Background: (I know this is bit long winded....but I need to set the stage)
Started my no-till journey in August of '21. My first seeding was 100 lbs of rye and 34 lbs of a mix of clovers, brassica and peas. I have four clover varieties of Durana, Alice, Ladino, and medium red clover. I had a pretty good start in fall with frequent rains after drilling into nuked attempts of spring / summer failed crops. Was very satisfied coming into '22 Spring with great rye and clovers and in June I planted GCC Summer Release mix. I got some reward for that into July and August with some sorgum and beans in my now very well established clovers. 8 acres worth.
In late June I used my roller crimper to lay a very nice Matt of rye over all my plots........and watched the clover emerge through the rye. Perfect!
After mid-July I planted some GH Radish, Forage Collards, PT Turnips to get some growth for fall. Not much reward for that effort but now when I get to August I do see a "fair" mix of some of these brassica leaves in my plots. Not great.....but hoping for more. I'm in zone 3 in Northern MN......so In late August it was time to get my winter rye and another mix of clovers and brasica drilled into the now very lush clover plots.
During the summer I did a few applications of (edit) Clethodium where I had grasses and mowed over the top of my clover to control broadleaves. These efforts were timely and seemed to do the trick.
I did mow a few strips to the "nubs" in my August efforts......but otherwise drilled these seeds into the standing lush clover. The areas where I mowed short did a bit better than the un-mowed.....but that clover I mowed came back like gangbusters. The rye planted in late August, has come in well in the 7.5" strips thought my plots and I feel certain I will get a decent stand of rye for weed control and mulch again for fall and into next spring.
Now my concerns and how to fix it?
I should not complain as I have about 8 acres of beautiful clovers that are reasonably weed free and some mixture of brassica forage intermixed through most of my plots. My issue is......that I do not have good brassica stands to attract the deer once that clover diminishes due to the onset of cold weather......which is just now starting here. We getting some nighttime freezes now.......and that clover will be mostly gone come our rifle season.....where I will need to rely on the rye to feed the deer. I don't think I have enough decent brassica to draw and basically no turnip bulbs or radish bulbs.
I suppose it's too late this year to get a great result and I will "limp through" with the clover and rye and meager brassica's I have.....but there is always a better way to do things. So my question for next year becomes: How should I set-back my clover to establish a better brassica result for fall of 2023? Should I do small brassica plots via nuking or mowing areas?.....or what do you guys do??
The pic below may be the best of my brassica in the clovers......not a horrible situation.....I just want to learn how to do better next year. Those pics are now a month old....that sorgum is brown and the clovers are beginning to diminish. Thanks for considered input to my questions above.
