Below is a post I made about my attempt at throw, spray, and roll of some brassica's. Here's a pic of the plot taken on Monday. For whatever reason it was a complete failure.
In a couple of spots I had a few brassica's sprout, but not very many and not very big IMO for a month of growth and the plot had darn good moisture in that time.
So, in an effort to salvage the effort, I lightly disked the plot, broadcast 70# of rye, 2.5# DER, 25# forage oats, 6# of clover mixes, and about 2# of a mix I had left over. I cultipacked after spreading the grains and again after the spreading the clover.
I worked on 3 other, smaller plots this weekend as well. One I had planted buckwheat in and on that one I spread WR and packed it. The other two had been tilled and soybeans broadcast on them. I didn't make it down to spray this spring/summer so they were chock full of weeds. Mostly golden rod, poke salat, ragweed, wild carrot and ironweed that were well over 5' tall in most places. Interestingly enough there was little to no grass in those plots, but was a decent amount of clover underneath. I was able to spread the winter rye as I dozed my way through the weeds with the UTV hauling the spreader. Suprisingly, upon checking the ground a good amount of seed was hitting the dirt. On one plot I made a round with the handheld spreader around the outside with the rye then cultipacked that path. I would then make another pass alongside the standing weeds with the spreader and spreading seed into the standing stuff, then another pass with the 'packer. I then went over all 3 plots with the sprayer and hit it with a dose of glyphosate. I'm hoping that WR is as durable and easy to grow as I have read. The thatch isn't all that thick and I think those big broad leaves on those will break down pretty quickly. So, for now I'm just keeping my fingers crossed to see if I can get anything to happen...
