"... Kong's team isolated three chemicals from crabgrass that affect the microbial communities in nearby soil and did indeed inhibit the growth of staple crops wheat, corn and soybeans. "The chemical-specific changes in [the] soil microbial community generated a negative feedback on crop growth," the scientists said, noting that the chemicals also would have a direct toxic effect on other plants."

So the allelopathy is directed SOLELY at the microbes, not a general herbicides to actual plants...

Now I'm curious ,,, what is the "negative feedback" all about???
The addition of compost may not even overcome that 'negative feedback' and end up being contaminated itself...
Interesting...
