Thanks, interesting. Sorry can't help with the farming part of your request (i.e. not a farmer).

Probably everyone who watches will draw different lessons. The thing I noticed was that 'aged' wood chip mulch tilled in later seemed to provide good growing conditions (likely because any so-called nitrogen tie-up eliminated after a season or so of aging?).

I read some recently about how California changes to prevent use of almond shells and hulls as a biofuel for electricity generation had potential to send enormous amounts of these to landfill; can't help but wonder whether unused bits could be used for soil amendment along with wood chips and similar. I see there's lots of research on all kinds of uses, but really hope they're not going to landfill.

Many don't have time to watch a twenty two minute video log, and would appreciate a one-minute written summary. I watched up to the seven minute mark, and what I came away with was that rows with different amounts of wood chips, some eucalyptus, and some with added fertilizer, showed NO significant productivity differences for broccoli. That's a little surprising for a bed that started out with a very low organic percentage. If I understand correctly, that means that wood chips dug in neither helped nor hurt, and in particular that euc chips are not obviously allelopathic. That's my fifteen second summary. A more complete summary assessment would be appreciated.

I did not watch the video. However I do get aged horse manure for my vegetable garden from a horse stable for years. All the horse farms around here used to use straw for bedding now they use wood chips.

I pick up 3 year aged manure from this place and find it really helps to break up my heavy clay soil. I use it primarily for the organic matter not so much for a nitrogen source.

I have found that years ago, 3 year aged manure containing straw was not an issue but now 3 year aged manure that had wood chips mixed in is not fully decomposed. Every time I use it in the garden I have to really pour on the nirogen heavily or my plants turn a bit yellow. Based on this experience i would not want to be tilling wood chips into my vegetable beds unless I did not plan on growing anything for a few years. I do not think it is a good idea.

We use wood chips at the nursery I work at to heel in ball and burlapped plants. Eventually the wood chips decompose to a fine black mush and we remove it from the areas we store BB plants in. It takes about 4 years for them to be fully decomposed. I suppose if one added nittrogen to them, perhaps the bacteria would break them down more quickly?
