Experimenting on the lawn.

Aeration works.

Aeration of lawn

"Aerating is the process of inserting holes in your lawn for better water absorption, nutrient absorption and helping in the process of eliminating thatch.

Concept of compaction. The water and nutrients can not penetrate the soil. The thatch from lawn mowing, instead of being decomposed and returned to the earth will just sit there inviting molds, mildews, disease and unwanted insects.

Aerating also enhances oxygen levels to your soil thus stimulating root growth and speeding up the decomposition of the thatch decomposing organisms. In removing the plugs of soil from your lawn this process severs roots, rhizomes and stolons. The affects of this stimulate your grass to produce new shoots and roots that will fill in the holes and increase the density of your lawn. It also increases your lawns drought tolerance.

When aerating your lawn, it is best to aerate on a day where the temperatures are milder and the soil in a moist condition, which will make the aerating process much easier. Aerating wet soil can be a real nuisance due to the fact that the plugs will get stuck in the hollow tines and can further compact you soil."
