If you fed the worms a broader array of raw materials (even char) then the resulting vermicompost will be amazing. Exactly as you said it's got a lot to do with what the worms have been fed. That's my goal for next year is to make really excellent bioactive (free) vermicompost. Feed them Bokashi that I make for free, as the worms literally will go wild in the Bokashi. The worms are after all that bacteria. There are guys that use a great deal of vermicompost (castings) in their soil, but most balance the EWC with the raw amendments. There are thousands of N sources, so many ways to get to the same place.Something's been nagging me about EWC. If it's such a perfect fertilizer, why do we need all this other stuff bone meal, fish bone meal, kelp meal, guano, etc, etc? So couldn't one make a mix with just EWC and no other ferts? And vice versa, couldn't someone make a mix with no EWC and just the other ferts? Just wondering, I'm putting together a mix from scratch so might as well get to the bottom of things, no? Another question about EWC, wouldn't the nutrient quality depend on what the worms were fed? If all I fed my worms was banana peels, then it's not exactly a balanced fertilizer, is it. I recall reading somewhere very recently that someone adds EWC for microbes (i.e. only for the microbes). Can't remember where I read it, been reading too damn much lately and that would be defeated since apparently EWC are sprayed/sterilized.
I just went to order a bag of this. I couldn't find an address to see where in Michigan they are.Here is a Michigan based place to get biochar http://michiganbiochar.com/products/
If that is the case, then I'm almost inclining towards not using EWC at all. I don't have any MJ-optimized EWC, wouldn't it make more sense to just use the bone/blood/guano/etc? Which are all known NPK ratios so you can mix 'em up and give your plants exactly what they need? Let it cook down while the microbes do their thing, and off to the races? Not arguin', just askin'.If you fed the worms a broader array of raw materials (even char) then the resulting vermicompost will be amazing.

Tried downloading this twice. Both times it said the file was damaged and could not be repaired.Here is a link to a pdf of Teaming With Microbes for people who dont have it.

Thanks for the explanation - so how does spraying/sterilization alter this?Any grow is improved with EWC. This shouldn't be an either / or. Diversity is always a benefit so use whatever EWC you have as well as the amendments. That's what is generally done. There is MUCH less NPK calculation when building a soil that will use microbes to do the work.
Look at it this way. Let's say your soil is a warehouse. Let's say the NPK in the warehouse is locked away. The microbes are the warehouse workers and they regulate the flow of NPK out of the warehouse (to the plant). Let's say you ordered up too much P into your warehouse. Doesn't matter since it's locked up and the workers will still remove material from the warehouse at the rate they want to remove it.
To continue with this analogy, the plant itself creates the purchase order to tell the microbes what to remove from the warehouse. The Compost, EWC and clay all lock up cations for us. They cations are not available for the plant when locked up.
If we had medium just filled with free-flowing raw nutrients then you would have to carefully balance the NPK. But that's not what we're doing. The soil and microbes gives us huge margin here.
If I have a chance, I will get the names of the makers of the EWC available around here and give them a call. Find out whether they are sprayed/sterilized. Maybe find out what they feed the worms at the same timeDoesn't alter the nutrients available to build the soil. It would simply mean you need to incorporate microbes from local soil, Lacto-B, etc.
The jury is out about the EWC sterilization. This might be a state-specific thing, or an interstate thing. Could be some, none or all EWC is treated. I tend to think some.
