I discussed it, showed the first (potato) video to Wifey and we decided to give it a shot.
In the video, they laid out a grid of chunks (appears to be 2"+ thicknesses) of straw bales to their field in the fall and let the straw rot. In the spring they took the rotted hay, fluffed it up and pulled sections apart in areas and laid out seed potatoes. Once their potatoes were laid out, they covered them up again.
Note: I learned that although the terms are often used interchangeably, there is a difference between hay and straw. Hay is dried field grasses where straw is hay that has had the seed pods largely/entirely removed. Hay is often consumed by animals and straw is bedding.I took a trip to the local Ace hardware and bought 4 small bales of straw. Wifey and I then laid them down in a grid to rot for the remainder of the winter until it gets to be potato planting time.
