How to Sterilize Soil with the Hydrogen Peroxide

Nowadays, we often use Hydrogen Peroxide for cleaning or sterilizing water. Hydrogen Peroxide is also used to sterilize the soil. It’s very convenient and helpful. The below information is very useful for anyone who wants to know how to sterilize soil with the Hydrogen Peroxide to improve the quality of their soil.

Why do we need to sterilize soil?

Sterilizing will improve your soil “health.” So that, you can prevent your soil from any fungal diseases and other problems. In fact, there are several ways to sterilize the soil. They include steaming and heating the soil in the oven or microwave.

  • Steaming: This method uses hot steam to sterilize soil, kill weeds, bacteria, fungi, and viruses. The average temperature of this method is 180 °C.
  • Oven method: Put the moist soil in an oven-safe container and cover it with foil. Then set the temperature somewhere in the range of 100-120 °C and cook for 30 minutes.
  • Microwave method: In this method, you just moisten the soil and put it in a plastic bag. After that, you leave the top of the bag open and place it in the microwave. Cook it for 2-5 minutes. When the temperature reaches 80-95 °C, turn off the microwave.

What is Hydrogen Peroxide?

The chemical formula of Hydrogen Peroxide is H2O2. It’s pure form and colorless liquid. The boiling point of Hydrogen Peroxide is 150.2 °C. In reality, Hydrogen Peroxide undergoes thermal decomposition and is capable of exploding at this temperature. Hydrogen Peroxide melts at -0.43 °C.

Benefits of Hydrogen Peroxide for your soil

Hydrogen Peroxide (H2O2) decomposes into water (H2O) and an oxygen atom (O). This oxygen atom is capable of killing bacteria strongly. After that, the two oxygen atoms will combine each other to form the oxygen that supplies oxygen to the soil.

If Hydrogen Peroxide sterilizes your soil, it can prevent from fungus, bacteria, weeds, and enhances root system of any trees planted on it. This article will provide you step-by-step instruction to sterilize soil as simply as you can.

Sterilizing soil with Hydrogen Peroxide is appropriate for amateur gardeners. It doesn’t require very much about technical knowledge. You can practice at home.

After learning about Hydrogen Peroxide, we move to the most important part of this article.

How to Sterilize Soil with the Hydrogen Peroxide

Just two simple steps to sterilize soil with Hydrogen Peroxide.

  • Step 1: Mix water and a bit of hydrogen peroxide in a bucket: You will need a bucket or a glass to mix Hydrogen Peroxide with water. Your soil needs to be sprayed fully of surround, so you need to have a bucket big enough.

*Note for you: We shouldn’t apply hydrogen peroxide to soil directly. The reason is in high concentration, Hydrogen Peroxide is an aggressive oxidizer and will corrode many materials, including human skin. Therefore, we need to make sure about the percentage of Hydrogen Peroxide and water. In fact, we often use 3% Hydrogen Peroxide or 35% Hydrogen Peroxide to mix into water. The below chart will show you how much peroxide is enough to use.

1 cup 1 and ½ teaspoons 7 to 10 drops
1 quart 2 tablespoons ½ teaspoon
1-gallon ½ cup 2 teaspoons
5 gallons 2 and ½ cups 3 tablespoons plus one  teaspoon
10 gallons 5 cups 6 tablespoons plus two teaspoons
20 gallons 10 cups ¾ cup plus one tablespoon plus one teaspoon
Bathtub (approximately 25 to 35 gallons) 12 to 17 cups 1 to 1.5 cups.
