Spray on grass

Hydraulically sprayed growth mediums are a cost-effective grass growing technique used for erosion control on degraded landscapes. Spray on grass seed is known as hydroseeding. It is a grass seed application technique that uses a combination of grass seed, water, mulch fiber and additives such as fertilizers. A tackifier or bonding agent is used for better integrity of the mixture when applied to soil. This article highlights aspects of hydroseeding and evaluates the benefits of using GRT: Enviro-Binder for erosion control. 

Hydroseeding challenges in Australia

There are many challenges to use of hydroseeding in Australia. There are often limitations in the attempt to reduce erosion and this has raised a lot of conflicting results. These are some of the challenges:

  • Takes a lot of soil preparation.
  • Seed may spray out in one clump.
  • Takes several applications over a few weeks for results.
  • Leaves green stains on exposed clothing and skin.
  • Must follow extensive instructions precisely to see any results.
  • More expensive than other options.
  • Native species poor seedling establishment.
  • Logistics of water available close to the planting site. 
  • Uses a lot of water. 
  • Difficulty in calibration of application rates.

Types of hydroseeding methods.

The different types of hydroseeding aren’t any different from planting grass seed the traditional way just the spraying aspect which makes the difference. The two types of traditional grass seeding / establishment are:

  • Using traditional seeding. 
  • Laying turf or sod. 

Both hydroseeding processes involve preparation of the ground in the following ways:

  • Removal of rock and debris.
  • Soil amelioration with organic matter.
  • Soil smoothing by grading and lightly firming it.
  • Seed spraying via hydroseeding machine.
