Just wondering if anyone knows how to test N-P-K values of compost and/or worm castings. Going to start vermicomposting but would like to know what I’m adding

google it ...
So from what I’ve found. NPK ratios only measure what’s instantly available. The worm castings/compost will have all the macro and micronutrients in slow release form.

So the answer is, the nutrients DONT go anywhere...

Thanks for the help, people
