In other words, low doses of glyphosate equal to the amount plants are exposed to in spray drift, can result in iron deficiencies in the plants. For crops destined as animal feed or as human food, this could result in decreased dietary iron.
== Impact on Microorganisms ==
"Subsequent research on glyphosate interactions with soil microorganisms demonstrated that although glyphosate was metabolized by a segment of the microbial population, it was also toxic to several bacteria and fungi; the net effect glyphosate appeared to be a disruption of soil and root microbial community composition because selected components of the microbial community were stimulated while others were suppressed."<ref>Preface "Glyphosate interactions with physiology, nutrition, and diseases of plants: Threat to agricultural sustainability?", European Journal of Agronomy 31 (2009) 111-113.</ref>
