“…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).…”
