Soil erosion is when the top layer of soil is worn away on a certain area of land. This can occur naturally, through wind and rain, or human activities.
Soil erosion can ruin the aesthetics of the land and massively jeopardise your ability to use the land for growing crops and so forth. Keeping the land secure with methods like revegetation and erosion control products is a great place to start.
Fields that have been susceptible to overgrazing or stripped of their vegetation tend to leave the soil exposed and therefore very prone to erosion. The topsoil of an area of land is the most nutrient-dense, healthy part, and if this erodes, the underlying soil will struggle even more so to fight erosion.
When topsoil disappears, you lose the organic matter and nutrients that plants need to thrive. The remaining subsoil is often harder, less permeable, and far less fertile.
This damage can make it difficult for the land to be used to grow crops and plants. Beyond agricultural concerns, soil erosion affects water quality, increases sediment in waterways, and can lead to costly land rehabilitation projects.
Protecting your topsoil delivers benefits that extend well beyond keeping dirt in place. Understanding these advantages helps justify the time and investment in proper erosion control measures.
The cost of prevention is almost always lower than the cost of fixing severe erosion damage. Once gullies form and topsoil is lost, restoration becomes a major undertaking.
Trees are probably the best way to control erosion naturally. Tree roots help to prevent the land from eroding when it comes to steep slopes.
Planting new trees is a good idea if the land is sloped, just remember to use some garden stakes when the tree is young. The root systems of established trees create a network that binds soil particles together and reduces water runoff velocity.
If you are developing in a new area, it's very important to preserve as much of the vegetation as possible. Protecting the plants and trees in the area will protect as much of the fertile soil as possible, and this is the kind of soil that has the natural ability to best fight against erosion.
Even groundcovers and grasses play a critical role. Their roots stabilise the surface layer while their foliage breaks the impact of rainfall and reduces the force of water hitting bare soil.
Geotextile fabrics provide an instant protective barrier while vegetation establishes. They work by absorbing rainfall impact, slowing water flow, and holding soil in place during the vulnerable early stages of revegetation.
Natural fibre products like jute and coir are particularly effective because they're biodegradable and break down after plants have established. For light to moderate slopes with good existing soil structure, this 620gsm jute roll offers excellent coverage and degrades naturally within 12 to 18 months once plants have taken hold.
Different erosion control mats suit different applications based on slope, soil type, and expected plant establishment time. Here's a quick comparison of common options:
For areas with severe erosion risk or steeper gradients, the 900gsm coir option provides superior durability and longevity, making it ideal for challenging sites where vegetation will take longer to establish.
If you're planting at the same time as installing matting, a slitted matting roll saves considerable time because the pre-cut openings let you plant straight through without cutting individual holes.
Coir logs are cylindrical erosion control devices filled with coconut fibre. They work brilliantly along drainage lines, at the base of slopes, and anywhere you need to slow water flow and capture sediment.
These logs create a physical barrier that intercepts runoff and allows sediment to settle out before water continues downstream. They're particularly useful in channels where concentrated flow would otherwise create gullies.
Choosing the right diameter depends on the water volume and slope gradient you're dealing with. For standard residential applications and gentle slopes, a 150mm diameter log handles typical drainage challenges without being oversized for smaller projects.
Larger commercial sites or areas with significant water flow require more robust solutions. The key is matching the log size to the expected flow rate and sediment load.
Hydromulch is a mixture of seeds, mulch, fertiliser and water. It is applied to soil to prevent it from eroding in the rain.
Hydromulch is extremely effective when it comes to minimising soil erosion. The slurry is sprayed onto exposed soil where it forms a protective blanket that holds moisture, prevents soil from washing away, and provides ideal conditions for seed germination.
This method works particularly well for large areas where laying matting would be impractical or too expensive. Road batters, dam walls, and broad acreage revegetation projects often use hydromulch as the primary erosion control method.
The application is quick compared to manual seeding and matting installation. A hydromulch crew can cover several hectares in a day, making it cost-effective for big jobs.
If you happen to have livestock, make sure you're aware of the areas in which they are grazing. If you begin to notice bare patches of land, move them away from this area.
Rotational grazing prevents animals from completely stripping vegetation from any single area. By moving stock regularly, plants have time to recover and maintain root systems that hold soil in place.
Pay special attention to areas near water sources and on slopes. These zones are particularly vulnerable to compaction and erosion when overgrazed.
Fencing off severely degraded areas and allowing them to recover fully often proves more economical than trying to maintain marginal grazing land. Once revegetated and stabilised, these areas can be gradually reintroduced to grazing rotations.
Soil erosion won't fix itself, and waiting only makes the problem worse and more expensive to address. Start with the most vulnerable areas on your property and work systematically through trouble spots.
Combining multiple methods delivers the best results. Use matting or logs for immediate protection, establish vegetation for long-term stability, and manage land use to prevent future problems.
