Glyphosate is a non selective herbicide. It will kill all weeds and grasses. Saying that, some weeds and grasses are hardier and require a second application but not many. It won't kill woody plants. You normally spray when the weeds are young and actively growing. Don't disc after spraying, allow the glyphosate to burn down the weeds and grasses. I spray our plots in mid May, here in Eastern NC, which has some of the same weather as Northern Kentucky. This spraying will normally kill everything for 3 to 4 months. I don't disc until I plant (disking causes weed seeds in the soil to germinate and start growing) so hold off until you are ready to plant. Brassicas require 60 to 90 days to fully mature, so check your average first frost date of the fall and count back 90 days and plant. Clover needs a couple of months of cool temps before your first frost to germinate and put on some root growth so 30 to 45 days will be good. Add a cover crop of Winter wheat or Winter rye with the clover and you'll have a great food plot through the fall and winter and the clover will take over in spring. Clover and brassica seed is very small, so make sure you don't plant it deep. The best way is disc well, pack the soil down with a cultipacker, atv or tractor tires, sow the seed and pack again. Good luck and keep the questions coming.
