Injection seeders are devices that direct the output of small "seed" lasers into the cavity of a much larger laser to stabilize the latter's output. Most seed lasers are stable, single-frequency lasers that emit within the linewidth of the larger laser's gain medium .
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 ...
United Rentals, Inc. is an American equipment rental company, with about 16 percent of the North American market share as of 2022. [5] It owns the largest rental fleet in the world with approximately 4,700 classes of equipment totaling about $19.3 billion in original equipment cost (OEC) as of 2022. [3]
The Super Seeder is an advanced agricultural machine than Happy seeder, engineered to revolutionize traditional farming methods. It offers an efficient, time-saving solution, allowing farmers to sow wheat seeds directly after rice harvest without the need for prior stubble burning, thereby contributing significantly to environmental preservation.
The depth and spacing is generally adjustable to accommodate a range of crops and the desired plant density; the degree of adjustability depends upon the chosen seeder. [ 3 ] In commercial production, precision seeding is an alternative to placing larger quantities of seed in a row, by dribbling seed or setting several seeds in each position.
1902 model 12-run seed drill Modern air seeder and hoe drill combination. The invention of the seed drill dramatically improved germination. The seed drill employed a series of runners spaced at the same distance as the plowed furrows. These runners, or drills, opened the furrow to a uniform depth before the seed was dropped.
Various machines meter out seeds for sowing in rows. The ones that handle larger seeds tend to be called planters, whereas the ones that handle smaller seeds tend to be called seed drills, grain drills, and seeders (including precision seeders).
