“…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.

“…Piled SMRs can be used as the primary substance for extracting biofertilizers due to their abundant nutritive compounds that were derived from fungus (Elsakhawy and El-Rahem, 2020). Another suggested way to reuse SMRs is the outlet as a substrate to amend soils (Li et al, 2020;Marin-Benito et al, 2020). The SMR compost was also suggested to be used as a growing-media that may partly replace peat for horticultural plant production (Caballero et al, 2009;Ribas et al, 2009).…”

In order to evaluate the effect of growing media with peat and spent mushroom residue (SMR) on medicinal plants, we cultured Gossypium herbaceum and Talinum paniculatum seedlings in the substrates with SMR in proportions of 0% (control), 25%, 50%, 75%, and 100%. Results showed that G. herbaceum seedlings can survive in all treatments, but T. paniculatum seedlings died out in 75% and 100% SMR substrates where higher electrical conductance was found (2.3-2.7 dS m-1). Both growth and biomass mostly declined with the increase of SMR proportion in the growing media for the two species except for root biomass in T. paniculatum seedlings between the control and the 25% SMR treatment. Shoot nitrogen (N) and phosphorus (P) concentrations and contents tended to be higher in low- and high-SMR-proportional substrates, respectively. N and P statuses were both diagnosed to be excessive than needed for the two species. Overall, it was not recommended to culture G. herbaceum seedlings in the substrates with SMR; instead T. paniculatum seedlings can be cultured in the growing media with SMR in volumetric proportion of 25%.

“…The soil dissipation of pesticides depends on several processes, with the most significant ones being degradation, adsorption, and mobility, which control pesticide behavior [11]. The dissipation rate of pesticides after the repeated application of the same pesticide, or another with a similar chemical structure, during several crop cycles may be accelerated by faster pesticide biodegradation due to microorganism adaptation, which affects their persistence and reduces their efficacy against weeds [12][13][14][15].…”

“…There are only a few results on the dissipation and persistence of chlorotoluron and flufenacet in unamended and amended soils at field scale [11,[25][26][27][28], being influenced by soil properties, herbicide characteristics, and environmental conditions. However, the dissipation of chlorotoluron after repeated application in field studies has been assessed solely in unamended soils [29].…”

“…This study therefore pursued the following objectives: (i) study the field dissipation kinetics of the herbicides chlorotoluron and flufenacet after their repeated application at the pre-emergence stage of winter wheat in an agricultural soil unamended and amended with two organic residues, (ii) compare their persistence with that observed the previous year after a first application in the same field experiment, and (iii) assess the influence of soil property evolution and weather conditions on the long-term dissipation and persistence of these herbicides. This study is part of a research project carried out under field conditions involving the dissipation and mobility of chlorotoluron and flufenacet over a 2 year experimental period following an initial, single application of the organic residues to the soil [11,30].…”

Organic wastes applied as composted amendments may improve the quality of degraded soils and modify the fate of pesticides. This work has set out to study the dissipation kinetics of the herbicides chlorotoluron and flufenacet during their second-year application in field experimental plots with a sandy-loam agricultural soil without amendment (S) and amended with spent mushroom substrate (S + SMS) or green compost (S + GC). The SMS and GC were applied to the soil during the previous winter’s wheat crop campaign (1 year before the second herbicide application) at rates of 140 and 85 t ha−1 (dry weight basis), respectively. The experiment involved randomized complete blocks with plots of 81 m2, including three replicates per soil treatment. Surface soils were sampled after herbicide application for 225 days, and herbicide residues in the soil samples were determined by HPLC-MS. The dissipation curves of both herbicides for the three soil treatments were better fitted to the first order multi-compartment (FOMC) kinetic model. The dissipation rates of the most hydrophobic herbicide, flufenacet, were slower than those for chlorotoluron in both unamended and amended soils. The half-life (DT50) values ranged between 20.7 to 41.1 days for chlorotoluron, and 42.9 to 75.6 days for flufenacet, and they followed the order S > S + SMS > S + GC. The DT50 values of chlorotoluron were close for S + SMS and S + GC, and the DT50 of flufenacet for S was similar to that for S + SMS. These DT50 values decreased up to four times with respect to those calculated after the first application indicating an accelerated dissipation of the herbicides after the second application especially in amended soil in comparison with unamended soil. The persistence of chlorotoluron and flufenacet in an agricultural soil was modified by the effect of the organic amendments, weather conditions, and possibly the repeated application of the compounds under real field conditions.
