I remember hearing about a concept of - starting a new lawn out on Corn Meal because it is easily digestted. As the soil microbe populations increased and the variety of microbes increased you would then apply Soybean Meal, because the lawn would now be able to turn that into plant food effectively. This concept if true would apply to using soil biology instead of mechanical processes to keep thatch under control. It doesn't appear that the idea of getting the correct microbes in the correct habitat to help digest thatch is a very common one. I would think the CT folks would have been interestted in this idea and would know what species and foodstuffs work best for thatch. If anyone out there has any insights or interesting articles on research that address soil biology and thatch, perhaps they could be shared here. Thanks for your help.
