Reducing Compaction
I recommend the Air2g2 machine as the best form of aeration to reduce compaction, this will break the
compacted layer and open up channels within the soil profile for air, water and nutrients to move through.
Aeration increases pore space which will aid root depth and strength which will help increase the quality of
pitch/green playability. It is important you vary the depth of tine/probe you use when aerating. If the same
depth is used over a long period of time you will create a compaction layer at that depth in the soil profile.
Most soil compaction occurs within the top 6 inches of the soil surface, but can vary from site to site and it is
vitally important to take regular core soil samples to assess compaction levels and overall health of your soil.
Top dressing with sand can help with drainage and compaction. Top dressing certain soils with sand can help
to form a protective layer over the indigenous material, which will help to reduce the effects of compaction on
the underlying soil.
However, good maintenance plans and practices are also needed to keep your turf and soil healthy, such as
mowing at the correct height and frequency, scarification to remove any organic material (thatch), and a
tailored feeding programme for the site will all help keep the sward healthy all year round.
