turf builder weed & feed is the process by which air is circulated through, mixed with or dissolved in a liquid. Gets heavy use, such as serving as the neighborhood playground or racetrack. Children and pets running around the yard contribute to soil compaction.
Utilizing extremely small bubbles or drops increases the rate of gas transfer due to the higher contact surface area. The pores which these bubbles pass through are generally micrometre-size. Ceramics are suitable for this purpose, often involving dispersion of fine weed grass air or gas bubbles through the porous ceramic into a liquid. The smaller the bubbles, the more gas is exposed to the liquid increasing the gas transfer efficiency. Diffusers or spargers can also be designed into the system to cause turbulence or mixing if desired.
