Most people are aware that plants use Carbon Dioxide (Co2) and releases oxygen (o2), which in turn, we inhale and exhale Co2. This is a symbiotic relationship between plants and humans. The most significant area of a plant that requires oxygen; where oxygen benefits the plants most is the root zone.

Allowing the plant's root system to receive the maximum amount of oxygen possible will encourage nutrient uptake, leading to faster growth rate by up to 30% as well as increased yields.

We can take the plant-human symbiotic relationship to another level by increasing the amount of oxygen available to the plant's root zone. Increase the plant's root zone oxygen and the plant will reward you by growing faster and being more productive.

On the contrary, if you fail to supply the root zone with oxygen, the plant will fail to grow vigorously and output high yields.

What it means to oxygenate nutrient solution or grow media
Oxygenating your nutrient solution in a hydroponics application or your grow media, including soil and soilless (Perlite, Clay Pebbles, Rockwool) means to combine o2 with H2O for nutrient solution or allowing o2 to flow through porous grow media.

Before we proceed to the specifics of oxygenating soil and soilless culture root system, It's important to understand how o2 combines its self with H2O. Oxygen is a form of gas found in the atmosphere. Dissolving o2 into water is called a mass transfer process. To accomplish mass transfer, there must be two required parameters.

Firstly, there must be a driving force; the difference between the amount of o2 present in the liquid, and the maximum levels of o2 the water can hold. What this means is water has a threshold of o2 concentration is can hold. This is often referred to as solubility. Henry's Law governs the solubility of a gas substance into liquid.

Secondly, there needs to be an interfacial surface area, the point of contact or interaction between the liquid and the gas. Read on to get a better understanding of what this means for your particular cultivation method.
