Nothing special 7mm.Oats in some,wheat in others.I do sprinkle in turnip seed as I'm sowing the grain.I fertilize heavy,because the turnips pull a lot of nutrients from the ground.My plots double as cattle grazing after the season is over.I don't turn the cows into them until the 1st weekend in January.That's when we start having our hardest part of the Winter and deer season ends then.Each plot will have a corn feeder on the edge of it or close to the field that I'll feed about 2 tons of corn, out of 6 feeders,over the season.I also put out mineral blocks too.You have to do better than what your neighbors are doing in my country.There is a lot of hunting pressure.I have come to realize that sanctuary plots are better than food plots I think.Good size places where I won't set foot on especially before,and during the season.
