Weed Control Report: What is GLYPHOSATE doing to my food?

This is a semi-formal report of an experiment comparing the effects of tilling, cover crop, and glyphosate-based early season weed control strategies on the elemental composition of several crops, with regenerative organic and conventional fertilization as a second variable. In crops that had an unfavorable response to earlier glyphosate treatment, a rich compost made from coffee grounds and deciduous leaves reversed most of the unfavorable effects. Conventional fertilizer continues to be associated with elevated nickel levels, and regenerative management with elevated nutrient levels.
