“…In addition, soil was more saturated at FCC (28–38% moisture) than at TRC (19–24% moisture) prior to study initiation. Studies have shown that herbicide mobility is positively correlated with rate of runoff (Calderon, De Luna, Gomez, & Hermosin, 2016; Duhan, Oliver, Rashti, Du, & Kookana, 2020; Gouy et al., 1999; Meite et al., 2018; Potter, Bosch, & Strickland, 2015; Smith, Franti, & Comfort, 2002). The rate of runoff increases as soil saturation increases (Armbrust & Peeler, 2002; Meite et al., 2018; Müller, Stenger, & Rahman, 2006; Smith et al., 2002) and as the rate of irrigation or rainfall increases (Müller, Trolove, James, & Rahman, 2004).…”

Flazasulfuron is a selective herbicide registered for use in warm-season turfgrass. Concerns have been raised over its mobility in surface water runoff. Studies were conducted in Blacksburg, VA and Charlottesville, VA to evaluate injury to Lolium perenne L. (perennial ryegrass) downslope of plots treated with transition-assisting herbicides, including flazasulfuron, pronamide, and trifloxysulfuron sodium. Flazasulfuron (52 g a.i. ha -1 ) and pronamide (1120 g a.i. ha -1 ) consistently injured L. perenne greater than trifloxysulfuron sodium (17 g a.i. ha -1 ) or lower rates of flazasulfuron (9 and 26 g a.i. ha -1 ). At Charlottesville, soil was more saturated, and a natural rainfall increased the rate of runoff and severity of L. perenne injury below treated plots. At this site, flazasulfuron (52 g a.i. ha -1 ) and pronamide (1120 g a.i. ha -1 ) caused visible injury to L. perenne 10 to 16 m below treated plots. Based on L. perenne injury, flazasulfuron mobility at the rates tested can be considered equivalent or greater than trifloxysulfuron sodium, and equivalent or less than pronamide when subjected to excessive irrigation or rainfall soon after application to saturated soils. Precautions should be taken to avoid application of these herbicides to saturated soils and apply when rainfall is not expected for sufficient time to rinse turfgrass foliage and incorporate nonabsorbed herbicide into soil via light irrigation.

“…Values of trifluralin's K fa in soil varied from 20.1 to 743 L Kg −1 [48,50], and from 290 and 1590 for zeolites and 3240 for activated carbon [62]. In [63], k d values between 106 and 294 were obtained for the adsorption of trifluralin in five agricultural soils of the UK and K oc values of 63 ± 10. k d values of 1.28, 1.6, 57.6, 332 to 807, and 87 to 1010 L Kg −1 were obtained for atrazine sorption on ultisol [64], soil amended with sewage sludge [32], soil amended with organic waste from sugar mills [65], biochars from peanut shell [29] and slow pyrolysis biochars from vegetal materials [36], respectively. The adsorption of endosulfan sulfate in clay or composted soils was studied in [66], with obtained K fa values between 200 and 520 L Kg −1 and 80 for sandy soil.…”

The use of pesticides presents a risk to terrestrial and aquatic ecosystems. For this reason, the development of strategies to prevent and restore pollution is of the greatest interest, including the adsorption to organic matter. The aim of the present study was to investigate the sorption/desorption and kinetics of atrazine, chlorfenvinphos, endosulfan sulfate, and trifluralin onto several raw organic wastes by batch experiments. Three kinetic models were used to fit the obtained sorption kinetics data and two to fit the obtained adsorption isotherm data; both the Freundlich and pseudo-second-order kinetic models described the sorption isotherms well. The desorption study revealed hysteresis in all cases, showing strong, and not completely reversible, adsorption in most cases, with the exception of atrazine-sawdust and chlorfenvinphos-sawdust and chicken manure combinations, for which responses were weak and irreversible. The best kinetic, adsorption and desorption constants were achieved for the hydrophobic pesticides. With respect to sorption-desorption rates, orujillo was found to be the best adsorbent for atrazine, while composted urban solid waste was more suitable for trifluralin and endosulfan sulfate. Sorption constants and simple correlations indicated that, not only the organic matter content, but also the nature of the organic matter itself, and the pesticide and adsorbent properties, determine pesticide sorption-desorption. The use of wastes as efficient and cheap adsorbents for reducing the risk of pesticide pollution is proposed.

“…Fewer studies have addressed the adsorption-desorption of several pesticide-organic residue combinations or the amendment effect on soil physical properties. Duhan et al [109] have studied the behavior of five herbicides commonly used in sugarcane production (imazapic, atrazine, hexazinone, diuron, and metribuzin) by eleven waste materials (mill muds) and by three soils amended with them at different rates (5-25%, dry weight basis). The authors have observed that all the amendments enhance the adsorption efficiency for four of the five herbicides, depending on the rate of application, especially in the soil with low OC.…”

Effect of Organic Residues on Pesticide Behavior in Soils: A Review of Laboratory Research

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.
