Editor's Note: This article from 2001 showed up in a recent search of No-Till Farmer's most popular web articles, so we thought we'd share it again as a resource for comparing no-till air seeders and no-till drills. Feel free to add your thoughts about air seeders vs. drills in the comment section below.
When it comes to making a decision on whether to purchase an air seeder or drill for no-tilling soybeans, small grains or other crops, don’t expect to reach any quick and easy answers.
The popularity of air seeders has been growing in recent years, especially among farmers who crop several thousand acres, observes Vernon Hofman, extension agricultural engineer at North Dakota State University.
Most no-till air seeders are available in 55- to 60-foot widths and can cover 200 acres a day comfortably at a seeding speed of 5 to 6 mph, adds Elmer Kaskiw, agricultural representative with the Manitoba Department of Agriculture and Food at Shoal Lake, Manitoba.
