Intoxication of even a small amount can result in death.. usually from ingestion, but also from inhalation (while burning), or even skin contact. I found a small stand last year behind a pond on another property that I was caretaking. I had planned to pasture my pigs there, but that idea was abandoned upon discovering poison hemlock. I removed what I could, (completely covered up, and heavy rubber gloves) in an attempt to interrupt the reproductive cycle. The property has since changed owners, but I made sure to make the new owner aware of the danger, and wished him luck!

My thought, too. Is that what real mobbing takes?

I let everything grow and die off naturally now at the advice of a really smart and experienced NRCS agent who has really helped me. I was originally going to roll-crimp the grasses down to create a nice thick mat of biomass. As we were walking over the pasture, the NRCS agent and I were discussing the approach. He said it would be even better if I just let the things grow and die off naturally. I took his advice and am happy I did.
The land holds more water and allows it to infiltrate more slowly. The die off in the winter puts it all onto the soil and it begins decomposing quickly. The earthworm population has exploded ... and I have to assume the microbial live has too. Repeated mowing and haying reduces the species of grasses and forbs in a pasture. By letting the grasses and forbs die off naturally, I have a more extensive root network for longer than if I rolled, mowed or hayed.
Those are my two cents.

If you want a completely different pasture mix, you can plow shallow so it is just turning over sod and not inverting deep soil and then plant new mix.
Key line subsoiling will break up compaction and speed up root growth with minimal impact to microbiology or existing plant mix, but repeated use will limit the fungal network.
And as Dan said, letting it go to maturity and degrade naturally also feeds the soil differently. As does running livestock.
So what do you want for the pasture?

I currently have about 20 acres in pasture that previously was being hayed twice a year before I bought it.

By letting the grasses and forbs die off naturally, I have a more extensive root network for longer than if I rolled, mowed or hayed. Key principles to take away: 1) disturb the soil as little as possible, 2) keep living roots in the soil as long as possible, 3) encourage biodiversity, 4) keep cover on the soil as long as possible.
I would never turn my pasture over. That exposes the soil food web (microbial life) to harsh conditions that kill much of it. It also vaporizes valuable soil moisture. Most of all, it breaks down the soil structure reducing its ability to infiltrate water and you end up with compaction and erosion problems.
Let it grow and die off naturally until you're ready to manage it with managed/mob grazing. You can even inter-plant a row crop into cover crop with a seed drill. Your animals could graze the top third and trample the rest onto the surface of the soil if you move them frequently enough. But, I would never turn my pasture over. That leads to compaction, erosion, and destruction of soil food web and soil structure.
Those are my two cents.
