KNF preparation for wood chips

I just had bunch of felled tree mulched on about an acre or two  of my farm.  It was spread out when they finished their work. This area will be a future area for an orchard of native species like chestnut, mulberry, persimmon ans paw paw.  The question is what KNF/ biodynamic preparation would you spray on this area to encourage proper decomposition and providing the best foundation for the new orchard.  Thanks for you input.

Hi John. I'm no expert (mostly working with living floors for chickens) but I'd do a mix of IMO and a top dress of whatever local edible mycelium (fruits and sub-surface fibres) are in your area. I treated an area with IMO and bolete and ran chickens through it. Even with our very short Summers here in the North, I've started to build some soil.

For BD they generally recommend either the 500 which is the horn manure or the more 'modern' pfeiffer field prep spray, which I think is the 500 plus all the compost preps in one. But pretty much any positive biologicals you can introduce will help get the ball rolling. Living roots as soon as possible is also always a good call in my book
