Hydroseeding is a seed application method where seed is mixed with water, mulch, fertilizer, and tackifier (soil binder) in a mixing tank with mechanical agitation. Some mulches can provide immediate erosion control to a slope, similar to erosion blankets.
Application is made using a "cannon" or a hose with a nozzle. It is very effective where quick surface cover is needed to prevent surface erosion and for areas that need quick grass growth.
Hydroseeding uses include reclamations, erosion control, roadside ditches and commercial turf applications.
