How to Activate EM-1 for the Best Soil Amendment

About the Activation of EM-1®

The use of biological products in agriculture and animal husbandry is crucial for the future of regenerative agriculture. However, it is important to be aware that these products require microorganisms with the ability to:

  1. Survive in the environment where they are applied
  2. Activate or wake up from a dormant state
  3. Multiply or proliferate to achieve the desired effect

Unfortunately, many of the biological products available on the market today are industrialized using chemical mediums and lyophilization (freeze drying). This means that all the cells need to go through these three steps to have any effect when applied.

EM•1® is better than all biological products currently available on the market in the USA as EM•1® is industrialized through natural processes that keep the microbes in their natural state.

EM•1® is even able to bypass those three survival steps above, as well as add an extra, and very powerful benefit to its uses. EM•1® produces metabolites, natural beneficial substances that support life. How? By using a simple process of controlled activation.

EM•1® is a microbial concentrate, and the microorganisms inside are dormant, but in their natural state. This means that waking up these microorganisms is very simple.  Just add 5% molasses plus 5% of EM•1® concentrated solution and 90% water together and mix well.  Let the mixture ferment for 7 days. That is it! After 7 days, the microorganisms will be awake,  bypassing the survival and dormant state, and proliferate in the solution.

During these 7 days of controlled activation, when the exact quantity of molasses (sugar) is used, the microorganisms will fill up the activated solution with metabolites such as amino-acids, organic acids, vitamins, enzymes and antioxidants that support other life forms that can also feed plants and animals. Those substances are “the icing on the cake”.

Over the last 40 years EM Research Organization  (EMRO) has invested heavily world wide in standardizing this activation process so that every user can get the highest performance with the most consistency from EM•1® Technology.

By adding precisely 5% of EM-1® and Molasses and 90% water  and waiting at least 7 days, EM•1® not only reaches its full potential but also becomes 100% free of any possible contamination from other pathogenic microorganisms.  That makes EM•1®  the safest biological product available on the market and as such, it has been granted several distinct certifications, including organic

So, the controlled activation process is important in order to bypass all survival processes of the microorganisms, creating a very powerful natural biochemical barrier against pathogenic microbes, and enriching the solution with powerful amino acids essential to the growth of animals and plants.

All instructions, directions and recommendations of EM•1® microbial solution are standardized on the process of activating EM•1® concentrate at:

  1. 5% Concentrated EM-1® solution
  2. 5% Molasses
  3. 90% Water

The use of EM-1® outside of this recommendation will result in less than optimal performance and is not the responsibility of TeraGanix or its partners. Please check below for further information on how to activate EM•1®  properly.

Use the table below to determine the quantity needed. 


  1. In a clean container, add 1 part (5%) of EM•1®, and 1 part (5%) of pure molasses, mixed in 18 parts (90%) of clean water. Mix well to form a homogeneous solution
  2. Leave to ferment for 7 days.
  3. Activated EM•1® is ready to use from the 7th day, when the pH of the solution is between 3.2-3.6, or when it has a pleasant bittersweet smell and the color changes from dark brown to orange-brown. To use, dilute at the rate of 1:100 or 1 oz per 1 gallon of water. Do not apply AEM® undiluted.


  • Activated EM•1® should ideally be used within 45 days of activation, after that the effectiveness of the microbes starts to drop. It can be applied by spray or through a pre-established irrigation system. It can be diluted to adapt to the application system such as irrigation tanks, spray tankers or backpack pumps, watering cans.
  • For best results, activate in temperatures equal or greater than 62°F. Activations in temperatures below 62°F will take longer than 7 days to activate, and activation (or storage) below 31°F will freeze and kill microbes (including EM•1®).
  • Always store the Activated EM•1® in a cool protected environment to avoid contact with dust and water.
  • EM•1®-Activated is totally biodegradable and compatible with mineral oils, natural fertilizers, foliar fertilizers and biological agents. Commonly used tackifiers and moisturizers can be used.
  • EM•1®-Activated is not compatible with chlorine, copper products, bactericides and fungicides. In case of having to apply a fungicide or insecticide to the crop, it is recommended to wait at least 4 days to reapply EM•1®-Activated.
  • Dosage rates: *Composting of organic waste: 2 liters of EMA per m3 or Ton., when assembling the pile and when the temperature reaches 60°C. Apply this fertilizer directly in the field at a dose of 1 Kg/m². *Soils and substrates: 20 to 40 liters of EMA per ha., 4 to 8 times per year. *Hydroponics: 1 liter of EMA per 2,000 liters of nutrient solution, once a week in the production cycle.
