Aerated Steam Pasteurization

What Does Aerated Steam Pasteurization Mean?

Before diving into the details of aerated steam pasteurization, it is important to understand soil pasteurization in general. Soil pasteurization is a method used to mitigate soil-borne diseases, pest infestations, and weed growth that affect crop yield.

In line with this thought, aerated steam pasteurization is the use of air and stem to keep soil-based roots zones sterilized and free of pathogens. This process is also used in place of soil sterilization, in some cases, to avoid chemical usage in plant care.


Maximum Yield Explains Aerated Steam Pasteurization

Aerated steam pasteurization is useful in killing pathogenic organisms and weed growth in soil beds. Through the use of steam and heat, organisms that affect plant yield are destroyed. In order to benefit from the process, all root substrates need to be exposed to 212° Fahrenheit (100° Celsius) and the steaming needs to take place for at least a half hour.

Aerated steam is an eco-friendly option and often cited as the best means of pasteurization (and sterilization, too). Using aerated steam pasteurization consistently can ensure optimal results. There are three types of aerated steam pasteurization application: surface steaming, buried pipe steaming, and chamber steaming.

Surface steaming does not require pipe penetration for application; the equipment is placed right on the soil bed. Buried pipe steaming functions with the help of a pipe that penetrates the soil bed. Chamber steaming is ideal for propagation and is a popular choice for potted plants.
