Everyone better be sure WHAT rye they are talking about...... There is Rye as in(Secale cerale) Then there are the RYE GRASSES which are (Lolium xxxxx) I think that is right. An annual ryegrass WILL NOT over winter, so that would prolly be a good choice. I believe Percy seeds ryegrass with his last application of N on the corn, the ryegrass just sits there, then when the silage is chopped off it takes off..... according to him. Maybe he could provide more info.
I can provide LOTS of information, most of which is useless!! If you say so, that RYEGRASS that we interseed in our corn that would freeze out in your couuntry...I find it to be really winter tuff, it doesn't survive a cold blast in the spring after it comes outta dormancy. 20# of that stuff is waaay toooo much, IMHO, and if your desire is to kill it in the spring, 3# would be unuf for me. This seed is lightweight, so a # is alot of sprouts. Look it up, its just plain ole annual Oregon Ryegrass, the same stuff they interseed Fla.'s golf courses with to keep them green all winter. It doesn't like heat.
The neatest process I saw by movie...was just laying it down flat, then planting, and the rye recommended has a tremendous
root mass which is important with trace elements right on up to the nitrogen break down of the surface material.
All of a sudden 48 is reading the "rules"...not sure about his practicing of said rules until this subject came up
quick question, about bringing CRP into production...and how many total ounces of product that CAN be applied to
kill the grass...by label, and then what to do if there is still something surviving...I've still had better luck with no more
than 18 to 21 oz at a shot.
