Thanks for the feedback! I'll do 2 replies, one for the garden and one for the website to keep them separate.
Regarding the garden... I am assuming you have established it for a few years so you aren't trying to kill sod.
Do you tend to plant in rows? Do you have established paths?
I would mix the things you mentioned with the exception of the wood chips and lay that down. To start out, I normally put down 2-5 gallons of biochar per 32 square feet depending on what I have on hand... so for your application on 1000 square that's like 50ish to 200ish gallons evenly spread which is a lot.
It will be good to mix in the biochar in the fall so it charges over winter.
So if you plant into rows/beds, apply your manure/ compost/ biochar mix heavy in the areas you plant so you don't need so much biochar. This is what we do at our church garden, just apply to beds.
If you till, till this in but not deep... 2 inches should be good.
Then woodchips on top, thicker on the paths and thinner on your bed. This will keep in the moisture but not tie up nitrogen while it decomposes.
If you care to, put in some winecap mushroom spawn in the pathways to start breaking down the chips.
In future years, you'll amend the beds with your manure mix, take your aged wood chips from the paths and shovel as mulch on the beds, and add fresh wood chips to the paths.
