How to Collect a Soil or Compost Sample


It really is that simple, right?

Dig just under the top layer in a few spots, dump into a bag.

While I’m not going with this particular lab, I was doing some comparative research on techniques although there’s not much to it.

I got my cooler packs, my quart-sized ziploc bags and a trowel.

I’m going to take a sample from the middle, but I’m more interested in the materials that are on the outer edges of the pile.

These particular areas are where it’s not as likely that the higher register of thermophilic activity was able to reach.

I’m still not worried, but I’d like to make my test as honest as I can get it.  The stuff from the center of the pile will be thoroughly cooked, so when that comes back looking fine I won’t be surprised.

Have you ever seen someone so excited about soil tests?
