Product Description:
Air-8 Liquid Aeration dives down into the soil breaking bonds between molecules which creates space. Every bond that is broken creates more space (aka greater soil surface area) where grassroots can then spread and grow.

This also pulls down moisture and carbon since humic acid is included in the mix. If you have hard, compacted clay soil, Air-8 liquid lawn aeration is an excellent alternative to the butt-kicking you get from mechanical aeration.

One thing we know: 95% of homeowners cannot or will not rent a mechanical aeration machine. It's quite the hassle even to go and get it, especially if you don't have a truck to get it home in. On top of that, it's quite the workout. Since so many people are not able to mechanically aerate, liquid lawn aeration is your next best choice.

Now, we do still recommend mechanical aeration as a way to make a good seedbed if you are doing an overseeding. Poking all those holes really does help keep everything from washing away. Plus, running an aerator is a butt-kicking that everyone needs to experience at least once in their life! However, if you are not seeding, then just spray down Air-8 and you will get great results and never need to rent an aerator again.

It is a good idea to water the lawn the night before you apply and then again after your application, water it in with ½” of irrigation or rainfall. The more soil moisture present before and after application, the more effective liquid Air-8 will be.
