Relative importance of the effect of 2,4-D, glyphosate, and environmental variables on the soil microbial biomass
Two post-emergence herbicides (glyphosate and 2,4-D) were applied at field application levels to tilled field plots in a mixed crop** area in south-central Alberta. The effects of these chemicals on certain ...
