People didn't remove all the weeds before glyphosate. Nor did all the work manually.


they used a culivator. Basically a hoe you pull behind the tractor. this of course burned a lot more fuel [read CO2]


And chewed up the soil.


What do you mean they didn’t do it manually?


There are several types of weed removal equipment one can plug on a tractor at the different stages of the life-cycle of the crops.
