Not sure where you get your info from but SumaGreen does build up OM in the soil.
I was just writing to say after the rainfall these past few days after another treatment of SumaGreen my lawns are 'BANGIN'. The difference in one week is crazy. I have a few clients that do not water their lawns so I think that had something to do with it also but several people mention to me that this was the best their lawn looked at the end of a dry summer.
I wish I had taken before pics on the rough looking lawns. I will be doing a few new seed lawns soon so I am interested to see it work on them too
