Hydromulching is a one-step process where seed, fertiliser and mulch are combined together in water with a special, biodegradable binder. The resulting slurry is sprayed onto the soil surface providing mulch interlocking mat that retains moisture for seed germination. Spraygrass®prefers high-quality Woodfibre as its main mulch material but also uses Straw and Sugarcane products which are available locally in Australia.
The mulch is coloured with a non-toxic green dye to give the impression of immediate coverage and to help identify areas requiring ongoing treatment. The dye then fades out of the fibre as
On difficult slopes, additional Binders are used to increase the effectiveness of the application. Hydromulching is best suited to higher rainfall areas such as coastal regions.
Hydromulching, using Australian Native Seed, was developed by
Many sites can be rehabilitated with grass seed but there is an increasing demand for the hydromulching of disturbed areas with seeds of Australian native trees, shrubs and creepers.
We recommended that whenever possible, areas to be seeded should be topsoiled. Ideally, topsoil should be tested from an authorised laboratory to ensure it has the correct ingredients to facilitate the growth of grass and native seeds. Prior to topsoiling, the soil should be tilled (up to 200mm deep) to further facilitate the highest possible yield. If topsoiling is impracticable, the area should be tilled using
Further yield gains can be achieved by clearing the area of weed growth, large stones or other debris.
Spraygrass recommends a Full Soil Chemistry test to determine if additives are required for the Hydromulch mix or applied directly into the soil.
