SOIL AERATION
....the best thing you can do for your lawn!
What is Soil
Aeration? Soil aeration is the mechanical removal
of small cores of soil from the lawn using an aeration machine. It is often
described as the most important thing you can do to create a healthy, thick and
robust lawn.
Why Should You Aerate Your Lawn?
Control Thatch Layer Development As
your lawn grows, it can accumulate a thick layer of thatch on the surface of
the soil. Thatch consists of a tight network of roots, zhizomes and/or stolons
and looks like a thick fiberous mat. This thatch layer acts as a barrier,
blocking the movement of air, water and fertilizers into the root zone. By
aerating your lawn annually the thatch layer is routinely broken up, and the
soil cores that are pulled up break apart on the lawn surface mixing with the
thatch modifying it into something closer to soil than thatch. The soil cores
are also full of microorganisms that help to accelerated the decomposition of
the thatch layer.
Reduce Insect & Disease
Incidence
The thatch layer is the perfect
environment for disease organisms, and insect pests. Chinch Bugs thrive in a
thick thatch layer, and a variety of pathogenic turfgrass fungi can be found
within a thatch layer. By keeping your thatch layer to a minimum you will
reduce turf damage from insects and disease without the use of any pesticides.
Reduce Soil Compaction Thatch
accumulation can also be dramatically accelerated when the soil of a lawn is
compacted. A compact soil results in the water and fertilizers sitting on the
surface of soil, and this causes the roots, rhizomes and stolons of the lawn to
grow on the surface, rapidly creating a thatch layer problem. Aeration breaks
up compacted soil allowing water, fertilizer and air to penetrate deep which
results in deep rooting of the lawn.
Reduce
Summer Drought Damage In a lawn with a compacted soil, most of the root
grow occurs close to the surface, and this creates a lawn that is highly
susceptible to summer drought. Aeration opens up the soil so water, fertilizers
and air can penetrate deep, encouraging roots to grow deep, resulting in a lawn
better able to tolerate the periods of summer drought.
More
Efficient Irrigation Compacted soils or a thick thatch layer inhibit
the penetration of the water into the soil. Thatch layers can become
hydrophobic, repelling water and making it almost impossible to get water down
into the root zone. On compacted or thatched lawns that have a slope,
irrigation water just runs down the slope rather than entering the soil.
Aeration opens up the soil and allows irrigation water to penetrate deep into
the root zone rather than running down the hill or into the storm sewer.
Improve the Results of Insect Control
Applications If you have root feeding insects in your lawn, like
European Chafer (white grub), then it is important to keep your thatch layer to
a minimum. Insect control products can become trapped in the thatch layer and
fail to get down into the root zone where the insects are feeding. This results
in poor insect control which generally translates into turf damage.
Reduce the Incidence of Weeds Many weeds can tolerate compacted soils
better than turfgrass. If your lawn is compacted it can results in an
environment that is more conducive to weed growth than turfgrass growth. By
aerating a lawn and alleviating any soil compaction, the weeds that perform
well in compacted soil lose the competitive advantage and the turfgrass
thrives.
Normally, an annual aeration is sufficient for good healthy
turf. Heavily compacted soils may require additional aeration. Our turf
specialist can advise you on what is needed for your lawn.
Your lawn
must have adequate moisture content in order for aeration to be effective, so
we may ask you to water in advance of aerating if seasonal conditions make it
necessary.
The aeration process will leave plugs of thatch and soil on
the lawn but these will decompose in a few weeks. Mow and water your lawn
normally.
