I call this the “Yin & Yang” combo because it impacts two of the most common issues I hear - thatch and compacted soil. If that describes you, this is your tonic. 

Spray this every 3 weeks any time of the year via a hose-end sprayer or pump sprayer. Apply when temps are over 60F and ideally over 75F or even 80F.

Below is more information on each product.


N-Ext Air-8™ 0-0-5 Liquid Aeration is designed to break up and loosen topsoil and encourage deeper rooting to drive more oxygen into the topsoil profile.

What if I told you that mechanical aeration isn’t the best way to loosen up the soil and allow grass roots to spread? Blasphemy, right?

If the lawn care world was the Catholic Church I’d be kicked out quicker than Martin Luther.

But think about it like this, the purpose of aeration is to produce more surface area in the soil, right?  

Air-8 does that by driving down into the soil and breaking up bonds between all the molecules down there creating space. Every bond that is broken creates more air space (aka greater soil surface area) where grass roots can then spread and grow.

Now, I do still recommend mechanical aeration as a way to make a good seed bed 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.

Okay so what is Thatch?

Thatch is the layer of dead turfgrass lying between your healthy turfgrass and soil/root system. It usually consists of stems, stolons, rhizomes, and roots that haven’t decomposed.

Why is this bad?

If it becomes too thick, the thatch layer blocks air, water, and nutrients from seeping down into the root system, which are needed to help your grass thrive.

Having this layer is also bad because it promotes diseases and insect infestations in your lawn. Reason being all those nutrients and water are just hanging out in the thatch layer which the microbes and insects treat as a buffet.

How does D-Thatch help this?

D-Thatch is used for one thing and one thing only. To chew through that top layer of thatch and get good grass to soil contact.

We also want thatch to go back into the soil and turn into nutrients for the lawn. We don’t want to scrape it off and send it to the dump.

What’s great with the D-Thatch is that it accelerates the decomposition of those stems, stolons, rhizomes, and roots so they can go back down into your soil and become nutrients for the lawn.

N-Ext D-Thatch™ focuses on composting thatch faster by encouraging microbial activity at the soil surface and increasing heat. This exothermic release by increased soil activity will breakdown thatch from the soil level up. Thatch is quickly reduced and the organic matter is captured as a food source for your turf.

If you have a dog that kills spots in the lawn from urine, dead or brown spot areas that were diseased and now attempting to recover, or even grass clippings leftover on the lawn - you can use D-Thatch to eat through the dead grass and deliver those nutrients right back into the soil!

The recommended application rate for this “Yin & Yang” combo is a mixture of Air-8 and D-Thatch both at 6 oz per 1,000 sq ft.

With this product, you’ll receive one 2.5-gallon jug of each product.

  • 1 gallon = 128 oz
  • 2.5 gallons = 320 oz

At the app rate of 6 oz/1,000 sq ft, you will get:

  • 21,300 sq ft of coverage from a single gallon
  • 53,300 sq ft of coverage from a 2.5-gallon jug

For a 5,000 sq ft lawn, this means you will get ~11 total applications: 

  • 6 oz/1,000 sq ft x 5 = 30 oz
  • 320 oz/30 oz = 10.6 total applications of both RGS and Air-8

Keep this in mind when you decide how much you need. If your yard is not that big, consider splitting with a neighbor or family member.
