STRAWMULCHING is a two stage process -
1. Hydroseeding - Seed and fertiliser are uniformly mixed and agitated in solution with water. This is sprayed by truck mounted canon or hand-held hoses onto the soil surface.
2. Straw Mulching - Bales are fed into a “Straw Mulcher”. The straw is flailed, spun through a turbine and blown at high velocity through a barrel to spread evenly across the Hydroseeded surface. At the barrel tip, a fine atomised spray of bitumen or Tackifier/Binder is introduced into the straw matrix.
Straw mulching is used on a large range of disturbed areas, roadside batters, quarry restoration, dam construction, sand dunes, construction sites and estates etc.
Main Advantages of Straw Mulching
-
Suitable for harsher conditions, impoverished soil.
-
Straw layer provides microenvironment - seed will germinate when conditions are right
-
Raindrop impact dissipated
-
Surface water flow slowed by straw matrix
-
Seed not blown by wind
-
Mulch layer breaks down to add organic material to soil
