Relationship of C added from glyphosate and C mineralized 55 days after glyphosate addition in (a) Blount0, a soil with no reported application of glyphosate, (b) Blount1, a soil with a history of moderate glyphosate application, and (c) Bennington2, a soil with a history of heavy glyphosate application. Carbon mineralization from basal microbial respiration of control samples has been subtracted. Vertical bars represent ±SD (n = 3).
