well....the whole idea behind GMO’s is no-till farming.
You kill everything in the field with Roundup, except your grain which has been modified to resist Roundup.
It then grows to maturity in a field, taking in water and nutrients in a field spiked with Roundup.
These results seem wholly logical to me.
That’s how all agriculture works. Weeds are killed either by chemicals or by cultivation. Round-Up isn’t perfect, but it beats the Hell out of 2,4-D or triazene herbicides which it largely replaced.
Except that glysophate breaks down in soil as scientific tests have shown for 40 years: http://www.jstor.org/stable/4042278?seq=1#page_scan_tab_contents
so do you want to be poisoned by chemicals or die of global warming?
