Spraying keeps the weeds in control. Rye germinates very easily. Wheat and oats not as much. If you wants brassica to coexist, self reseeding may be difficult. Rye works great, but can choke out other stuff. Wheat might be a better choice if you want other crops to coexist year after year. Spring planted hairy vetch is something to look at. Winter peas is another good fall. Green cover sells about anything you can grow.
Looking back might be better than looking forward. Pre tractor days of maintaining hay fields.
Also, bang for buck and time, shrubs. Willows dogwoods crabapples.
A coworker only does fallow. Only mows once or twice a year. Every few years discs it up as soon as its dry enough in the spring. Deer gobble up what's in there. Try a spot.
Spraying can also encourage problematic weeds. I'm not saying we should never spray, but we should spray in a very targeted way. When weed competition is not a significant problem, we should avoid it. Keep in mind that what are "weeds" for farmers (anything they didn't plant) can be very advantageous for food plotters. Spray strategically.
As for WR, I have never seen it choke out other stuff in a fall plant. I use 80-100 lbs/ac of WR in my mixes. You would really need a very high rate for it to be a problem. Brassica, on the other hand can become a problem for other crops in the mix if the rate is too heavy. These rates should not exceed 2-3 lbs/ac depending on the specific brassica. WR ca be an issue the following spring if your fall plant is covering spring, but it is easily controlled with a mower. This keeps it alive and working against many summer weeds while making it non-problematic for companion crops in the spring.
