EM (Effective MicroOrganisms)

Effective MicroOrganisms (EM) refers to commercially produced cultures of “positive” bacteria. The theory behind how EM works is at the center of bio-active (natural) farming. Found at work in healthy soils throughout nature, EM is a collection of bacterial cultures which can be used to prime the soil in your farm as a way to support healthy plant growth. It can be added to compost piles to expedite decomposition processes as well.  It is a highly cost-effective purchase for your farm also, since it’s price is small, but can be reproduced by following the recipe provided below.  EM can be purchased at most farm and garden shops.  Disclaimer: this is a recipe for EM propogation, not genesis.

EM Recipe

  • 3 Tbsp Molasses
  • 1 Tbsp EM
  • 1 Liter Water

Directions

Place ingredients in a 1 Liter (or larger) sealable bottle (water and soda bottles work great). Close the bottle tightly with the cap and  give your mixture a good shake. After this, loosen the cap to allow for carbon dioxide build up to be released.  The EM will be ready for use in about 2 weeks.  For application to crops, dilute your product in water to a ratio of 1:100.  This can be applied to the soil as a nutritive supplement or directly to the leaves as a means of fighting off infections.  Use the same ratios if adding to compost piles.

Note 1: Once your EM has been brewed, you can use it to make more batches as a way to cut costs on your farm.
Note 2: EM should not be confused with LAB (Lactic Acid Bacteria) cultures or IMO (Indigenous Microorganisms).  EM is a product that is commercially produced while LAB and IMO can be produced at home or on the farm.  We are endorsing EM because of the relative ease of use and access it offers, but we see great value in these other two products as well.
