Couple questions about the release process (food plots)

I’m looking at doing food plots this year and getting into some kind of system. All in all it will be about 10-12 acres.

I’ve been tilling, broadcasting, and Culti packing for years. I’ve recently been looking into the release process. However, one part doesn’t make sense to me….

If crimping lays down the old growth to make a mat that provides mulch, and protects against weeds then how does the sun get to the seeds you want to grow? Wouldn’t the same mulch that blocks the sun from weeds also block it from the planted seeds?

Trying to wrap my head around what I want to do. The release process sounds great in that it would save time and get away from fertilizer and herbacides. I’m just wanting to figure it out before making that kind of investment. Would appreciate any and all input. Tia
