When is aeration done

Aerating is a lot like mowing as you work back and forth across your lawn. Concentrate on any known problem areas, like pet runs or backyard baseball diamonds. Make several passes in different directions to help ensure optimal coverage and benefits.

After you finish aerating your lawn, let soil plugs or extra soil dry where they fall. They'll break down in rain or crumble the next time you mow, adding beneficial soil and organic matter to your lawn surface.

Right after aeration is a perfect time to overseed with premium Pennington Smart Seed and fertilize your lawn or do simple lawn repairs. Seeds and nutrients have direct contact with soil through the openings your aerator created and roots have fresh pathways for the things they need. The combination can help put your lawn on the fast track for quick seed establishment and thicker, lusher growth.

By adding aeration to your annual task list or doing regular compaction tests to check for need, you help ensure your lawn can reach its full potential for thickness, health and beauty. Pennington is committed to providing you with the finest in grass seed and lawn care products to help you achieve your lawn goals.

Simple, regular maintenance tasks go a long way in creating a thicker, healthier lawn. But jobs typically reserved for once a year can play a significant role in supporting smaller steps taken across the months.

For many homeowners, aerating lawns to relieve soil compaction and enhance grass growth is a regular annual task. Almost any lawn can benefit from aeration when it's timed well and done properly. Why Aerating Helps Lawns Grass roots need air, water and nutrients to grow thick, deep and strong.

Core aerators pull small plugs of soil to the surface. When Lawns Need Aeration It may not seem your lawn could get compacted, but it happens easier than you may think.

When to Aerate Your Lawn As with most larger lawn projects, such as planting grass seed , it's best to aerate during or right before the time your grasses reach their peak time for natural growth. The process of lawn aeration can be as simple as poking holes in the soil here and there so-called "spiking" , but this would work only for superficial cases. For those in greater need of lawn aeration, this haphazard approach will not be sufficient: you will need to perform core aeration.

You should also faithfully remove as much lawn thatch as you can in fall by raking deeply, rather than just skimming the autumn leaves off the top of the lawn. Lawn aeration also breaks up compacted soil, allowing water, air, and nutrients to permeate into the root zone. Grassy areas submitted to constant foot traffic or, worse, car traffic require lawn aeration more frequently than do out-of-the-way areas.

Lawn aeration should happen when grass is at its peak growing period so it can recover quickly. Aeration may be undertaken in the late spring or early summer for warm-season grasses , such as Bermudagrass. But for lawns planted with cool-season grasses such as Kentucky bluegrass , early spring or fall is the best time for core aeration.

You can easily rent a lawn core aerator from a big box store or rental center. Since you should not need to aerate your lawn very frequently, it makes better financial sense to rent rather than purchase the aerator. Typically, if you don't see any issues with your lawn, you can aerate every two to three years. However, for high traffic areas or if your lawn grows in heavy clay soil, annual aerating may be necessary.

This lawn aeration equipment will pull plugs, or "cores" thus the name of soil out of the ground, letting air in. These plugs should be two to three inches in depth. Such a plug should be pulled out of the lawn at about every three inches. The plug removal process is facilitated by watering the lawn the day before, but don't water to the point of muddying the soil. Leave the plugs on the grass: they'll break down and add nutrients to the soil.

Water every two to three days after aerating. Alternatively, hire a lawn service to do the job of lawn aeration for you. For more on dethatching, please consult this information on raking leaves. It should be noted that course bubble diffusers can require twice as much air to operate as fine bubble diffusers. A sub-surface aeration system consists of a compressor or blower, a valve system to distribute air and finally a diffuser located on the bottom of the lagoon.

Surface aeration of wastewater is used in lagoon or pond treatment systems. Equipment used for wastewater surface aeration includes low waterfalls, jet fountains and spray nozzles. These can be fixed or on pontoons. Wastewater comes into contact with the air through the agitation created when it is sprayed or transported. This type of aeration creates the maximum possible mixing and a high level of oxygen transfer to the wastewater it comes in contact with.

This is an example of a fountain used for surface aeration. While it does a great job of mixing the water near the surface of the pond, it does not mix near the bottom. Wastewater aeration is typically used during the secondary treatment process. This process is most often an activated sludge process.

Aeration in an activated sludge process is accomplished by pumping air into the tank or lagoon. Proper aeration promotes the growth of microorganisms or microbes in the wastewater. The microbes feed on the organic pollutants and form flocs which can easily settle out.

The flocs are allowed to settle out in a separate settling tank or lagoon. The flocs of bacteria that settle and accumulate on the bottom of the tank or lagoon form activated sludge. The activated sludge can then be recirculated back to the aeration basin or lagoon to increase the rate of consumption of pollutants. Wastewater aeration is also used in tanks and lagoons used for storage. Examples of these storage tanks and lagoons would be ones used as sludge holding and flow equalization.

In these portions of a wastewater treatment system tank or lagoon it is important to maintain the living microorganisms. If the microorganisms begin to die, the wastewater will become septic and odor will start to be an issue.

Expandable rubber membrane diffusers produce a laminar flow of bubbles.
