Impact of Oxygen and Cultivation on Glyphosate Breakdown

The breakdown of glyphosate in soils is influenced by three key factors: oxygen availability, soil biology, and the presence of cultivations. Glyphosate is effective for controlling weeds and terminating cover crops, but its persistence in soil raises concerns about environmental impacts and soil health.

According to Rothamsted Research microbiologist Prof Andrew Neal, oxygen availability within the soil is essential for effective glyphosate degradation. Glyphosate contains a strong carbon-phosphorus bond, which requires substantial energy to break.

Microscopic pores are extremely important to oxygen movement and availability.
