Pathogens are microorganisms, such as viruses or a fungus, that can cause disease. In human beings, they attack the immune system and lead to infection. Battling pathogens in the body can be done with the help of antibiotics and good diet. But pathogens can sometimes be found in soil, where they contaminate the soil and make for less than favorable growing conditions. Heat is one way to rid the soil of pathogens.
Step 1
Sweep the soil of any large pieces of rock or plants, roots, etc. Add any compost and fertilizers to the soil and mix well.
Step 2
Place the soil in a baking or roasting pan. A standard pan can be used, but make sure it has been thoroughly cleaned. The soil should be spread evenly and not be more than 4 inches deep. Cover the pan opening with aluminum foil.
Step 3
Set the oven between 180 and 200 degrees F. and place the pan into the oven's center. Allow the soil to reach a temperature of 180 degrees and remain at this temperature for 30 minutes. Check the temperature of soil with a soil thermometer during baking. If the temperature seems to be rising rapidly and shows signs of surpassing 200 degrees, turn the heat on the oven down slightly and continue taking measurements until the soils heat level is maintained at 180 for half an hour.
Step 4
Remove the pan from the oven after 30 minutes of baking at 180 to 200 degrees. Set the pan on the counter or stove to cool down. Do not remove the foil until the soil is ready for use.
