I'm getting my stuff organized for my first real food plot.I'm planting about 3/4 of an acre in dwarf essex rape,turnips, and austrian winter peas.It looks like I need 13-13-13 fertilizer,but all I can find locally is 12-12-12, which sounds close enough to me.Is that a big deal or will it be fine to use.Forgive my ignorance,but I'm kinda learning as I go.Thanks for any feedback.
