EM-A Active Solution Microferm

Q: Does Microferm EM-A need to be activated before use?

No. Microferm EM-A is a solution that has already been activated through fermentation. Simply dilute it in water, then use it to water or spray. That's the key difference from EM-1, the mother solution, which you have to multiply yourself.That makes Microferm the easiest choice for the garden, compost, pond, or stable. It contains water, cane molasses, and non-genetically modified EM microorganisms, and it comes in Bag-in-Box packs and containers ranging from 0.5 to 264 gallons (2 to 1,000 liters).

Q: How do I use Microferm in the barn or chicken coop?

Dilute Microferm at 34 fl oz (1 L) per 26.4 gallons (100 L) of water and spray it on bedding, stalls, and chicken coops to reduce unpleasant odors. For horse barns, our Vulkamin product page also suggests a stronger 5% dilution, or 1.3 gallons (5 L) per 26.4 gallons (100 L) of water. Spray 51 fl oz (1.5 L) of this solution, which contains 2.5 fl oz (75 ml) of Microferm, 3 times a week, along with Vulkamin powder on damp areas.Microferm is neither a disinfectant nor an animal care product. If you have any questions about your animals' health, please ask your veterinarian.

Q: How long does Microferm last?

In a Bag-in-Box, Microferm keeps for up to 1 year after production: the bag contracts as you use it, which limits contact with air. If it comes in a jug or an IBC tote, use it within the year for best results.Store Microferm away from sunlight and freezing temperatures, with the cap tightly closed. Slight swelling of the container or a little sediment at the bottom is normal for a living culture. The date on the packaging is the manufacturing date.

Microferm EM-A® is a pre-activated solution of Effective Microorganisms (EM®), ready to use after dilution. Produced through a natural fermentation process (no GMOs, no chemical synthesis), it contains a wide variety of beneficial microorganisms (around 80 families) that work together in synergy.

Microferm EM-A - Active Effective Microorganisms Solution

Already active, Microferm steers the breakdown of organic matter toward fermentation rather than putrefaction. It stimulates the colonization of soil, plants, and organic matter (yard waste, food scraps, manure, animal bedding…), speeds up composting, and reduces odors as well as flies.

Approved for use in organic farming, it helps boost soil biological activity and fertility.

Microferm EM-A® is an eco-friendly, versatile solution for gardening, agriculture, livestock, and organic matter management. It turns waste into resources, improves soil quality, and contributes to a healthier, more balanced environment.

Benefits

Efficient transformation of organic matter;
Faster composting and better-quality manure;
Reduced odors (ammonia, sulfides…);
Fewer flies and better air in the stable;
Stimulates soil microbial biodiversity;
Improves soil structure, fertility, and water retention;
100% natural, safe for people and animals;
Optimizes nutrient recycling.

According to the principle of microbial dominance, a regular supply of constructive microorganisms limits the growth of pathogenic germs and promotes a bacteriologically healthy environment.

Composition

Water, cane sugar molasses, Effective Microorganisms (EM®).
Microorganisms collected in nature, specially cultured, not genetically modified.

Uses

Plants and soil
Dilute 1.3 fl oz per gallon of water (1 cl per liter, ≈1%) and water soil, vegetable gardens, lawns, or indoor and outdoor plants regularly.

Compost and manure
1.1 qt (1 L) per 35 cu ft (1 m³) of organic matter, diluted in 2.1 qt (2 L) of water.
Promotes faster composting with fewer unpleasant odors.

Bokashi in the garden
2.1 qt (2 L) of Microferm in 2.6 gal (10 L) of non-chlorinated water per 35 cu ft (1 m³) of organic matter (50–70% dry matter). Pack down and seal airtight. Ferment for 8 to 10 weeks.

Ponds and water features
1.1 qt (1 L) per 264 gal (1,000 L) of water (split into several doses over the year).
Improves the breakdown of organic matter and reduces sludge buildup.

Animals and livestock
Dilute 1.1 qt per 26 gal of water (1 L per 100 L).
Spray on bedding, chicken coops, stalls, and animal coats to neutralize odors.
In the stable: improves manure quality and reduces infection pressure.

Rain barrels
1.1 qt (1 L) per 264 gal (1 m³) of water per year to prevent odors caused by unwanted fermentation.

Septic tanks
1.1 qt (1 L) per 264 gal (1 m³) of septic tank volume.

To ensure a regular supply of EM and maintain biological balance, we also recommend cleaning your toilets with EM Clean. That way, each time you use it, a small amount of EM® naturally reaches the septic tank, helping with continuous, effective maintenance.

Available formats

BIB (Bag-In-Box): optimal protection against air thanks to the collapsible bag. Keeps for up to 1 year after production. Ideal for occasional use over a long period.
Jug / IBC: suited to large volumes and intensive use. Use within the year for best results.

I love this product! Since I started using EM Microferme, my plants have turned into a real jungle! 🌿🌱 The growth is impressive and my plants are thriving.

Plus, I use far less fertiliser, which saves me a nice bit of money. The product is very easy to use, both as a foliar spray and diluted in the watering water for the soil.

Visible results, simple to use and savings to boot! I highly recommend it, I couldn't do without it anymore! 🌿
