Seeders , mounted on flotation-wheeled vehicles, can sow alfalfa fields rapidly and accurately. These machines work well on fluffy, dry, sandy soils that cannot be firmed by rolling. Seed is blown onto the soil from delivery tubes spaced 6 to 12 inches along the booms. Lightly packing, dragging a chain, or harrowing will cover seed. The main advantage to this type seeder is rapid speed.
Producers can plant several acres per minute, an important point just before predicted rains.
Aerial broadcasting onto properly prepared seedbeds is another method used to plant alfalfa with good success. Be certain to use an aerial applicator experienced in broadcasting alfalfa. Because uniform application can be a problem with broadcast planting, two passes in a crossing pattern are often required. After aerial broadcasting, it is advisable to roll fields to assure good soil contact with seed. When establishing alfalfa on steep slopes or otherwise erosive or shallow soils, it is suggested that minimum tillage be used for seedbed preparation.
