The adsorption, desorption, degradation, and mineralization of C-glyphosate [-(phosphonomethyl)glycine] were examined in Catlin (a fine-silty, mixed, superactive, mesic Oxyaquic Argiudoll), Flanagan (a fine, smectitic, mesic Aquic Argiudoll), and Drummer (a fine-silty, mixed, superactive, mesic Typic Endoaquoll) soils under oxic and anoxic soil conditions. With the exception of the Drummer soil, soil aeration did not significantly alter the adsorption pattern of C-glyphosate to soils. Herbicide… 
Monoammonium Phosphate Effects on Glyphosate in Soils: Mobilization, Phytotoxicity, and Alteration of the Microbial Community
Abstract Application of monoammonium phosphate has been demonstrated to re-immobilize glyphosate sorbed by soil under model laboratory experiment conditions. This effect was most pronounced in the
Changes in soil pH and addition of inorganic phosphate affect glyphosate adsorption in agricultural soil
Glyphosate is the most widely used herbicide in Argentina. The strong sorption of glyphosate to the mineral fraction of the soil can be affected by environmental conditions and agricultural

TLDR
It is concluded that when mixtures of phosphate, herbicides and antibiotics are present in soil, the greatest influence of their competitive interactions is phosphate decreasing glyphosate sorption and the presence of phosphate in solution lessens the potential impact of MCPA on glyphosate Sorption.
Influence of electrolyte composition and pH on glyphosate sorption by cow-dung amended soil
TLDR
CD application as soil amendment for agriculture could impede glyphosate sorption and facilitate its off-site leaching and contamination of surface and groundwater, this study noted.
Phosphate fertilizer impacts on glyphosate sorption by soil.
Interactions among Glyphosate and Phosphate in Soils: Laboratory Retention and Transport Studies.
TLDR
The results indicate that the timing of inorganic P fertilizers relative to GPS applications has a significant impact on the fate of the herbicide in soils and suggest that GPS may be more liable to leaching in scenarios in which P fertilizer are applied after the application of GPS-based herbicidal formulations.
Adsorption-desorption and leaching potential of glyphosate and aminomethylphosphonic acid in acidic Malaysian soil amended with cow dung and rice husk ash
TLDR
G glyphosate is a transitional herbicide; therefore, its leaching potential in the soil is low, despite the addition of cow dung or rice husk ash, which could be beneficial in increasing adsorption and enhancing degradation of these compounds.

Sorption and leaching of 14C-glyphosate in agricultural soils
Glyphosate (N-(phosphonomethyl)glycine) is one of the most widely used herbicides in the world to control weeds in agricultural and urban areas. Its increasing use requires special attention to its
Effects of phosphate on the adsorption of glyphosate on three different types of Chinese soils.
TLDR
The results indicated that Freundlich equations used to simulate glyphosate adsorption isotherms gave high correlation coefficients (0.990-0.998), meaning a complex interaction occurred among glyphosate, phosphate and the soils.
Extraction of glyphosate herbicide from soil and clay minerals and determination of residues in soils
Extraction of the herbicide glyphosate [N-(phosphonomethyl)glycine] from clay minerals and two soils was studied by a batch equilibrium technique. Experiments showed that, for most of the

TLDR
The data strongly suggest that RU was the direct cause of the enhanced microbial activity in soils tested, and appeared to be rapidly degraded by soil microbes regardless of soil type or organic matter content, even at high application rates.

TLDR
The aim of this review is to present and discuss the state of knowledge on sorption, degradation and leachability of glyphosate in soils, which suggests that glyphosate leaching seems mainly determined by soil structure and rainfall.
