The Bokashi activator / starter / booster is essential for getting started and speeding up the fermentation of organic matter while effectively controlling odors. It turns food scraps into compost quickly and cleanly through a natural maceration process in a bokashi bucket or a composter.

Bokashi EM-1 compost activator

This 2.2 lb (1 kg) bag of Bokashi activator is made with EM-1 microorganisms®, known for their effectiveness. These beneficial bacteria trigger the fermentation of food waste by helping it dehydrate, with no rotting and no foul odors. It is the very first Bokashi activator made in France, produced by Moutta Farm from carefully selected local raw materials: the wheat bran comes from the Gers (32) and the molasses from Béarn.

Official EM-1 from Professor Teruo Higa

We use only official EM-1® developed by Professor Teruo Higa, the pioneer and inventor of Bokashi, to guarantee optimal, natural, and well-controlled fermentation.

EM-1 microorganisms

A little goes a long way: 4.4 lb (2 kg) of activator is enough for a two-person household for about a year, making it a cost-effective and sustainable solution.

Use and dosage

It is simple and easy for anyone to use. Just sprinkle a thin layer of about 1.4 fl oz (40 ml), or 4 tablespoons (or two scoops with the 20 ml spoon), directly over all the organic waste in your composter. For best results, add a little activator at the end of each day of use.

Beyond Bokashi, this activator offers many benefits for the soil. It improves soil fertility, rebalances microbial activity, and brings depleted soils back to life.

It can also be used in an outdoor composter to boost decomposition and reduce bad odors, or sprinkled on the surface of pots and planters to stimulate microbial life in the potting soil.

To keep it fully effective, store the activator at room temperature, away from light and moisture. After each use, squeeze the air out of the bag and reseal it as tightly as possible. Its eco-friendly resealable kraft zip bag keeps it fresh for a long time.

Your questions about the Bokashi Activator

The farm's answers to the questions our customers ask us most often.

Our Bokashi activator is made right here on the farm from three ingredients:

Dry and ready to sprinkle, our Bokashi Activator kick-starts the fermentation of food scraps and helps keep unpleasant odors down. It works with all bokashi buckets and for outdoor composting.

On average, 4.4 lb (2 kg) is enough for a two-person household for a year, which means a 2.2 lb (1 kg) bag of Bokashi Activator lasts about 6 months. How quickly you use it depends on how many food scraps you produce.

The activator comes in 2.2 lb (1 kg) bags, sold individually or in packs of 2 or 3 bags, so a pack of 2 covers a full year for two people.

You need to add Bokashi Activator with each new addition: that's what keeps the fermentation going. Work in layers, like a lasagna: a layer of food scraps no more than 0.8 in (2 cm) thick, a thin, evenly spread layer of activator, then press down to push out the air.

Dose per addition: 1.4 fl oz (40 ml) per addition, our product sheets differ]. Add your food scraps as you go rather than saving them up to put them all in at once.

Bokashi Activator has a shelf life of 2 years. The date printed on the pouch is its manufacturing date, not an expiration date.

To keep it fully effective, store it at room temperature, away from light and moisture, and squeeze the air out of the kraft pouch before sealing the zipper. Our tip: keep a week's supply in a small airtight jar.

Yes. In addition to the bokashi bucket and the garden composter, our Bokashi Activator can be sprinkled on the surface of your pots and planters to boost microbial life in the potting soil.

That way, one bag serves your whole home: the kitchen with your bokashi, the garden with your composter, and the balcony with your plants. Be sure to reseal the zip-top kraft pouch tightly after each use so it stays effective down to the last bit.

Yes. In an outdoor composter, whether it's a tumbler or a wooden bin, Bokashi Activator jump-starts decomposition and helps limit unpleasant odors. Use 2 spoonfuls of 0.7 fl oz (20 ml) each time you add a large batch, starting with the very first scraps.

Keep in mind that it doesn't replace dry material. Stick to roughly 1/3 green material to 2/3 brown material (cut-up cardboard, dry leaves). That's the key to a compost with good structure that doesn't turn into a soggy mess.

The product is very, very good and effective.
One small downside: 2 of the 6 bags received had holes in them (with no external damage to the package received).

Nothing to complain about, fast and efficient, good description of the item, reasonable price, only good things. I think my earthworms and other animals owe you a thank you for the quality of the food made with your product, so I'm saying thank you on their behalf, and on my own behalf too, since I'm the one who's going to eat the vegetables.
