My hayfield was cut like that for years (20+) without a lot of fertilizer being put back on. Every now and again someone would lime it and maybe put a little fertilizer but rarely. Soil sample I took showed it lack a lot of phosphorus. Like so much I think I would have to fertilize it every year for awhile without cutting any hay to build it back. Lol.
I fertilized it twice a few years back but ever since I had to change hay guys and I am only getting 1/3, I do not fertilize. By all accounts my cows ought to be starving in the winter but they do pretty good on it and I do not supplement. I really don't know what to think about it all…
My field is what we consider bottom land here and our winters are wet so grazing it in the winter would not work well. If I could winter graze it I could probably use it and my pastures and feed very little hay at all. My hay guy is older and will quit at some point soon and I still may fence it and graze it, especially if I could find a reliable source for a little hay.
Buying equipment, fertilizer, etc. does not pencil out here for me. I will likely have to find a way to graze and minimize hay purchased or quit…
