Does liquid aeration really work? Do I need to aerate my lawn? Has liquid aeration been studied? These are all great questions and are answered in this video. Liquid aeration has taken hold as a simple way to make major gains in your lawn game and it is here to stay. For most homeowners, the thought of running an aerator is daunting. The barrier of entry for the end result may not justify the difficulty of the action. Rent an aerator, transport the heavy beast, fire it up and hold on tight, bounce around, break some sprinkler heads, get dirty, muddy, and look at the mess on your lawn…. Or spray.

Aeration is beneficial but not all lawns need it and most don’t at all.
NDSU says this “most lawns do not need it, lawns suffering from heavy foot traffic, excessive thatch above 1”, or grown on heavy soils will benefit the most.”

The benefits of aeration are this:

Root development
Water and Nutrient flow
Compaction relief
And thatch reduction

When soil becomes compacted, air and water do not flow as they should and mechanical aeration has always been the answer to this issue. Roots will not grow in conditions of heavy compaction and the roots are the key to healthier soil. Carbon dioxide can build when respiration is not present and this in turn can suffocate roots.

With this is mind we set out to do a true trial through University of Georgia and get some get baseline data. First of all, multiple tests on multiple plots were measured. The data was averaged out over each of the plots for the final numbers. I am mainly touching on the high points in this video as there is more to unpack and it will take subsequent videos to get all the info out. This is first year data and multi year studies are already in place to continue to view the overall result as time goes on. Liquid aeration, Air8, mechanical aeration are all part of a great lawn care program.

Here are some of the basics on the trial:
Location: Athens Turfgrass Research and Education Center, Athens, GA
Materials and Methods: Research was conducted on a mature stand of 'TifTuf' hybrid bermudagrass maintained at a 0.5 inch mowing height. The soil type was a Cecil clay loam with a soil pH of 5.9. Treatments were initiation on July 15, 2020 and were applied with a CO2 backpack sprayer.
Irrigated was applied weekly with an overhead irrigation system that provided 1.5 inches of
water per week. Turfgrass color (scale of 1 to 9), turfgrass quality (scale of 1 to 9), NDVI, volumetric water content
(% 3 averaged readings), and surface hardness (Clegg Hammer) were
recorded weekly throughout the duration of the trial. Four 1inch wide soil cores were removed to a depth of 6 inches at trial initiation and monthly thereafter. Cores were washed of all soil and roots were dried and weighed (g) to produce one measurement per plot. Water infiltration rates were conducted at trial initiation and monthly thereafter. A 6inch infiltration ring was inserted into the ground approximately 1inch. Tap water (444 mls) was poured into each cylinder and a stop watch was used to determine the amount of time it took for water to completely infiltrate the soil profile. Soil penetrometer readings to measure soil compaction deep within the soil profile were conducted at trial initiation and monthly thereafter. Three readings were taken in each plot an averaged together.
