Hydromulching South Australia

Meeting The Challenges Of Soil Erosion

The challenges of soil erosion in South Australia require careful consideration to ensure that productive land is maintained. To meet these challenges, a range of solutions must be employed. These include both preventative and active measures.

Preventative measures involve adopting conservation practices that reduce or avoid the loss of topsoil. These include maintaining permanent vegetation cover over vulnerable areas, reducing soil compaction through grazing management, and increasing organic matter content through the utilization of crop rotation or green manures. These practices can help retain moisture in the soil, reduce surface runoff, and increase available nutrients for crop growth.

Active conservation measures involve physically intervening to reduce areas of active erosion or treat sites where erosion has already occurred. Examples include contour plowing, which creates terraces along slopes, and establishing grassed waterways and berms, which direct runoff flows away from susceptible sites.

Mulching, where organic material is spread over bare ground, is also used in South Australia, along with, revegetation/ reforestation projects to stabilise steep slopes and gabion walls to protect against run-off.

The Best Solution For Hydromulching In South Australia

Our clients all over Australia can attest to how we have provided revegetation solutions that meet the project’s needs and company goals. We offer cost-effective but proven solutions across the state.

Our rehabilitation programme always begins with an on-site survey. During the site visit, our scientists collect soil samples and conduct a thorough analysis of the soil. The results of the soil analysis enable us to formulate the optimal solution by specifying which seeds, nutrients, and additives will be most effective at the surveyed location.

Depending on the results, there are two types of hydromulching solutions we typically recommend – hydromulching HGM and hydromulching BFM.

Hydromulching HGM

Hydromulching Hydraulic Growth Medium (HGM) is a one-step process that is best for sites that already have sufficient irrigation. It works in all types of climates, including South Australia’s subtropical climate.

In this type of hydromulching, water is used to carry and spray seed, fertiliser, binders, cellulosic mulch, and tracking dye to the seedbeds.

Our solution is composed of organic mulch fibres, which are hygroscopic and can deliver up to 50% more water-holding capacity. These fibres have an increased ability to hold moisture and promote seed germination supporting vegetative growth while minimising erosion and reducing water requirements.

Hydromulching BFM

Our second option is Hydromulching Bonded Fibre Matrix (BFM) which is a heavy-growth medium. Compared to HGM, this option is best for revegetating areas with steep slopes and areas that experience high amounts of rainfall.

Hydromulching BFM involves a two-step application process.

In the first step, we apply water, seed, and amelioration to the surface to guarantee seed-to-soil contact. Ensuring the meticulous application of this step improves revegetation outcomes.

The second step involves spraying cellulosic mulch, binders, and tackifiers onto the surface. Doing so at a high application rate ensures we secure a more positive outcome.

BFM comes with a viscous bonding agent and interlocking fibres. Upon application, they form a protective cover over the treated area, which retains a high level of moisture. Through this, the ground gains protection against erosion for up to 18 months while promoting the best growing environment for native plants.
