Soil aeration
Soil aeration Is a rapid exchange of oxygen and carbon dioxide between the soil pore spaces and the atmosphere, in order to prevent efficiency of oxygen and toxicity of carbon dioxide in the soil air. Soil aeration influences the availability of many nutrients. Aeration is the process by which air is circulated through, mixed or dissolved on liquid or substance that act as a fluid. It helps the roots grow deeply and produce a stronger, more vigorous lawn. The main reason is to alleviate soil compaction. A lawn is an area soil-covered land planted with grasses and other durable plants like clover, which maintained at a short height with a lawn mower. Commonly referred to as part of of a garden.
