If your intention is to have a ryegrass pasture for grazing and in December and January you can see every place a cow did her duty because it is 10 inches tall, dark green and thriving while the rest of the pasture is 4 inches tall and just sitting their. You would have benefited if your would have fertilized it in the fall. Waiting till spring wastes a lot of grazing time. But if you don't want it for grazing before March or April, waiting till later is not a problem. What is highly evident at this time, fertilizer doesn't work if you don't put it out, it won't work if you do put it out and it doesn't rain. If you do have the "golden touch", put it out at the right time, get the rains on que, it is no longer inexpensive to do so.[/quote]
In some areas of the country Rye Grass (annual) will not produce much until early Spring because it is too warm in early fall, so putting N out in the Fall is bad business since N will leach readily and any N application has a useful period not more than 70 days
Also make sure we are all talking about the same thing i.e. Annual RyeGrass vs Perennial ryegrass
