Does increase herbicide use impact on key soil biological processes? locations
Aims

It assess the impact of repeat applications of herbicide on residue levels and the impact on soil biology and crop production.

Key messages

Glyphosat, Trifluralin and diflufenican residues, plus glyphosate metabolite AMPA are frequently detected at agronomically significant levels at the start of the winter cropping season.

The risk to soil biological processes is generally minor when herbicides are used at label rates and sufficient time is given for them to dissipate before re application.

Further research is needed to define critical thresholds for glyphosate, trifluralin and diflufenican and AMPA and the potential impacxts to soil function and crop production.
