How Do You Activate EM-1?Updated 6 months ago

Activating EM-1 (Effective Microorganisms-1) is a process of expanding it to increase the volume and make it more economical for use. Here’s a step-by-step guide on how to activate EM-1:

Equipment and Ingredients

  • Clean Container: Use a container large enough to hold the final volume of activated EM-1.

  • EM-1: Original EM-1 concentrate.

  • Molasses: As a carbohydrate source to feed the microorganisms.

  • Water: Chlorine-free water, as chlorine can kill the beneficial microbes.

Activation Process

  • Proportions: The typical ratio for activation is 1 part EM-1, 1 part molasses, and 20 parts water. 

  • For example: To make 22 liters of activated EM-1, mix 1 liter of EM-1, 1 liter of molasses, and 20 liters of water.

Mixing:

  • Dissolve Molasses: First, dissolve the molasses in a portion of the water. Warm water can help to dissolve the molasses more easily.

  • Add EM-1: Once the molasses is fully dissolved, add the EM-1 concentrate to the mixture.

  • Add Remaining Water: Finally, add the rest of the water and stir well.

Fermentation:

  • Cover Container: Cover the container loosely to allow gases to escape during fermentation but prevent contaminants from entering.

  • Fermentation Period: Allow the mixture to ferment for about 7 days. Keep the container at a room temperature between 20°C to 30°C (68°F to 86°F) for optimal fermentation. Lower temperatures can slow down the process.

Monitor Fermentation:

  • Check pH: The pH of the activated EM-1 should drop below 3.6, indicating successful fermentation.

  • Smell: It should have a sweet-sour, yeasty smell.

Storage:

  • Store Properly: Once activated, store the EM-1 in a cool, dark place. Use an airtight container if you’re not planning to use it immediately.

Usage:

Use activated EM-1 within 45 days for best results.

Important Notes

  • Water Quality: Ensure that the water is free from chlorine and other contaminants.

  • Container Material: Use a container made of materials that do not react with EM-1, such as plastic or glass.

  • Avoid Metal: Do not use metal containers or utensils as they can react with the acidic environment of EM-1.

  • Aeration: During fermentation, the mixture should not be airtight as the microbial activity produces gases that need to escape.


Activating EM-1 is a cost-effective way to extend the product for larger applications, especially in agricultural settings. Always ensure to follow the correct proportions and conditions for effective activation.
