Hydroseeding is a fast and easy method to stabilize slopes by applying mulch, seed, and fertilizer in a sprayed mixture. Jet agitated hydroseeding systems mix materials thoroughly in minutes using high-volume jets with few moving parts. Aerial hydroseeding uses helicopters to apply large volumes of slurry over wide areas using GPS for precision. Hydroseeding works well because it suspends seed in a nutrient-rich slurry, triggers germination, seals in moisture with mulch, and places seed at the right depth for growth.
