wish I hope and prayed to have something I could hear that may help save my back. The only thing that has helped is organic matter tilling it in and adding the soil living organisms. I live in the NE and have a mix of clays. There is the creamy yellow that is on top of BIG ROCK DEPOSITS (size of a small car) with some cracks between chunks. Everything too close to the clay dies until larger chunks of rocks are removed with some clay and water drains. THEN the tilling, organic matter and amendments work. I think the charcoal and neutralizers work their magic and help. At 2018, I have a 1/2 steel pipe cut to a point to do the aeration deeply poking at least a foot down and I do add all the good stuff I can get down and add the gypsum to help keep it down. I does help break the clay into smaller bites with compost I buy by the 10 wheel truck load. I have beautiful soil in my garden and flower beds. I did wish science had made some progress since your notes started 11 years ago. If anyone wants to have a trial with their product on my lawn I will be glad to offer my free space. Sorry I haven't found a magic bullet but I do use Ivory and sudsy ammonia to fertilize and kill the bugs. Love to all the young who are ready to take on the challenge and God bless the soil scientists who are still trying to solve it. My 50+ acres are available and with a little love we can grow a 10 foot beautiful corn stalk or 4'+ hay field. Thanks everyone for your thoughts.

Never used the product. Too cheap! Our city compost center rents a lawn spreader if you want to use their finished compost to spread some on your lawns. This is assuming you have a P/U to haul it home and a garden tractor to tow the spreader. I have tried it by hand a few times (I said I was cheap,) but there were a few burned spots where I got carried away. It is all better now but for a while it looked funny. I am lazy and let the earthworms till the soil for me, what grass I have left that is. Foghorn Leghorn National Anti Grass League Here is a link that might be useful: Lawn forum

Mostly these products are soap, a surfactant, that allows water to penetrate soil easier by reducing the surface tension in the water, same thing that removes grease from pots and pans and dishes. Rather than spending money on these products add organic matter, compost and other vegetative waste, to your soil to accomplish the same thing.

We did use the liquid soil aerator, and it worked great for us. The back of my yard was too shady for grass, so I bought some bulbs to plant last winter. You couldn't get an inch down in the soil. My husband tried a power drill with a wide drill bit, but even that wouldn't go into the soil. I ordered the aerator on line, not expecting much. I am happy to say, we are now planting bushes and shrubs in the back with no problem. Also, we have used this in our entire yard, and our grass was beautiful last year. Now, we did use it more than once. I think all together 4 times in the trouble spots, but after the first application, you could tell a very noticeable difference.
