HydroSeeding which is sometimes also called hydraulic mulch seeding, hydro-mulching, or hydraseeding) is a planting process in which a slurry containing seed, hydro seeding mulch, fertilizer and a tackifier (bonding agent) is sprayed onto the ground. The slurry is transported in a truck or trailer mounted tank to the job site and sprayed over prepared ground in a uniform layer. Hydro seeding offers many advantages to the traditional process of broadcasting or sowing dry seed. It promotes quick germination and inhibits soil erosion. It is also a very cost effective alternative to sod and offers a significant cost savings as well as many other benefits.
How HydroSeeding Works
Virtually any grass or erosion control seed that can be planted by seed can be hydro seeded. This includes any sun or shade lawn seed, athletic field mixes, pasture mixes, native grasses, wildflowers, roadside mixes and erosion control mixes. The nutrient rich slurry helps promote fast germination. The hydro seeding mulch helps keep the soil moist to enable the seed to germinate quickly and unlike straw or hay contains no weed seed. The tackifer in the mix acts like a glue to hold the mulch in place and to help prevent washout in the case of heavy rains.
Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development and construction. Effective erosion controls are important techniques in preventing water pollution and soil loss.
Erosion controls are used in natural areas, agricultural settings or urban environments. In urban areas erosion controls are often part of storm water runoff management programs required by local governments. The controls often involve the creation of a physical barrier, such as vegetation or rock, to absorb some of the energy of the wind or water that is causing the erosion. On construction sites they are often implemented in conjunction with sediment controls such as sediment basins and silt fences.
