Hydroseeding is the application to the soil of a seed and water slurry that contains fertilizer, tackifier, fiber mulch and other amendments as specified. Hydroseed applications assist to mitigate erosion damage, providing stability to the seed as it germinates.
Hydroseed is a proven technique for the revegetation of barren slopes associated with site development. It has been successfully employed resource development sectors such as forestry, mining, utility construction and urban development. Mulch, tackifier and other components provide temporary erosion control until the vegetation cover develops.
Used throughout BC since the 1950′s, successful hydroseeding relies on specifications developed for the site including:
- seed mix design and application rate
- soil fertility requirements, plus post treatment considerations
- tackifier rates for the soil type and erosion hazard
- mulch rates adapted for the site microclimate
It is good practice to hydroseed as soon as possible. This will, of course, allow your seeds more time to germinate and also maintain the amount fines on the soil surface. When no erosion protection is present, the fines in the soil profile filter out and creating gullies and a smoother surface. This makes it difficult for seeds to remain in place and take root. Prompt application of hydroseeding and erosion control measures will ensure the fastest revegetation on your site.
Experience in planning and design must be complemented by appropriate equipment and application techniques to ensure effective hydroseeding results.
