Lawn grass cutting also breaks up compacted soil, allowing water and fertilizer to permeate into the root zone. Grassy areas submitted to constant foot traffic require lawn aeration more frequently than do out-of-the-way areas. The basic idea behind lawn aeration is that, like you, your lawn and the soil under it need to breathe. All negatively aerated floors will collect leachate and condensate and require special attention to drainage design. Positively aerated floors leave most of the liquid to pool and run off of the working surface and require more auxiliary drains. However, even positively aerated in-floor systems will collect enough water and solids to be a nuisance and will eventually plug if the design doesn’t allow for cleaning or they are neglected. Bottom up aeration systems are also less costly to operate than surface aeration.
Bottom up systems can also be powered by windmills, which are better for the environment and have zero operating costs, using only the power of the wind. Bottom up Aeration systems are 5-10 times more effective than surface aeration. These systems work by compressing oxygen and pumping it into the water through diffusers that lie at the bottom of a pond, lake, or dugout. Small bubbles are diffused into the deepest section of the pond, and as they rise up the water column, oxygen is transferred across the surface of the bubbles and into the water. This achieves total pond aeration from the bottom, up to the top regardless of the depth of the water.
