I congratulate you for the Voluntary Guidelines, a well complete set in fact, and for the opportunity in discussing them in the forum.
Just to add my support to the comment of Timothy Krupnik on "...adding a section on easy to measure and monitor indicators of sustainable soil management that can be implemented by practitioners and including a toolbox of different methods that can be used to maintain and improve soil quality.".
My view is that providing a guide of indicators would greatly help practicioners, framers, consultants, and others on the search for a sustainable managemnt of soils. These should not be set for regulatory purposes.
