Grass → Grasses, or more technically graminoids, are monocotyledonous, usually herbaceous plants with narrow leaves growing from the base. They include the "true grasses", of the Poaceae (or Gramineae) family, as well as the sedges (Cyperaceae) and the rushes (Juncaceae). The true grasses include cereals, bamboo and the grasses of lawns (turf) and grassland. Sedges include many wild marsh and grassland plants, and some cultivated ones such as water chestnut (Eleocharis dulcis) and papyrus sedge (Cyperus papyrus). Uses for graminoids include food (as grain, sprouted grain, shoots or rhizomes), drink (beer, whisky,vodka), pasture for livestock, thatch, paper, fuel, clothing, insulation, construction, sports turf, basket weaving and many others.
Lawn → A lawn aerator is a garden tool or machine designed to aerate the soil in which lawn grasses grow. Aeration improves soil drainage and encourages worms, microfauna and microflora which require oxygen.

Lawn problems
Lawn aeration constitutes two things: controlling lawn thatch and reducing soil compaction. Lawn thatch is a layer of dead organic tissue that deprives the lawn of much-needed oxygen. Soil compaction makes it difficult for grass to root and it disturbs natural rainwater irrigation. Watering the lawn the night before aerating can make it easier to aerate a very dense lawn.
It is purported that scientific evidence exists that aeration makes a measurable difference in the long-term health or quality of a lawn.
Also is great for the planting of new lawns.
Types of aerators
There are two types of lawn aerators. Spike aerators use wedge shaped solid spikes to punch holes in the soil. Core aerators have hollow tines and pull out plugs (or "cores") from soil.
Core/plug aerator vs. spike aerator
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. Then air, fertilizer, and water will be able to reach the roots, thus benefit the grass. Meanwhile, the soil cores left on the turf will help break down the thatches.
A spike aerator creates holes in the ground by pushing the soil sidewa ... Read the rest of this article
