Not wanting to use roundup has nothing to do with reductionist thinking, I don't want to use it because I no it is a toxic chemical , end ofFocussing on glyphosate is just as much a distraction as "which drill is best?"
Classic reductionist thinking, looking at single issues rather than the whole
Yes, glyphosate IS a valuable tool that I rely on. I do have issues with its use, but nowhere near as much as I have with tillage
I stated earlier that I didn't believe zero till ( I REALLY don't like the term DD, from what I've seen here many seem to think that is just about not using a plough, but still using lots of HP & diesel & removing all straw ) is the ultimate farming system, but an important stepping stone to a more regenerative system. Part of that will be finding alternatives to glyphosate & most if not all herbicides. By focussing on glyphosate, you are making it ALL about glyphosate . . .
Plenty of work being done in the USA & Brazil with "organic" zero till, using green covers & crimper rollers
Here in Australia in certain areas that are climatically suited, "pasture Cropping" as pioneered by Col Seis & Darrel Cluff has a lot of potential, integrating livestock & cropping with no synthetic inputs
its the "concept" that is important, staying flexible & adaptable, rather than following a fixed set of rules & never deviating from that . . .
