This is a continuation / amendment of a thread I started a week or two back. I hope this is in keeping with permies culture / conventions?
Things have evolved a bit since I started the last thread, so the newer summary is:
We need to create long, narrow tracks to keep our horses healthy. For the sake of discussion, let's say we're gonna create two, side by side tracks, each about 20 feet wide and 1000 feet long. So on the order of an acre total.
(As a recap, these long tracks are now seen as the best way to use an acre of land for horses. Much better than anything like a 210 x 210 foot square acre)
The current thinking is that these tracks should have nothing growing on them! So here's the challenge:
I'm trying to really embrace the permie worldview. So I'm not thrilled with creating an acre of bare dirt

Seems like I'll ultimately be destroying a lot of topsoil and so on?
One reason for the no-growth advice is that Spring grass can be dangerous for horses, I know, very weird. (And in fact, two of our horses are in distress because of too much sweet Spring grass

)
If humans could discover which plants might both protect the dirt, AND not get eaten by horses, we could build a better world for humans and horses. (As an aside, my wife creates popular, super-horse-friendly horse training videos. She has thousands of students and followers. So if we can cook up a solution, it could have a BIG impact around the world!)
Any thoughts, questions, brainstorming would be awesome!
