Subsurface Aeration

In an attempt to break up some of the deep-rooted compaction in some of our greens, we have this week hired a Robin Dagger.

The Robin Dagger has a single 30 mm x 600 mm tine, which is driven into the ground by an air hammer.

Once the tine is fully inserted a burst of compressed air is released horizontally in three directions at the base of the tine.

The air pressure at the point of release is around 100psi. 

The compressed air creates fissures in the soil, alleviating compaction and allowing water to penetrate more deeply.

Below is a short video of the Robin Dagger working on Ravelston’s 5^th Green.
