Concept
Sowing
Summary
Sowing is the process of planting seeds. An area or object that has had seeds planted in it will be described as a sowed or sown area.
Among the major field crops, oats, wheat, and rye are sown, grasses and legumes are seeded and maize and soybeans are planted. In planting, wider rows (generally 75 cm (30 in) or more) are used, and the intent is to have precise; even spacing between individual seeds in the row, various mechanisms have been devised to count out individual seeds at exact intervals.
In sowing, little if any soil is placed over the seeds, as seeds can be generally sown into the soil by maintaining a planting depth of about 2-3 times the size of the seed.
For hand sowing, several sowing types exist; these include:
Flat sowing
Ridge sowing
Wide bed sowing
Several patterns for sowing may be used together with these types; these include:
Rows that are indented at the even rows (so that the seeds are
Symmetrical grid pattern – using the pattern described in The Garden of Cyrus placed in a crossed pattern). This method is much better, as more light may fall on the seedlings as they come out.
Hand sowing or (planting) is the process of casting handfuls of seed over prepared ground, or broadcasting (from which the technological term is derived). Usually, a drag or harrow is employed to incorporate the seed into the soil. Though labor-intensive for any but small areas, this method is still used in some situations. Practice is required to sow evenly and at the desired rate. A hand seeder can be used for sowing, though it is less of a help than it is for the smaller seeds of grasses and legumes.
Hand sowing may be combined with pre-sowing in seed trays. This allows the plants to come to strength indoors during cold periods (e.g. spring in temperate countries).
In agriculture, most seed is now sown using a seed drill, which offers greater precision; seed is sown evenly and at the desired rate. The drill also places the seed at a measured distance below the soil, so that less seed is required.
