Soil Erosion Problems and Solutions

Erosion Control

Why You Should Apply Jute Netting to Your Garden

Netting made from jute can be very useful in your home garden or landscaping project as a method to prevent erosion and encourage plant growth. Jute netting helps reduce soil erosion and provides cover for regrowth. Try these tips for using jute erosion control netting in your garden.

Erosion Control Blankets

Erosion control blankets are biodegradable, open-weave blankets that create short-term shelter for seeding and establishing vegetation on bare and sloped landscapes. You might have seen large erosion control blankets on roadsides, where they are often placed to support emergent vegetation (normally grass) for erosion prevention.

These blankets are made of natural, biodegradable fiber — often jute, straw, or coir. The natural material protects bare soil and newly seeded areas against rain and wind. This allows seeds to germinate and grow root systems, which will eventually lead to established plants. As plants or grasses grow through the mesh, they are stabilized. Later, the erosion control netting decomposes to allow further growth. 

Benefits of Jute Netting

Made from the woven fibers of the jute plant, jute netting, or mesh, is a biodegradable, natural, and flexible material used for temporary erosion control and selective plant establishment. Jute mesh has openings in the weaves, which trap seeds and provide a protective environment for germination. This mesh allows light and water to pass through, encouraging strong plant growth and enhanced mineral content in the soil. 

How to Use Jute in Your Garden

Jute netting can help prevent erosion on riverbanks, embankments, slopes, and other landscape features. It is commonly applied to roadside and general landscaping, garden and plant beds, wetland and land reclamation, and to protect other land features prone to erosion. 

Erosion control netting can also be applied alone as an alternative to wood chips or straw, on flat sites as a method of dust control, or to support seed germination. To use jute mesh correctly, first you must clear away debris and excess weeds from the slope or plain where you plan to place the netting. Apply netting up and down the slope, never along the contour. Anchor the netting every few feet as you go, and overlap sections. 

This material doesn’t work in every situation where soil erosion and water runoff is a problem. Jute netting will not be helpful in areas with steep, sandy slopes, very rocky hills, or significant fire-burned vegetation. It should also not be used in areas where runoff is expected to be high. 

You might want to try coir blankets for areas with slightly higher runoff and erosion problems. On average, coir mats provide solid support for up to five years, which is enough time to allow vegetation to take root, grow, and stabilize. In addition, coir blankets and mats are relatively easy to install. 

Most gardeners will find jute erosion control netting useful as a way of protecting their soil from wind and water damage, as seeds take time to germinate and become established. Use these tips when using jute in your garden, and add coir blankets for bigger erosion problems.

Best Methods for Water Runoff Control

Damage caused by water runoff can quickly turn a beautiful garden into a muddy marsh. Water carries soil, wood chips, grass clippings, and other debris that can cause erosion and pollute public water. If you’re looking to preserve the structural integrity of your landscape and avoid erosion, try one of these ideas for better water runoff control. 

Berm

A berm is a small hill covered with rocks, grass, and other plants that divert water around an area you’d like to protect. Water flows toward the berm from one direction, and on the opposite side is the area you’re protecting. A berm is a good option for a relatively quick fix to water runoff control. Make sure to follow a detailed guide when building a berm. 

Swale

A swale is a shallow depression that follows the natural contour of a slope, diverting water from one place to another. Rocks in the swale help slow the speed of water, allowing it to sink into the soil. Swales are also used to direct water toward a dry well or around the base of a house (to avoid basement flooding). You can enhance a swale by using a landscaping blanket, compost filter sock, or other product to increase effectiveness. 

Sediment Control Products

A number of products on the market assist with water runoff control. The list can be somewhat overwhelming, including types of liners, cloth, filter systems, blankets, mesh baskets, barriers, turf, mulch, mats, and much more. But not all products are created equal, and it’s important to do your research to find the best fit for your garden or landscape issue. 

If your problem is minimal water runoff and significant sediment buildup, you could try a compost filter sock. This is a great option if you have some water runoff but want to control erosion without disturbing the ground in an area with established vegetation. 

Permeable Hardscape

Hardscape encompasses the man-made features of landscape architecture, such as paths or driveways. If one of your problems has been water moving over or around hardscape, you might consider installing paving materials that have small gaps to allow water to seep through them. This will keep the surface dry while eliminating runoff. Small-scale jobs, such as permeable walkways, can be DIY projects, but you might need to hire professionals to tackle a driveway or other large project. 

Grade Broad Surfaces

Landscape grading is the basis of landscape design and can help significantly with water runoff control. This is a more expensive option, which will require an excavator or rental equipment. However, if you need extreme water runoff control — perhaps your basement is continually flooded — then it’s an essential step. 

With so many products on the market to address water runoff control, the options are practically endless. Luckily, this means you’ll be able to stop excess water runoff and get the most out of your  landscape. Explore the options to find out which products would work best to address the water runoff issues you’re facing.

Landscape Netting for Slopes

If it seems impossible to keep your growing space seeded due to adverse conditions, then you might need landscape netting for slopes. Landscape netting is beneficial for shielding and keeping seeds in place and is easy to install in gardens or landscaped areas.

What Is Landscape Netting?

In certain areas, such as on slopes or hills, vegetation might not grow well due to many factors. The seeds might not be able to stay in one place because of the slope, or the area might be affected by wind or water erosion. Thus, landscape netting protects the seeds and keeps them from being swept away by water or windy conditions.

Additionally, birds or other animals might be eating the seeds, leaving fewer to grow into plants. Because landscape netting defends the seeds, they can grow and flourish into seedlings and, ultimately, mature plants. Without protection from landscape netting, the seeds and seedlings might never have the chance to reach full maturity.

Landscape Netting Uses and Applications

Landscape netting is manufactured in many shapes and sizes. Typically, it’s made of coir (the durable, all-natural fibers from coconut husks), jute, straw, or synthetic materials. If you’re concerned about your ecological footprint, you could use a coir, jute, or straw variety of landscape netting for slopes, as these materials are all biodegradable and eco-friendly thanks to their natural fibers.

It’s wise to use landscape netting for slopes and other areas characterized by hilly terrain. In addition to slopes, landscape netting can also be advantageous in areas prone to erosion. You can apply landscape netting to small areas as well as large-scale landscaping or agricultural projects. No matter where you install the landscape netting, you can be confident in its ability to maintain and control erosion.

How to Use Landscape Netting for Slopes

First, prepare the installation area by removing any debris, and then compact the soil. Next, you will need to till the top few inches of soil where you’re installing the netting. Now you’re ready to plant and seed the area as you would normally. It’s important to dig a small trench at the top of the slope to secure the landscape netting in place. Once you have secured the netting to the trench using staples or stakes, backfill the trench and compact the surrounding soil. 

The next step is to unroll the landscape netting from the trench and down the slope. Keep pulling the netting taut, as it should be flat against the soil. After the netting covers the slope, anchor it to the soil. Finally, you’ll need to dig another trench at the bottom of the slope to hold the end of the netting so it doesn’t shift. Don’t forget to water the slope thoroughly once you’ve finished installing the netting. Over time, the netting will degrade into the soil.

Landscape netting has many advantages and will assist you in growing any kind of vegetation in any environment. Try landscape netting for slopes to keep your seeds safe from the elements.

How Does Soil Erosion Affect Soil Fertility

The usual image that comes to mind when thinking about erosion is beach erosion and other areas where the land has very noticeable changes due to erosion. It’s often straightforward to see the impact that erosion has on these areas because there are visible changes to the landscape. Soil erosion can result in changes that aren’t visible that can have just as devastating an impact as a beach disappearing over time. 

As a gardener, you may find yourself in a situation where you have to deal with soil erosion, as it can harm the fertility of the soil in your garden.

What is Soil Fertility?

Soil fertility is the concept of how well the soil can provide a habitat for life. Rich, fertile soil is the home of diverse organisms and is able to grow a variety of plants that result in a plentiful harvest of top-quality fruits and vegetables. A backyard garden that has fertile soil doesn’t need any amendments to it to ensure that your crop does well. A garden that has soil fertility issues will struggle to yield a quality harvest.

What Factors Contribute to Soil Fertility?

Several factors contribute to soil fertility. The soil needs to be deep enough for roots to grow and water to be retained in it. Weak root growth or water that evaporates too quickly will result in plants that don’t thrive. There also needs to be some drainage in the soil. More clay-based soils can result in poor drainage. This drainage issue can result in plants having their roots rot, and often ends in the plant dying. Also, drainage issues often mean that the soil is too hard without aeration for the roots.

The amount of organic matter that is found in the soil is also essential. Organic matter helps with soil structure and moisture, along with putting minerals and nutrients into the soil. A lack of organic matter will often result in plants that are probably not getting the right mix of nutrients to grow. Fertile soil also has the perfect pH. It should range from 5.5 to 7.0 for most plants. There are some plants, such as blueberries, that prefer soil outside of this pH range, but for most plants, this range is the sweet spot.

Another aspect of soil fertility is the other organisms in the soil. Some gardeners think of every organism that invades their garden as a pest or a problem that needs to be eradicated, but that’s not always the case. There are beneficial microorganisms that live in the soil that help plants grow, such as mycorrhizae. Poor soil quality often results in the death or migration of these microorganisms. 

Why is Soil Fertility Important?

Often, when there are issues with the growth of a plant or the harvest, there are two potential causes. One is pests, while the other is soil fertility. Soil fertility is vital for the soil to provide the perfect medium for any plants to grow. Problems with the fertility of the soil will show up during the growing season. Gardeners may find that their seedlings don’t grow as they should or that the leaves of the plants are yellowing when they should be a healthy green. The fertility of the soil must be addressed to help treat any issues and prevent them from occurring again in the future.

How Does Erosion Affect Soil Fertility?

Soil erosion can have an impact on soil fertility. The soil in your garden is in layers that have been deposited over time. Often, the top layer that you plant your garden in is called topsoil. Erosion erases away the top layers of the topsoil over time. As topsoil is often one of the most fertile areas, you’re losing some of the qualities that make your soil fertile. Loss of soil fertility can be a huge problem for gardeners that can’t be ignored.

Testing Your Soil

One of the first things that should be done if you think there’s a problem with the fertility of your soil is to test it. Testing is a valuable tool that can help you address any lack of nutrients or minerals in the soil that’s impacting your crops or flowers. There are two options when it comes to testing. 

You can pick up a DIY kit that allows you to take several samples from around your garden and test the soil yourself. These kits can require that you follow the directions exactly to get the correct results, so it is imperative to read the instructions carefully a few times before you get started. 

The other option is to send your soil samples off to a lab to have them tested for you. For this option, you’ll need to collect the soil using the directions they send. Usually, these directions are that you have to collect at an appropriate depth and in several areas to get an overall feel for your soil’s health.

Once you receive the test results, you can use them to amend the soil as needed. You may find that you need a general application of fertilizer to boost the nutrients in the soil or that you need only one particular nutrient. Problems with pH can also be found at this time. 

Soil Fertility Assistance

After you’ve tested the soil, you should also look into the physical nature of the soil. How deep does your garden bed go down? Does your soil contain clay? When it rains, does your garden become a muddy mess? Any of these issues should be adjusted. For instance, you can add lighter amendments to the soil that’s high in clay.

Soil erosion can cause issues with your garden and how well it will grow over the season. Adding minerals and nutrients to it may be necessary if the erosion has taken away too much of what makes your soil fertile. Testing your soil is one of the best methods of ensuring that your soil remains viable for this growing season and beyond. 

Economic Effects of Soil Erosion

In today’s changing climate, the effects of soil erosion are prevalent. While forest land, or land that is surrounded by or covered with vegetation, usually sees little effects of soil erosion, cultivated land certainly does. The practice of clearing land for agriculture serves to increase its vulnerability as unprotected land is susceptible to frequent and sustained soil erosion.

Erosion occurs when the land’s soil is not adequately covered in order to protect it from wind, water, and sand. This erosion causes the soil’s health to decline as well as affects surrounding resources such as air and water quality. Heavy flooding or storms can exacerbate the problem or be the cause of erosion in the first place. Overall, erosion can reduce the land’s ability to produce harvests and lead to economic hardship.

Economic Effects of Soil Erosion

In the United States alone, soil erosion accounts for $12 billion in losses. In comparison, Asia and Europe tally $3.5 and $4.5 billion respectively. Several industries are affected by the loss of soil quality or the degradation of crops and their yields. 

  • Meat and Dairy: Chicken, cattle, and swine are all affected by soil erosion. As the quality of their feed depletes, the quality of meat declines. Animals may be drinking water contaminated by runoff or their feed might not contain enough nutrients.
  • Fruits and Vegetables: When crops don’t produce their expected yield, prices go up. Supply and demand still rule the day and if production is reduced or quality degraded, prices may spike for produce that is usable.
  • Grains: Since grains are converted into feed for livestock and processed into bread and flour, the degradation of their quality has a trickle-down effect and finds its way into the bread on the dinner table.

Effects of Soil Erosion on the Environment

Rattan Lal, from the School of Natural Resources at The Ohio State University, describes the condition as such: “Soil erosion exacerbates soil degradation and vice versa. In some cases decline in soil quality, especially the weakening of structural units, precedes erosion. In others, erosion may lead to a decline in soil quality and set in motion the degradative trend. In fact, soil erosion can be a manifestation of soil degradation because it involves physical removal of soil in a vertical and/or horizontal direction and degrades soil quality. It is a natural process that has shaped the landscape and led to formations of fertile alluvial and loess soils. However, the acceleration of the process through anthropogenic perturbations can have severe impacts on soil and environmental quality.”

Those impacts include damage to lakes and streams from runoff. As disturbed soil is washed away and deposited elsewhere, natural water resources are inevitably impacted. This erosion wreaks havoc on the land by removing the topsoil and over time, reducing its depth. This depth reduction causes roots to struggle to take hold. Topsoil degradation means soil loses its ability to trap and filter water, diminishing its benefits.

The soil’s fertility is called into question as well as nutrients are washed away. Young plants might not stand a chance from the onslaught of wind and rain and may be lost altogether.

Sediment is a serious impact of soil erosion as the runoff has to go somewhere and turn into something. Nearby roads and neighboring properties might find sediment deposits. Long-term excessive erosion can lead to weakened bridges and other infrastructure. Sediment deposits might also accumulate downstream and cause flood hazards while disrupting fish spawning grounds. Sediment might carry pesticides and fertilizers in its make-up, leaving poisons in its devastating wake.

The economic impacts on environmental shifts caused by erosion are vast in possibility and depend on the affected area’s economic and industrial output.

Effects of Soil Erosion on Agriculture

Although it is difficult to assess agricultural losses because of the unpredictability of climate change and accompanying weather patterns, estimates of economic loss are heavy and impactful. Since tilled soil is more vulnerable than untilled soil, it usually suffers the worst effects of erosion and influences agriculture by lessening the land’s ability to produce crops.

Erosion carries away not just soil but also the nutrients it contains. Studies show that each ton of soil that erodes might contain the equivalent of 2.32 pounds of nitrogen and one pound of phosphorous. When these elements are carried away, they are deposited in places adversely affected by excess nitrogen and phosphorous, not to mention pesticides. Per-acre dollar estimates work out to fertilizer losses at a cost of $2.10 per ton of soil loss.

The impact on agriculture in terms of time is also weighty. Farmers spend crucial growing time preventing erosion or repairing its damage. Eroded areas must be leveled with additional cultivation as well as filling gullies created by runoff. Gradually, topsoil suffers and depth is lost. Seeds and seedlings might also be washed away, adding to crop and economic losses.

Conservation Practices and Erosion Control

There are methods to minimize the damage of soil erosion and possibly prevent it from occurring in the first place. The time to put these into practice is before the next rainy season or the next predicted storm.

  • Crop rotation: Alternating crops on the same land can maintain soil productivity.
  • Contour farming: Sloped land can be tilled to make elevations more consistent and furrows can be created to serve as reservoirs. Terraced planting has a similar effect as crops are planted in graduated platforms to deter erosion.
  • Strip cropping: Alternating crops to be cultivated with strips of sod-forming or matting textiles like coir blankets and logs can also work to minimize erosion.
  • Subsoiling: This method works by circulating the soil to increase root aeration and give water a place to go, providing better access to crops that need it for survival. 

Lal goes on to say that, “Estimates of the global extent of soil erosion are tentative and subjective, and need to be improved by using remote sensing, GIS and other modern techniques. Developing a credible database is crucial to identifying management strategies. Erosional hot spots of the world … are in need of coordinated efforts at the global scale to restore degraded ecosystems.’

Soil erosion and shifting climates both affect the viability of soil used in necessary, everday industries. With conservation methods and soil stabilization products, erosion can be reduced and prevented, salvaging one of the most important resources.
