precision seeding, where seed is placed at a precise spacing and depth; hydroseeding, where a slurry of seed, mulch and water is sprayed over prepared ground in a uniform layer. Broadcast seeding is of particular use in establishing dense plant spacing, as for cover crops and lawns. In comparison to traditional drill planting, broadcast seeding ...
