frost seeding
n.— «With the temperature change we see from day to night, the ground actually contracts and opens up, developing cracks and holes. So, by putting small seed on the ground, the frost actually works the seed into the soil. I’ll be using clover seed. This process is called frost seeding and it’s a great way to get seed into the ground without putting in a lot of time and effort.» —“Spring is the time to think about fall hunting” by Tom Wright WJRT-TV (Flint, Michigan) Mar. 29, 2009.
