I found that fascinating. Looks like from that, my homemade compost is high in N. Thanks LJack.

 

[juniorgrower]

That's some good info! Thanks Jack.

 

[Lemon Jack]

Ya I thought it was pretty useful One question though in a vermicompost bin. Will feeding high N foods translate to N rich castings and so forth. Meaning this list would be equally as usefull for a vermicompost pile???

 

[The Hemp Goddess]

Good info.

One comment on the smokehouse ashes. Never use any ash from charcoal in your compost.

Short answer is, yes.

I assume the long answer wil be a tad more complicated.. . Any articles or anything about the matter you know of?

 

[Wetdog]

I'll look around, but it's basically like computers. Garbage in, garbage out.

I did the N-P-K thing at first, now I don't and just make sure there is good stuff going in.

I do add amendments to the bedding I make. It is peat based + Dolomite, Azomite, Alfalfa meal, soybean meal, kelp meal, coffee grounds. They are fed mostly coffee grounds with handfuls of alfalfa and soy every now and then. We don't generate all that much in the way of food scraps.
