It is a planting process that uses a slurry of seed and mulch. It is often used as an erosion control technique on construction sites, as an alternative to the traditional process of broadcasting or sowing dry seed. The hydroseeding slurry is transported in a tank, either truck-mounted or trailer-mounted and sprayed over prepared ground. Helicopters have been used to cover larger areas. Aircraft application may also be used on burned wilderness areas after a fire, and in such uses may contain only soil stabilizer to avoid introducing non-native plant species.
Hydroseeding is an alternative to the traditional process of broadcasting or sowing dry seed. A study conducted along the lower Colorado River in Arizona, the United States found that hydroseeding could be used to restore riparian vegetation in the cleared land.
The slurry often has other ingredients including fertilizer, tackify agents, fiber mulch, and green dye.
