Broadcast seeding

This is in contrast to: Broadcast seeding is of particular use in establishing dense plant spacing, as for cover crops and lawns.

Broadcast seeding works best for plants that do not require singular spacing or that are more easily thinned later.

[1] After broadcasting, seed is often lightly buried with some type of raking action, often done using vertical tillage tools.

Incorrect depth, if too deep, would result in germination that would not allow the young plant to break the surface of the soil and prevent sprouting.

If they are not sown evenly then there would be a lack of various nutrients from sunlight, oxygen, et cetera, in many crops or plants.
