Calibrating Your Rangeland Drill
DVD

Diverse plant communities are essential for the health and vitality of our Nation's rangelands.
When rangelands have been devastated by wildfires, overgrazing, mining or weed infestations,
they need to be restored. Seeding in rough and uneven terrain is not easy. The rangeland drill
was developed for rangeland restoration beginning in 1951. Since then, the rangeland drill has
become a sophisticated piece of equipment that can deliver more diverse seed mixes in precise amounts. This DVD will help you learn how to properly calibrate a traditional or a minimum-till drill
so you will get the desired results without wasting valuable seed.
