Red clover is a biannual or shot lived perennial clover and is usually planted in the spring but can be fall planted... Crimson clover is winter annual, planted in the fall and matures by late spring. I would bet, if the forester wants you to make a fall planting for soil building purposes, it is crimson clover you want, not red clover.

I buy a lot of my food plot seeds here: crimson clover

Crimson clover tolerates poor soil conditions and is very hardy! Plus it's cheap compared to most other clovers. If the soil is lowland and is usually a bit on the wet side, I'd plant alsike clover.
