It would seem that in light of all of this, having an active microbrial soil with plenty of airy OM would be the best all around place to start in unlocking
various elements in the soil...
I hear a lot about products claiming to enhance soil microbes and "restore tired soils," like SumaGreen.
But, I can't find any studies that prove their claims. I've met with the owners of SumaGrow (makers of SumaGreen) many times and they have still not provided one scientific study to back up their claims. They like to show me a lot of corn and soybean pictures, but they have no turf or lawn data and no scientific research.
For a better understanding of soil microbiology and how SumaGreen-type products influence turf systems, watch this video:
It's from Dr. David Zuberer, a soil microbiologist from Texas A&M. He lends a lot of insight into all the claims that these new microbial products are making.
