From what I recall from my conversation with him, it only worked on seapers and I didn't ask about soil types. He did say that it was pretty much 100% successful. The application rate was pretty high at about 50lbs per 3ft x 3ft area and results were seen within a week. I asked him if he had heard of this site (he said no) and then I tried to explain that if this really did work, allot of people would be happy. I will call him tomorrow and see if he would join the forum or mind if I give out his contact information. Would be much better than me trying to play the middle man.
I'm really interested to see if using a lower application rate over time would have the same affect. Of course the PH would have to be closely monitored.
