“…Finally, the third step prior to the use of organic residues as soil amendments from a beneficial agronomic point of view that avoids compromising the sustainability of soil and water resources would be to simulate the behavior of pesticides in amended soil scenarios. There is an important gap in this research field, as evidenced by the scarce studies reported in the literature, especially using the pesticide fate models usually applied in a regulatory context [171][172][173].…”

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.

“…There are many such models. For example, PEARL, a model for Pesticide Emission Assessment at Regional and Local scales, describes the fate of a pesticide in the soil‐plant system (Tiktac et al., 2012); PELMO, the Pesticide Leaching Model, simulates the vertical movement of pesticides in soil and can be used to predict pesticide leaching (Klein et al., 1997); PRZM, the Pesticide Root Zone Model, is often used to predict runoff from agricultural fields (Marin‐Benito et al., 2020); and MACRO, which is a preferential flow model used to assess pesticide leaching and drainage (Marin‐Benito et al., 2020; Nolan et al., 2008). There are also other models used to consider wider concerns.…”

Application of the Danish pesticide load indicator to arable agriculture in the United Kingdom

et al. 2021

Pesticides are an important component of worldwide agriculture systems and have contributed to significant increases in crop quality and yields and therefore to food security. However, despite their societal benefits, pesticides can be hazardous to humans and the environment. Therefore, effective pesticide polices are needed that balance the societal and economic benefits with the unintentional and undesirable environmental and health impacts. As a result, there has been consistent policy interest in pragmatic and practical techniques that are suitable for assessing the environmental and human health implications of agricultural pesticide use from a national perspective for assisting in the development of policy initiatives and for communicating policy outcomes to the public. The work described herein explored the appropriateness of the Danish Pesticide Load Indictor for assessing agricultural pesticides applied in the United Kingdom from 2016 and 2018. The findings for the two datasets appear broadly comparable, suggesting that the overall environmental load from pesticides on the U.K. environment remained relatively constant during this period. Regional differences in environmental load and the major contributing substances were identified. Where large differences between the two years were seen, regulatory interventions appear to have been the cause. Overall, the indicator behaves as expected and appears to be sufficiently responsive to changes in pesticide use. However, various concerns were identified that may lead to modifications in how the indicator is calculated and what parameters are included to make it better able to deliver U.K. policy objectives.

“…Organic amendment addition can change the physical (soil bulk density, aggregate stability, moisture retention and porosity), chemical (cationic exchange capacity, electric conductivity and addition of contaminants) and biological (stimulation of indigenous microflora and introduction of exogenous microorganisms) properties of soils. These changes can impact the fate of pesticides: in general, the mobility of pesticides decreases and their persistence increases in amended soils compared to unamended ones [4][5][6][7][8][9][10][11][12][13][14].…”

Effect of Multiple Stresses, Organic Amendment and Compaction, on the Fate and Impact of Isoproturon in Soil

Organic matter decline and compaction are two major processes of soil degradation. Organic amendment is a current practice to compensate the loss of organic matter, which could in addition contribute to increase soil aggregate stability and limit compaction. Therefore, the objective of this work was to study the effect of multiple physico-chemical stresses, organic amendment (compost of sewage sludge and green waste) addition and soil compaction, on the fate and impact (measured through the urease enzyme activity) of isoproturon. Compost addition and compaction did not significantly affect the fate and impact of isoproturon. The lack of effect of compost can be due to the delay between soil sampling and soil amendment. Compaction had no effect probably because the porosity reduction does not affect the habitable pore space accessible to degrading microorganisms. Nevertheless, isoproturon significantly increased the urease enzyme activity in compacted and not compacted unamended soils contrary to the amended ones. It seems that the organic amendment could act as a buffer with regards to the impact of isoproturon. The results obtained in this work suggest that, in general, the fate and impact of isoproturon in soils will not change following compaction and/or organic amendment addition, neither the corresponding risks for the environment.
