Broadcast seeder machine. In agriculture, gardening, and forestry, broadcast seeding is a method of seeding that involves scattering seed, by hand or mechanically, over a relatively large area. This is in contrast to: precision seeding, where seed is placed at a precise spacing and depth;
Hand-pushed broadcast spreader. A broadcast seeder, alternately called a broadcaster, broadcast spreader or centrifugal fertilizer spreader (Europe) or "spinner" (UK), is a farm implement commonly used for spreading seed where no row planting is required (mostly for lawns and meadows: grass seeds or wildflower mixes), lime, fertilizer, sand, ice melt, etc., and is an alternative to drop ...
Aerial seeding helicopter Aerial seeding from a Hughes 500 helicopter. Aerial seeding is a technique of sowing seeds by spraying them through aerial mechanical means such as a drone, plane or helicopter. When the purpose is reforestation, it is known as aerial reforestation. Aerial seeding is considered a broadcast method of seeding. [1]
broadcast seeding A method of seeding that involves scattering seed over a relatively large and imprecise area, either by hand or mechanically, as opposed to precision seeding and hydroseeding. Broadcast seeding is easier and faster than seeding in rows but usually requires more seed and may result in overcrowded and uneven distributions of ...
A seed rate of about 100 kg of seed per hectare (2 bushels per acre) is typical, though rates vary considerably depending on crop species, soil conditions, and farmer's preference. Excessive rates can cause the crop to lodge, while too thin a rate will result in poor utilisation of the land, competition with weeds and a reduction in the yield .
The result is an increased rate of germination, and a much-improved crop yield (up to eight times compared to broadcast seeding [7]). The use of a seed drill also facilitates weed control. Broadcast seeding results in a random array of growing crops, making it difficult to control weeds using any method other
In the meantime, the stable imprint protects the seed from wind erosion and desiccation from exposure to the sun. [12] Broadcast seeders can be attached to the frame assembly or grain boxes mounted in front of the imprinting roller, so that seed is dropped in front of the roller which presses the seed into the soil. [2]
Hydroseeding is an alternative to the traditional process of broadcasting or sowing dry seed. A study conducted along the lower Colorado River in Arizona reported that hydroseeding could be used to restore riparian vegetation in cleared land. [2] The slurry often has other ingredients including fertilizer, tackifying agents, fiber mulch, and ...
