With the soil compaction and conditions in our area, either Liquid or Mechanical Core Aeration is a good idea at least once a year.

What is the difference between Mechanical Core Aeration and Liquid Aeration?

Mechanical core aeration pulls plugs from the soil opening up holes for root growth and drainage, as well as leaving the plugs at the surface level - bringing beneficial bacteria up to the thatch layer to bring out microbial balance.

Liquid Aeration uses carbon substances like ash, humic shale, kelp, and biochar in solution with soil nutrients to create micro-fissures (think "pop rocks") and to establish healthy bacteria that bring about better nutrient retention, water holding capacity and healthier soil and healthier grass.


In the past, the jury was out on the effectiveness of liquid aeration, but a recent study at the University of Georgia Turf Program is showing that liquid aeration is as effective as mechanical aeration for water retention, nutrient retention, and producing healthier soil, however, core aeration remains the preferred treatment for severe soil compaction. Additional benefits can be seen from having BOTH core and liquid aeration.

Advantages of Liquid Aeration:

  • No need to mark sprinkler systems, invisible pet fences, pop-up drains, shallow cables, and other underground lines.
  • No messy plugs
  • Pets (and people) can go out on the lawn immediately after the application
  • Liquid aeration creates fractures within the soil and encourages greater rooting.
  • With liquid aeration, 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.
  • Liquid aeration can be done anytime during the growing season.
  • Liquid aeration covers the entire lawn
  • Liquid aeration can be done in areas with surface roots that may not be accessible with an aerator.


The goal of aerating a lawn is to get more oxygen, water, and nutrients into the root zone. Improving the aeration within the soil is especially beneficial to lawns that are growing in clay or compacted soils.


Advantages of Mechanical Core Aeration:

  • If a lawn has HEAVY traffic and is severely compacted (commercial properties, ball fields, lawns that have vehicle traffic), mechanical aeration is a better option.
  • Sodded lawns with heavy thatch will see more benefits from mechanical core aeration.


Timing

The liquid aeration can be done in both the spring and the fall (and also the summer). Mechanical aeration can be done in both the spring and fall depending on weather and turf conditions, but we do NOT want to do core aeration when the air is too hot and dry, since opening up holes to the roots with hot, dry air can cause damage to the grass roots.
