Is Bokashi Tea (Bokashi Leachate) a Good Fertilizer?

Despite its name, Bokashi composting is a fermentation process for handling kitchen scraps right in the home. It is fairly easy to do and produces few odors. The majority of the material ends up as fermented kitchen scraps and some is drained out the bottom as a brown liquid, commonly called Bokashi tea or Bokashi leachate. Advocates of this process claim that the Bokashi tea is a good fertilizer, full of all the nutrients your plants need.

In my previous discussion about Bokashi, I speculated that the tea contained few nutrients. At the time I found no chemical analysis of Bokashi tea, not even from proponents of the process. One of my readers has now found such a study and I will have a close look at the data in this post.
