High Quality Content by WIKIPEDIA articles! In agriculture, precision seeding is a method of seeding that involves placing seed at a precise spacing and depth. This is in contrast to broadcast seeding, where seed is scattered over an area. Although precise hand placement would qualify, precision seeding usually refers to a mechanical process. A wide range of hand-push and powered precision seeders are available for small- to large-scale jobs. Using a variety of actions, they all open the soil, place the seed, then cover it, to create rows. The depth and spacing vary depending on the type of crop and the desired plant density. 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. Depending on the device, precision seeders may place only one, or a very few seeds per position. This is an advantage, in that it saves seed and it avoids crowding, or the need for thinning, allowing plants the space to grow efficiently.
