Love this form of aeration machine kindly on loan from the acedemy ground for use on our outfield to relieve compaction.This form of aeration can also be used on winter sports surfaces ,such as football and rugby .
linear aeration uses either discs as above or a kind of bend knife to score through the soil in a continuous line,creating channels for water to drain into and away from the surface.
We directed the machine directly towards the lowest part of the ground which also linked into the general drainage system.
The frost will also get into the lines meaning a slight opening and possibly lifting action which will give us some decompaction.
This machine is being widely used also as a means to try and slice up grubs,maybe wishful thinking but it’s a tool that could have some merit if used enough to combat chafer grub populations along with other tools such as nematodes,in the age of pesticide withdrawal.
Another positive of linear aeration is carbon dioxide out ,oxygen in which like all living things oxygen is a key to life even grass plants so a must in keeping a healthy plant and root system.
Obviously not everyone has the luxury of having such kit at there disposal but whatever kit you do have, whether that’s for the squares or the outfields/pitches we have up to end of January ,any later there is a risk of the lines re opening .
The discs give a similar advantage to mole ploughing are a similar to mole ploughing user in agriculture.
Sussex academy ground have previously mole plough there outfield to good effect but now have purchased a linear type aerator ,but if this is simply out of your budget it’s worth considering the mole plough, given you are experienced in the use .
