My city offers a composted biosolid from the wastewater treatment plant for $10/yd. I'm going to be doing a 20'x20' keyhole hugel bed. Would this be something that would be good to mix in?
From the website:

We also reclaim the solids which are composted and sold to the public as the Class A biosolids product known as Stonepile Soil Amendments.
The Stonepile Soil Amendments are available for purchase $10 per cubic yard for Biosolids, and $15 per cubic yard for Yard Waste compost.
