So if I understand correctly, we must not use "small grass" mowing waste, therefore of the lawn type (when it is maintained lol).

I understand that it was the lack of air grass clippings which did not allow the use of lawn waste but a mixture hay / grass should not let bad air ...
Is it possible to mix 2 to boot? In what proportion? 1 / 2? 1 / 3?
I could use this "starter" vegetable patch to experiment ... like a 100% hay, 1/3 sod, and a 1/2 strip? And see what it looks like in a few months?
subsidiary question in one of your last video you said that you let grass strips for certain animal species any hay width recommended you 2 between bands turf?
1) Lawn mowing mainly raises the question of "too much nitrogen" / a boost to bacterial mechanisms to the detriment of the rest (bacteria and fungi are always a little antagonistic).
The hay is already balanced and rich in nitrogen. Hence no depressive effect.
Hence useless, even risky, to mix grass (or any very fermentable fresh organic matter).
It is rich in cellulose, which is also suitable for fungi. And that starts the production of humus - sorry, "humic substances".
2) Grass clippings, rich in N (nitrogen), are a good complement to substrates poor in N and too rich in C: sawdust or shavings, straws, coconut fibers, cocoa pods ...
There, by mixing a rich material and a poor material, we manage to restore a balance.
3) This is the complexity of living things: a C / N balance must be respected; cellulose and lignin must be provided to also boost the fungi and initiate the synthesis of humic substances; it must be avoided that it settles; it must not decompose too quickly, otherwise the ground is found bare; it should not decompose in winter otherwise the nitrates go into the water ...
There are no ideal solutions. Only the least bad compromises.
In the intro (provisional) of my book (under construction), I wrote that the way of doing things (a lazy vegetable garden) is simple. The mechanisms behind 'a formidable complexity, at the limit of what I am able to explain and what a forumeur can understand. Basically, it's like driving a car: reduced to changing gears and turning on the turn signals, it's very simple ... If you want to understand what is happening at all times, direct injection, the calculator, the explosion, valves, etc etc ... it gets tougher!
Hay is a good compromise in itself.
The mixture of straw / mowing or sawdust / mowing another ... what I sometimes call a "substitute" for hay.
4) The bandwidths: each to his taste.
I think that below 1,5 m, we "lose" space. It is necessary to maintain the edges a little (the clovers, for example, "invade" the boards ...). You can pick or act from both sides, without stepping on it too much.
For the grass strip, it is the width of the mower with a little margin ... For a maintenance ... lazy!
