About This Product

Liquid Aeration That Replaces the Plug Puller

N-Ext Air-8 is a liquid soil amendment that reduces compaction at the particle level using 8% humic acid. The humic acid works between soil particles to create space for oxygen, water, and roots to penetrate deeper. The result is similar to mechanical core aeration but without renting equipment, pulling plugs, or disrupting the lawn surface.

One gallon covers up to 21,300 square feet. Applied monthly during the growing season, Air-8 delivers cumulative compaction relief that matches or exceeds a single annual core aeration.

Who Air-8 Is For

Homeowners with compacted soil, clay-heavy ground, or lawns that puddle after rain. If water pools on the surface instead of soaking in, or your soil probe meets hard resistance within the first few inches, your soil is compacted and Air-8 addresses that.

For severely compacted soil on new construction sites or heavy clay, one mechanical core aeration followed by monthly Air-8 applications is the most effective approach. For established lawns with moderate compaction, Air-8 alone handles it.

Part of the Soil Activator Package

Air-8 is the compaction component of the N-Ext Soil Activator Package alongside RGS, D-Thatch, and GreeNe EfFect. RGS drives roots into the space Air-8 creates. D-Thatch breaks down thatch at the surface. GreeNe EfFect provides color. Together they address the full soil health picture from the surface down.

01

When to Apply

Apply monthly during the growing season, spring through fall. Air-8 works best when soil is warm and biologically active. Results are cumulative, so consistency matters more than timing. Start in early spring and continue through fall. Each application builds on the previous one to progressively loosen compacted soil.

02

How to Apply

Apply with a backpack or battery-powered sprayer. Water in after application to move the humic acid into the soil profile. Pairs naturally with RGS in the same tank for a root growth and soil loosening combination. Apply evenly across the entire lawn, focusing on areas with visible compaction or drainage issues.

03

What to Expect

Improved water absorption within the first 2 to 4 weeks, especially in areas that previously puddled or showed runoff. Deeper rooting visible when pulling soil plugs after 2 to 3 consecutive applications. Full compaction relief builds over a complete growing season of monthly applications. This is a cumulative process, not a one-time fix.

Frequently Asked Questions

Answers to the most commonly asked questions about this product:

What does liquid aeration actually do?

Air-8 uses 8% humic acid to break apart compacted soil particles at the molecular level. This creates space for oxygen, water, and roots to penetrate deeper into the soil profile. The result is similar to mechanical core aeration but without pulling plugs, disrupting the lawn surface, or renting equipment.

Does this replace core aeration?

For most residential lawns, yes. Liquid aeration applied monthly throughout the growing season delivers cumulative compaction relief that matches or exceeds a single annual core aeration. Severely compacted soil (new construction, heavy clay) may benefit from one mechanical aeration followed by a liquid aeration program to maintain the improvement.

How often should I apply Air-8?

Monthly applications during the growing season produce the best results. Each application builds on the previous one. Most homeowners apply spring through fall, which gives 4 to 6 treatments per year.

Can I mix Air-8 with other products?

Yes. Air-8 pairs naturally with N-Ext RGS for a root growth and soil loosening combination. It is also part of the Soil Activator Package alongside RGS, D-Thatch, and GreeNe EfFect. It mixes well with most N-Ext liquid products.
