What is the Difference Between EM-1 and Bokashi?Updated 6 months ago

EM-1 (Effective Microorganisms-1) and Bokashi are both related to the concept of using beneficial microbes, but they serve different purposes and are used in different ways:


Nature: EM-1 is a liquid microbial inoculant, a concentrated solution that contains a specific blend of beneficial microorganisms. These typically include lactic acid bacteria, yeast, and phototrophic bacteria.

Purpose: EM-1 is designed to improve soil health and plant growth. It enhances the microbial activity in the soil, which in turn improves nutrient cycling and soil structure. It’s also used in composting, water purification, and animal husbandry.

Application: EM-1 is diluted with water and can be applied directly to soil, compost piles, or as a foliar spray. It can also be used in aquatic environments and for household cleaning purposes.

Activation: EM-1 can be used directly from the bottle or can be activated (expanded) by fermenting it with a carbohydrate source (like molasses) and water, which increases its volume and makes it more cost-effective.


Nature: Bokashi is a method of composting organic waste using a specific set of microorganisms. It usually comes in the form of bran (or another carrier material) that has been inoculated with these beneficial microbes.

Purpose: The primary use of Bokashi is for composting kitchen scraps and other organic waste. It works through anaerobic fermentation, which efficiently breaks down the waste material without producing foul odors.

Application: Bokashi is typically added to kitchen waste in a Bokashi bin. The process is anaerobic, so the bin is kept sealed. After the waste is fermented, it can be buried in the garden or added to a traditional compost pile to complete the decomposition process.

EM-1 and Bokashi: Sometimes, EM-1 is used to inoculate the bran or other materials to create Bokashi. Thus, EM-1 can be a component in the Bokashi composting process.

In summary, EM-1 is a liquid microbial inoculant used for a variety of purposes, including soil enhancement and composting, while Bokashi is a method of composting organic waste using a fermenting process with microbes. EM-1 can be used to create Bokashi, but they are not the same product and are used in different ways.
