How to sample what you compost.

[DirtMechanic]

We often forget that composting is an oxidation process exactly like burning. True higher temps destroy some value but then making a fire is also educational, as the compounds in the fire will show their true colors. Here is a paper bag for containing charcoal aflame upon a stump. Can anyone tell me the reason the flame is burning that particular color?

And...is is good for soil?

Assuming the picture is a fair representation of the flame. Copper compounds give a blue/green colour. Possibly from staples in the bag.

How Does a Flame Test Work?

The flame test is an analytical chemistry method used to help identify numerous metals and metalloids.
