Drill Seeding

Drill seeding is a way of placing seeds within small furrows in the soil surface at a relatively uniform rate. Many species, such as fourwing saltbush demonstrate greater emergence when drill seeded compared to other seeding approaches [1]. Warm seeded species tend to do well when placed ¼ - ½ inch deep into the seed bed. For drill seeding, as well as broadcast seeding, seed size can modify seeding rates. For example, small seeded species can separate from the seed mix during the seeding operation [2]. This can be solved by the use of seedballs.
