So I am barely getting familiar with the things in this forum but here is the take... I'm out mowing one of my lawns that is treated by a 'big chem' company. The lawn is often over fertilized and the thatch layer is huge. Makes mowing a pain (along with the excess growth). Anyways as I was mowing I couldn't help but think a couple things. I read that the salt ferts can kill the biology in the soil. Hence less little guys to break down the thatch. What if using an AACT would eat up that thatch layer? Thinking: AACT are the aerobic ones right? The thatch layer should be good food for them, and still have enough air? Maybe brew an AACT from a compost made with a good portion of grass clippings, that way more of the little guys are the ones that break grass down? Spray and pray. Do you think this could help reduce the thatch layer? Yes the chemical applications will continue. Will the bacteria and fungi be able to live/thrive between applications or at all? Not sure. I'm not in any position to start dabbling with CT's at this time, but this may be a solution to a small annoyance caused buy the big chems? Now for the input... thanks in advance.
