需要将这些实验室研究扩展到田野和模型规模,以更好地评估和预测在改良的土壤情景中的农药命运。
