What is the zone of aeration.
Aeration is an essential aspect of lawn care. Core aeration is a type of lawn aeration whereby a machine (a lawn aerator) with hollow tines mechanically removes plugs or "cores" of soil and thatch from a lawn. Core aeration reduces soil compaction, creating a channel through which oxygen, water, and nutrients can penetrate the soil.
zone of aeration, or unsaturated zone. Eventually the water reaches a depth where the pore spaces are already filled, or saturated, with water.

Groundwater is water that exists underground in saturated zones beneath the land surface. The upper surface of the saturated zone is called the water table. Contrary to popular belief, groundwater does not form underground rivers. It fills the pores and fractures in underground materials such as sand, gravel, and other rock, much the same way that …Aeration is the process by which air is circulated through, mixed with or dissolved in a liquid or substance. … Aeration brings water and air in close contact by exposing drops or thin sheets of water to the air or by introducing small bubbles of air and letting them rise through the water.Sep 1, 2023 · Quick Reference The subsurface zone between the ground surface and the water table, where the pores in soil and rock contain both air and water. Also known as unsaturated zone, vadose zone, or zone of aeration. From: aeration zone in A Dictionary of Environment and Conservation » Subjects: Science and technology — Environmental Science Water table is the term for the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with groundwater, [1] which may be fresh, saline, or brackish, depending on the locality. It can also be simply explained as the depth below which the ground is saturated.The upper limit of the zone of saturation Below the zone of aeration. Usually a replica of the surface topography.
