Many native weeds and grasses don't come back until the spring because they need 30+ days of cold, freezing weather to open the seed coating. This process is called destratification, to allow them to germinate. Many annual and perennial weeds, grasses (especially native warm season grasses) require this process.
As far as any food plot "soft" seeds go with grains, legumes like clover, etc.. They will all germinate immediately with the right seed/soil temperature and moisture. Some clovers do make "hard seed" but by far and large most food plot seeds and blends will germinate immediately with the warm temperature + moisture combination.
My question would be why wait to allow germination later in the spring? With fall germination, your plots will have a head start on the weed competition, therefore suppressing weeds MUCH better than a spring planting. Established plant beats the seed on the surface every time..
That specific mix - Loggers Trail - Has quite a bit of fescue and annual ryegrass in it. Fescue is good for ground cover and erosion prevention, that's about it. It holds no wildlife value from either a cover or forage standpoint. It's actually quite detrimental to small animals like turkey poults due to it's sod formation, which limits their mobility.
IF I were establishing a clover plot on a logging road, my first choice would be fall seeding with a nurse crop, especially for perennial clovers. They just take a while to establish due to root structure priority over top growth (like most perennials).
My mix would look something like this (Rates per acre, you may have to walk or use OnX to measure your approximate area) :
- Cereal Rye (not ryegrass!) - 60# / acre
- Perennial White Clover - 6#-8# / acre (Good options include - Ladino, Durana, Alice, Will, White Dutch, etc..)
Depending on sunlight, the rye may get 4'+ high and start to produce heads. You don't have to wait that long but you could mow around May 1 and again a few weeks later to take care of the rye. This will prevent seed set and you'll be left with a nice stand of clover.
Good luck!
