Stoneman, I'd plant both. Plant the soybeans now if you can. Come fall, mow and disc strips in the soybeans and plant those strips in fall food plot mix, while leaving some of the beans standing. I like the idea of giving deer a reason to use that plot 12 months a year. I've never understood why some folks grow summer plots and then till them all under to plant fall mix. They're forcing the deer to look elsewhere for a month or more while the new food plots sprout.

When the beans finally die, you can top sow small seeds like clover where the beans were left standing.
