Can liquid aeration replace core aeration in my lawn?

Question:

Can liquid aeration replace core aeration in my lawn?

Answer:

There is no published peer-reviewed research that shows liquid aeration is a viable replacement for core aerification to reduce soil compaction in the lawn.

Liquid aeration products are often sold as soil conditioners and promoted as an alternative to core aeration to relieve soil compaction. While the ingredients vary by product, most contain materials such as humic acids, seaweed extracts, and nutrients that support plant growth. These products are sprayed on the lawn and have shown to increase rooting and soil moisture retention while reducing surface hardness compared to untreated areas. However, liquid aeration products did not significantly improve soil compaction or help water move into the soil over the long term. As a result, liquid aeration should not be considered a replacement for proven practices such as core aeration.
