Chuck, your post caught me by surprise.
I've found that bokashi and biochar (B&B) have had absolutely and undeniably wonderful effects on the garden. We went from average production to over-the-top give-it-away-before-it-rots (and take-some-out-of-the-back-of-the-truck-because-it's-making-the-wheels-rub-the-fenders) production after introducing the B&B.
But I did my research first, and found that I should combine the bokashi (which in my case is mere kitchen scraps) with the biochar ASAP and then age.
So, in my 55-gallon bokashi lidded barrel I make layers of char and bokashi. Sort of like a nasty lasagna. At the end of a full year (in the fall for us), all I have is a visibly dry* charcoal product to shovel into the garden. By combining the B&B together, I am causing the char to "pre-charge" with nutrients, same as soaking char in a barrel of pee.
When we started putting this into the garden we got not only a much better yield, we also got healthier plants that were disease-resistant and insect resistant. Insect damage dropped to near zero, and mold/mildew/blights disappeared altogether. In previous years, I've grown about 1000 sq. ft. of wimpy and diseased corn stalks. These past two years with the B&B, I have grown bountiful, delicious, bug-free corn.
But all this soil fertility is assisting the weeds and grasses, too. This is why I call it an "extreme grass attack".
I've both blessed and cursed myself. I'm currently thinking of not having a garden at all next years so I can solarize for the entire season. I guess I'd till in this year's bokashi in the fall and then seal it all off with plastic until 2016.
Thoughts?

*By visibly dry, I mean it looks dry. If I put a piece of the charcoal on a paper towel, a lot of moisture wicks into the towel.
