I have noticed that in one of my hay/seed fields, volunteer Timothy has been coming back. There was timothy in that field 60 years ago. I would guess it has come back to be around 10% timothy in that field.
This came from pasture managment manual from the U of MO Extension. I would think that most all of the states would have something similar avaioable from the extension service.
None of these pastures have every had Timothy actually planted in them. But there have been horses on them at various times. Timothy being a prefered horse hay I would eimagine that's where the stuff came from that I have. It's kind of interesting that we had some stands that seeded in may and we have some that are just now seeding. I always just figured timothy was timothy, but there are a lot of differetn cultivars that have significantly different growth patterns. All of the OG seeded within a month or so, same with the fescue.
I had origianlly just pulled those pages from the booklet and threw the rest of it away. I had assumed from the place I picked it up, the extension office, that they were the publishers. Turns out I was wrong, what a shocker that is! It's put out by USDA NRCS and is titled "Missouri soil & health guide for the Ozarks"
