SOIL STERILIZATION
Soil Sterilization and Steaming
Using a commercial soil sterilization equipment is a highly effective way to prepare soil in your greenhouses, high tunnels, or open fields for planting. It uses steam to rid the substrate of fungi, diseases, invasive species, weed seeds, and other harmful biological materials. Soil Sterilization before planting gives you larger, healthier plants with improved yields.
Soil Sterilization is a tried and true method to organically control diseases, insects, weeds, and contaminants from soil, growing media, and mushroom substrate. Steam is much less hazardous than chemical applications and can be used to pasteurize the soil, clean growing containers such as pots, benches, and trays, and sterilizing mushroom substrate before inoculation.
Weeds & diseases can become resistant to chemicals over time, but steam will always remain effective. Steam works the same yesterday, today, and tomorrow. Utilizing steam, instead of relying on chemical control methods or cleaning, is less hazardous, frees up labor for more productive activities, gets you planting faster, and can help improve your overall yield.
Why Steam for Eliminating Greenhouse Weeds?
Why do some of the fastest growing nursery operators use steam to sterilize the soil in their greenhouse beds? Low-pressure steam is the original organic and environmentally friendly way to control harmful diseases, nematodes, pathogens, and weed seeds.
Also, weeds cannot become resistant to heat over time like they do with certain chemical applications. Because weeds do not become resistant to this method, steam eliminates greenhouse weeds yesterday, today, and will continue to eliminate weeds in the future.
Steam Flo® Skid Mounted Units

USGR line of all-electric steam generators utilize immersion heating element(s) inside of the vessel to create steam. Unlike fuel fired models, these units produce no open flame, fumes, or exhaust, making them ideal for indoor applications where venting is not possible or hinders the portability of the unit.
A low-pressure steam generator is the perfect solution for sterilizing soil. Steam generators are easy to operate, can be fully operational in minutes, and are available as stationary or portable units. Steam generators can use either diesel, natural gas, or propane as their fuel source, and require a garden hose water source and 115V electricity. The steam-generator is then set up with a steam hose and steam sock to evenly distribute the steam into the soil.
The steam sock is laid on top of the soil and covered with a heavy tarp, and the edges of the tarp are weighted down. Steam is then delivered to the soil through the steam sock. The soil should be heated to 180° Fahrenheit (82° Celsius) for 30 minutes to remove harmful pathogens, weed seeds, nematodes, and contaminants. Once the soil has been sterilized and cools, you are ready to plant.
Steam N Air Soil Sterilization Equipment

Once attached to each other, they take on the job of pasteurizing porting soil and other materials. Since these are components, the customer has the option to buy one Steam Generator for one Aeration Blower and Aeration Carts, or whatever combinations are affordable or profitable to the customer’s needs; to the customer may find other uses for the components.
