Relationship of glyphosate application rate and the ratio of fungal to bacterial EL-FAMEs extracted from three soils after repeated glyphosate applications. The soils were: (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. Vertical bars represent ±SD (n = 3). Kruskal–Wallis nonparametric one-way analysis of variance found no significant differences in the ratios at all sampling date in all soils (alpha = 0.05).
