I used too plant oats for winter grazing until I cut herd numbers. Now the pastures naturally provide it as long as moisture is adequate. I don't get the Fall grazing I used to get, but with the weather patterns we have endured the last decade, I wasn't getting it anyway.
Neighbor still plants. I think the number he told me is $120 an acre this year, just fertilizer and seed.
I used to rely heavily on farmed forages in order to run the maximum number of cows possible. I'm convinced all I did was provide a good income for everyone I wrote a check to so that I could accomplish that. Didn't seem to keep much for myself.
