“…In addition, both pesticides were also found at 30 cm of depth as was observed in other studied soil profiles (Landry et al, 2005;Veiga et al, 2001). Candela et al (2010) found glyphosate and AMPA concentrations at 1.9 m depth in coarse sandy soils from Barcelona, Spain with the risk of groundwater contamination.…”

“…Absorbed glyphosate and AMPA can be desorbed at the water-soil interface (Borggaard and Gimsing, 2008;Candela et al, 2007;Coupe et al, 2012;Donald, 2002;Passeport et al, 2014), and competition with phosphates for adsorption sites may lead to free glyphosate rather than the bound form in the soil matrix (Borggaard and Gimsing, 2008;Gimsing et al, 2004;Zhou et al, 2010). The free forms of glyphosate and AMPA are thus easily dispersed, especially in wet soils due to preferential flow (Vereecken, 2005), and heavy rains shortly after glyphosate application increase the entry of glyphosate to surface water bodies through transport with runoff and suspended load (Botta et al, 2009;Candela et al, 2010;Gjettermann et al, 2009;Peruzzo et al, 2008;Stone and Wilson, 2006;Vereecken, 2005). Luijendijk et al (2003) reported that up to 24% of the glyphosate sprayed on hard surface soil was transported in runoff to surrounding fields, and Todorovic et al (2014) showed that approximately 47% of applied glyphosate was transported in the runoff associated with erosion and tillage managements (plough or not).…”

“…While several recent studies highlighted the potential risk of ground and/or surface water pollution by leaching of glyphosate (Borggaard and Gimsing 2008;Candela et al 2010), risks of glyphosate toxicity to non-target plants in soils are generally considered as marginal, since glyphosate in the soil solution is prone to rapid microbial degradation (Giesy et al 2000) or almost instantaneous inactivation by sorption to the soil matrix (Piccolo et al 1992;Giesy et al 2000).…”

Phytotoxicity of glyphosate soil residues re-mobilised by phosphate fertilisation

et al. 2011

It has been repeatedly demonstrated that phosphate (P) and the herbicide glyphosate compete for adsorption sites in soils. Surprisingly, the potential consequences of these interactions for plants e.g. resolubilisation of phytotoxic glyphosate residues in soils by application of P fertilisers or by root-induced mechanisms for P mobilization have not been investigated so far. In model experiments under greenhouse conditions, the potential for glyphosate re-mobilisation by P-fertiliser application was evaluated by bio-indication with soybean (Glycine max L.) cultivated on five contrasting soils with or without glyphosate application at 10-35 days before sowing. Different levels of P-fertilisation (0, 20, 40, 80, 240 mg P kg −1 soil) were supplied at the date of sowing. Visual symptoms of glyphosate toxicity, plant biomass, intracellular shikimate accumulation as physiological indicator for glyphosate toxicity and the plant nutritional status were determined. On glyphosatetreated soils, P application induced significant plant damage. Expression of damage symptoms declined in the order Arenosol > Acrisol ≈ Ferralsol > Luvisol subsoil > Regosol. On the Arenosol, Ferralsol and Luvisol subsoil plant damage was associated with increased shikimate accumulation in the root tissue. On the Acrisol decline of germination and plant damage in absence of shikimate accumulation indicate toxicity of AMPA (aminomethylphosphonic acid) as the main metabolite of glyphosate in soils. On the Regosol, a growth-stimulating effect of glyphosate soil application (hormesis) was detected. The results suggest that remobilisation of glyphosate may represent an additional transfer pathway for glyphosate to non-target plants which is strongly influenced by soil characteristics such as P fixation potential, content of plant-available iron, pH, cation exchange capacity, sand content and soil organic matter.
