Yeah, I follow that, but how does method of termination alter carbon, nitrogen or their relative ratios? That’s dependent upon the plant and timing, as you mentioned.

It doesn’t. The practical benefits to a crimper are that you are eliminating broad spectrum herbicide (both from a cost perspective and a warm and fuzzies about not using chemicals perspective), and that it mechanically flattens the terminated crop to form cover. Like anything else it’s mainly weighing a high one time cost of a crimper versus a lower but continual cost in herbicide and figuring where it pays off. As said, herbicide and a pass with the drill accomplishes the same, both only working and improving the top 3” of soil the desired crop actually uses, as opposed to trying to amend the entire depth a tiller will turn over.
The other and most controversial difference between crimping vs kill then drill is the perceived effect broad spectrum herbicide has on soil micro and macro biology. I’m no expert so I’m not wading into that bullshite, but count me as a skeptic. I personally use herbicide and inoculate all legumes/clovers prior to planting.

Going from the tillering stage to flowering, the carbon-to-nitrogen ratio might change from 18:1, where it is going to mineralize nitrogen as it decomposes, to 50:1, where it is going to immobilize a lot of nitrogen as it decomposes. That’s not necessarily a bad thing. A lot of nitrogen that could have leached out of the soil is being retained and will be released to the crop as the season progresses. It does mean that nitrogen needs to be managed differently, though

Or are you talking about crimping vs mowing or spraying?
Edit: I thought you were asking about timing.
Another benefit is that you can mount a crimper on the front of your tractor to crimp and plant in one pass.
When you spray to terminate crops they may stay standing for a long time before they even fall. Especially grasses that we use a lot in fall mixes. You could kill it then mow it after it does, but then you will have windrows through the field and now you have made a total of at least 3 passes across the field. (Spray, mow, plant)
Just mowing it may not kill it and the mowed crop could out compete the planted crop.
A crimper won’t kill everything in the field either. If you do it when grasses are too young they will stand back up.

I’m not sure the method of termination has an impact on what deteriorates into soil (though chemical sprays cost and do change pH I believe). I want to try a crimper to break the stems on my cereal rye so it won’t stand back up - I want it to lay flat and smother weeds.
I’ve done 2 fall/winter crops and neither was crimped, neither suppressed weeds good enough in the subsequent spring/summer. But, there were other factors - like neighbor’s cows that thinned out my crop.
I’m not saying what I’m doing is the only way or the best way, but I am seeing changes I like in my soil and in the deer herd, I believe. Time will tell. But I rent a Truax drill, I have bought local and Green Cover Seeds and prefer the latter, and I’ve sprayed herbicide twice (hired it sprayed). Lots of variables, it might take a long time to figure it all out.
I’m having a hard time justifying buying A $12k implement to use 2 days a year. But, I might get there. For now I’ll rent and borrow if I can. But I sure do want to try a crimper.
