Soils become compacted over time, desiccation (drying out) or weight are based on Earth. This reduces the amount of free space between soil particles, called pores and leaves less space available for water and air. Not only this makes it more difficult for soil to hold water, it also prevents grass roots well absorb nutrients needed to feed the shoots of the surface.
Regular aeration is an important part of growing a lawn healthy and attractive. In the summer, hot, dry weather can quickly dry out and brown grass. Once a lawn has browned, ventilate the affected area provides essential roots water and grass plants will quickly become green once again, even without watering. In the fall and winter months, soil can become sealed due to an increase of compaction caused by climate change. Aeration down sealed soil and water is able to move freely through the Earth, again preventing pooling at the surface. Regular aeration allows to fight against the effects of the seasons, ensuring that a lawn is at its best no matter what the climate conditions.
A common method of aeration is solid tining, or fortification, which can be done with a range of gardening or a spike lawn aerator. A mechanical or electrical lawn aerator is suggested for the major centres, such as with a fork is extremely difficult. However, fortification is not the best method to increase drainage of soils, in all as it compresses the soil rather than removing it.
An alternative to the fortification is to use a hollow tiner. Hollow Tining, also known as the core, removes a lawn soil cores by forcing a hollow steel component in the soil. When the tine is relieved, a small core of soil is removed, creating holes for water and air to move through. A hollow toothed lawn aerator is preferable to a solid tiner nucleus, as the removal of the individual soil cores creates space for air and water to permeate more freely across the Earth. It is noted that hollow toothed aerators leave small carrots on a lawn surface and thus as being little attractive, these need to be commissioned as they may contain some bad seeds which germinate if left unattended. They may also become connected with the Earth and have to be cleared a number of times while aerating a lawn. That being said, hollow tining break stubble, a matted layer of decomposition of grass roots which may deprive a lawn of oxygen, much more readily than solid or spike tining.
