Soil aeration is the mechanism of improving the exchange of gases between the atmosphere and soil. Through soil microbial activity and plant root respiration, certain gases such as oxygen will be depleted in the soil, while others, such as carbon dioxide, will build up in the soil. [1] Lack of oxygen in the soil can impact plant growth.
A once-inviting lawn takes on a straw brown hue and a brittle crispy texture when winter arrives in cold regions. The new appearance is turf’s healthy response to frigid temperatures and limited ...

Photograph taken 21 March 2010 in Norwich, Vermont. Frost heaving (or a frost heave) is an upwards swelling of soil during freezing conditions caused by an increasing presence of ice as it grows towards the surface, upwards from the depth in the soil where freezing temperatures have penetrated into the soil (the freezing front or freezing boundary).
Linear aeration is an aeration process that allows water to penetrate the soil and to be retained in the proper amounts. [1] Additionally, it can also add organic nutrition and soil softeners (such as humus , topsoil , compost , sand or clay ) if necessary.
Aeration (also called aerification or aeriation) is the process by which air is circulated through, mixed with or dissolved in a liquid or other substances that act as a fluid (such as soil). Aeration processes create additional surface area in the mixture, allowing greater chemical or suspension reactions.
A core/plug aerator removes soil from the ground and leaves the core on the turf. This reduces compaction in the soil, and the holes can stay open for a long time allowing air, fertilisers, and water to reach the roots. Core aeration is suitable for heavy clay soils, and spike aeration is more suited to sandy or loamy soils.
The amount of water already in the soil; Soil temperature. Warm soils take in water faster while frozen soils such as permafrost may not be able to absorb depending on the type of freezing. [37] Water infiltration rates range from 0.25 cm per hour for high clay soils to 2.5 cm per hour for sand and well stabilized and aggregated soil structures ...
