South Australia has long suffered from severe erosion. This is no longer surprising because it is a known fact that the state has the driest land in the whole of Australia.
The tropical climate of the state is one of the primary reasons for its dry soil and erosion problems. The high temperature of the soil alters its properties and organic matter content, significantly affecting its ability to retain water.
When the soil lacks moisture and is too dry, it becomes susceptible to wind and water erosion. Soil erosion removes nutrients and organic minerals from the ground. As a consequence, the land experiences a decrease in its productive capacity.
Moreover, water erosion impacts roads, transportation, as well as aquatic life. Dust — which wind erosion carries — also brings respiratory problems to humans.
Another reason for the severe erosion problems in South Australia is poor farming practices.
Historically, European settlers who were not familiar with the unique climate of the state applied European techniques in farming and grazing. Unfortunately, these practices were more suited to the environment of the northern hemisphere, resulting in more harm than good to the soil in the state.
Grazing, especially in droughts or late summer, produces problems in soil compaction and brings risks for surface runoff. Tillage and stubble burning also increase the risk of erosion.
Fortunately, through the improvement of farming techniques and practices, the soil erosion rate in South Australia has declined. However, there are still soil losses from prolonged droughts or stormy seasons.
South Australia’s government has since been providing legislation to combat these erosion issues in the state.
State officials, for instance, authored the Soil Conservation Act of 1989 to educate local farming communities on how to improve land management and mitigate erosion. The act contains extensive information about the soil and natural resources of South Australia. These efforts are aimed at directing people to become more conscious about the land they are using and tilling.
In addition, the Soil Conservation Act requires the preparation of district plans on soil loss prevention. The plans come from the information gathered after careful planning and analysis.
There is also an initiative to implement a land condition monitoring programme. This strategy involves the monitoring of the soil and land resources of the state. Any information gathered from this initiative will help keep the local agencies updated on the risks of cropping lands to wind and water erosion.
While the state implements these legislations well and continues to benefit the state, there is still a need to create committed solutions from a team of soil scientists and experts to produce long-lasting results.
One way to achieve this is through successful science-based revegetation projects.
Revegetation is an effective method to manage and prevent soil erosion. Plants give anchor to the soil to prevent them from washing out or becoming airborne.
Furthermore, vegetation improves soil stability through mechanical and hydrological effects. The roots increase water infiltration into the soil through the pathways they create.
Extensive root systems can create interlocking grids for the soil layers. As a result, there is a reduction in the soil displacement rate. Plus, there is an increase in the stability of slopes as well as embankments.
The reality is that when erosion damages or depletes soils, they require more than conventional hydroseeding treatments. Only sustainable and proven revegetation programmes can rehabilitate the earth and restore environmental health in the long term.
This is where Erizon comes in as the perfect solution.
Known for unparalleled excellence in providing environmental solutions, Erizon continues to provide strategic revegetation plans for Australia.
At Erizon, we believe that each site is unique. As such, we implement systematic and tailored approaches to suit each revegetation project.
Our strategy always begins with an on-site visit to identify the characteristics of the land. Site inspection provides information on the previous usage of the land and specific environmental concerns and conditions.
A team of soil scientists and field experts surveys the field and collects soil samples. They then forward these samples to the laboratory for an extensive soil analysis. We also utilise modern 3D drones to map out the area in great detail.
From the results of the soil testing and site imaging, we analysed the best ways to optimise vegetative growth. We also assess the best seeding rate and the right amount and type of fertiliser to apply.
We believe in the value of client partnership and thus give informed recommendations to our clients after our site analysis.
Our team also selects the best species, applications, and erosion control products that suit the area. The correct choice of plant species will produce positive results and prevent time and money losses. We guarantee healthy soils that last for long periods.
It is vital to note that a successful revegetation project includes proper weed management. Weeds compete with other plants for moisture, nutrients, and light. Knowing this, we incorporate weed infestation prevention into our methods to increase seedling survival and growth.
We also implement an eco-friendly approach to save energy and minimise water requirements.
Erizon utilises modern equipment to ensure even mixing and application of our products. We built our HydroTrucks with an agitator for accurate area targeting. We use 3D drone technology to apply fertiliser and soil probiotics one or two months after seeding. We also use hoses and spray bars for excellent product application.
Our team of experts also researched and innovated the best revegetation products.
For instance, our EnviroSoil product is a perfect topsoil alternative for soils that cannot support plants. Made of thermally engineered organic fibres, seaweed extracts, and mineral blends, EnviroSoil rectifies and improves the rhizosphere’s growth potential.
The fibres also minimise erosion by providing an interlocking matrix. They can act as a food source for microorganisms for healthy plant growth.
Finally, Erizon conducts post-application monitoring to ensure that the project is going as planned and will produce positive outcomes.
Commitment is the quality that makes Erizon stand out.
We dedicate our time and effort to each of our projects from start to finish. Our highly trained professionals conduct regular site visits to immediately address any concerns that may arise during the project.
Twenty-five years of experience in the field has proven Erizon’s commitment to excellence and integrity. Over the years, our clients have witnessed the efficiency of our scientific solutions.
At Erizon, we provide a ‘Supply, Apply, & Guarantee’ approach. We supply comprehensive planning and solutions, apply the best site interventions, and guarantee 100% positive results.
Our tailored solutions communicate the value we give to every project. We don’t just offer solutions; we create specific answers. To do this, we conduct an extensive site examination and soil analysis using the latest technologies. From there, we choose the best plant species, products, and applications that give us productive outcomes.
Erizon believes in the value of innovation. Thus, we provide scientifically backed methodologies for each of our projects. Our research team and soil specialists ensure we implement innovative solutions and restricted-access equipment tailored for South Australia’s land and climate.
Lastly, it is our goal to provide a safe environment for everyone to live in. With this goal in mind, our only option in all that we do is excel.
