Linear aeration is a relatively new aeration process; it allows water to penetrate the soil and to be retained in the proper amounts. Linear aeration also adds organic nutrition, soil softeners (humus, topsoil, compost, sand, clay, etc.) if necessary.

Gardens
In linear aeration, the necessary organic matter is added on top of the soil surface, between plantings. The grooves are then cut into the soil to let the amendments and additives enter the soil; and recovered in the same passage.
Lawns
Linear aeration also alleviates excessive water in lawn areas. In linear aeration, the necessary organic matter is added on top of the turf. Next, grooves are cut into the turf to let the soil additives enter the soil; the grooves are recovered in the same passage.
