Liquid Aeration Products: Experts Skeptical of Claims

Three UGA scientists reviewed surfactant-based “liquid aeration”:

Dr. Tim Smalley: Works on hydrophobic sands (golf greens); no data for clay landscapes; concerned about cost/longevity.
Dr. Dave Kissel: Many such products fail; demands university research before spending money.
Dr. Clint Waltz: Tested a similar product—no change in soil bulk density; green-up came from nitrogen in the product, not aeration. Core aeration remains the only proven relief for compaction.

Save your money; rent a core aerator instead.
