foliar feeding

The term, "bokashi spray," is used to contrast with "bokashi sprinkle." Both terms are used in regards to fermenting food waste, that is, as fermentation starters to make bokashi food waste. The bokashi sprinkle is bokashi bran, a granular solid material, and therefore, is sprinkled onto food waste. The bokashi spray is Activated EM, a liquid, and therefore, is sprayed onto food waste. 

Fermented plant extract formulas and uses vary greatly. These are liquid products. They are similar to tinctures but without the alcohol. Much like bokashi, they, too, are fermented organic matter. A microbial starter, some type of sugar, some type of plant material, and water are mixed into an anaerobic container and allowed to ferment. These fermented materials have bioactive compounds in them and are non-alcoholic. The materials used could include any part of a plant, branches, fruit, or leaves.

Activated EM (also bokashi spray; bokashi microbes; Activated EM•1): a type of bokashi ferment, a microbial inoculant, a soil probiotic, a biostimulant, and a fermentation starter.
