The above table shows the misconception about core aeration and its benefits.  Though core aeration, in theory, is somewhat beneficial to the turf, the fact is that it’s not efficient at all.  In this table we have highlighted the two most popular styles of aerators in use, and you can see that with each pass they are at best impacting 5% of the turf.  So to truly aerate just 50% of a yard or sports field, you would need to go over the same area 10 to 18 times, depending on the type of aerator.  That is where SoilTech comes in.  Since SoilTech is a liquid it will cover 100% of the area and penetrate 8-10”, giving you no reason to buy or rent inefficient aerator.  Now you know the truth!
