What depth is necessary for burying fine grass and legume seeds to prevent loss from wind?

Burying seeds at a depth of at least half an inch is generally considered adequate for fine grass and legume seeds to prevent loss from wind. This depth ensures that the seeds are sufficiently covered to provide some protection from wind displacement while still being shallow enough to allow for successful germination.

Fine grass seeds and legumes often have small sizes and lighter weights, making them more susceptible to wind and surface disturbances. Covering them at this depth helps maintain moisture and provides an ideal environment for germination without suffocating the seeds.

Going deeper, such as one or two inches, may create difficulties for the seedlings emerging from the soil, as they require energy to push through the soil profile. A depth of three inches is excessive for these types of seeds and could inhibit their ability to sprout effectively. The chosen half-inch depth strikes a balance between protection from wind and ensuring optimal conditions for seedling development.
