Compost huggers and regulators;
Most regulations first list 'uses', then list the requirements the
compost must meet for that use.
IMO this does not work because each 'use' (mulch, top dress, soil
application, potting mix, etc) has many different requirements based on
things like; receiving soil, slope, climate, plants, other materials in
the mix ...and many more.
What should be done:
Compost should be put into groups based on test results:
1) High -to- low nutrient provider
2) High -to- low salts (EC)
3) woody -to- high organic -to- medium organic -to- low organic -to-
soil-like
4) Stable -to- unstable
5) High -to- low carbonates
6) High -to- low C/N ratio
7) high -to- low size distribution
8) ......
Let the GROWER, the DOT foreman, the one trained to stabilize a bank or
grow a pine tree; the one who knows what TYPE of material is needed and
HOW MUCH is needed for a specific site make the decisions. They are not
stupid and they know more than the regulators do about what is needed at
a specific site because there are so many on site variables and they get
to look at the site. From experience they know what works. If they want
to keep their job they will do the right thing so they can be TRUSTED.
And let the composters provide them with a wide variety of materials to
work with. In fact let them provide the COMPLETE RANGE of materials in
the list above. The feedstock of each compost facility will determine
the type of material they can provide. And they will formulate for the
best market - but let them sell ALL.
