Although glyphosate is a commonly used herbicide, its impacts on ecosystems are not well understood.
A pot experiment, was established to explore the potential impacts of biochar, wood vinegar, and plants
on the environmental fate of glyphosate. In the presence of plants (Lolium perenne), and irrespective of
the presence of biochar or wood vinegar, leaching of glyphosate through the soil was multiple compared
to the plant free systems. However, the addition of biochar to the soil decreased the leaching of
glyphosate irrespective of plants. Soils treated with biocharewood vinegar mixture showed the lowest
glyphosate leaching, both with and without plants. Biochar, wood vinegar or plants, alone, had no effect
on the degradation of glyphosate in soil. When the plants were present the degradation of glyphosate
was highest in soils treated with biocharewood vinegar mixture. Our results imply that biochar in
particular can be applied as a soil improving agent to reduce the potential environmental risks to aquatic
environments caused by glyphosate
