Improving the aeration within the soil is especially beneficial to lawns that are growing in clay or compacted soils. - SAFE FOR ALL LAWNS - Liquid aeration can be done anytime during the growing season. - NO NEED TO MARK SPRINKLER HEADS - Liquid aeration covers the entire lawn. There is no need to mark sprinkler heads, invisible fences or cable lines. - DEEP PENETRATION - With liquid aerate the soil structure is split at a much smaller scale, allowing for deep penetration of water; roots will, in turn, follow, making nutrients available that were previously unreachable by the plant. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09S28Y9C8 | | Best Sellers Rank | #61,101 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,447 in Garden Fertilizers | | Brand Name | Yard Mastery | | Coverage | {'1 Gallon': 'up to 21,300 sq ft', '2.5 Gallon': 'not specified, but equivalent to two 1-gallon bottles', '5 Gallons': 'not specified, but equivalent to five 1-gallon bottles', 'Quart': 'not specified, but equivalent to 0.25 gallons'} | | Customer Reviews | 4.2 4.2 out of 5 stars (157) | | Item Form | Liquid | | Liquid Volume | 4 gallons | | Mixing Ratio | 6-9 ounces per 1,000 sq. ft. | | Model Number | Air 8 | | Number of Items | 4 | | Number of Packs | 1 | | Part Number | YM-AIR4G | | Specific Uses For Product | Root Development | | Target Species | lawn grasses | | Unit Count | 512 Fluid Ounces | ## Product Details - **Brand:** Yard Mastery - **Item Form:** Liquid - **Liquid Volume:** 4 gallons - **Number of Packs:** 1 - **Specific Uses For Product:** Root Development ## Images ![N-Ext Air-8 Liquid Aeration Bio-Stimulant, 4 Gallon Pack - Image 1](https://m.media-amazon.com/images/I/51UCVh0ZvoL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - [N-Ext] Air-8 - Liquid Aeration Bio-Stimulant with Humic Acid - 4 Gallon Pack (512 oz) Covers up to 85,200 sq ft - Break Up Soil and Loosen Topsoil to Increase Water Penetration and Encourage Deeper Rooting for More Oxygen into The Topsoil - Ortho Dial N Spray Hose-End Sprayer for Liquid Weed and Insect Killer, Fungicide, Fertilizer with 14 Dilution Settings - [N-Ext] Humic12 - 12% Humic Acid for Lawns Bio-Stimulant Liquid Fertilizer - 4 Gallons Covers 56,888 Square Feet - Increased Root Growth, Chlorophyl Content, Nutrient Uptake, Soil Structure, Water Retention, Plant Quality, and Mineral Chelation. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/420933749-n-ext-air-8-liquid-aeration-bio-stimulant-4-gallon](https://www.desertcart.co.za/products/420933749-n-ext-air-8-liquid-aeration-bio-stimulant-4-gallon) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-17*
