When a search is done using SumaGreen,you can find Lawn 132012 in about every thread. Yet there is little testimony besides Lawn's 132012 brief expressions of "Try SumaGreen!" except that it has been through many studies. Before I try out the SumaGreen product can anyone direct to more supporting evidence. Can anyone share who these people are that developed the product. I wonder how well this one product (apart from a little N ) can supply and maintain a good environment for the soil.
