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 cultivation. Glyphosate is used for controlling weeds and terminating cover crops, but its persistence in soil raises concerns about environmental impacts and soil health.

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

Microscopic pores are extremely important to oxygen movement and availability.

The microbes that possess the enzymes capable of cleaving this bond depend on high oxygen availability to do so efficiently. Understanding these factors is essential for minimizing the environmental impacts of glyphosate.
