Are you looking for a way to prevent soil erosion on your property? One effective solution is to use vegetative filter strips. But what exactly are vegetative filter strips and how do they work? Don't worry, we've got you covered. In this article, we will explore the benefits of using vegetative filter strips and explain how they work to prevent soil erosion.
What are vegetative filter strips?
Vegetative filter strips (VFS) are essentially strips of land that are used to filter and treat agricultural runoff. These strips are composed of vegetation, such as grass, shrubs, or trees, and are typically placed along the edges of agricultural fields, pastures, or other areas where water runoff is likely to occur. Their purpose is to filter and trap sediment, nutrients, and other pollutants before they can enter nearby bodies of water, such as streams, rivers, or lakes.
The Environmental Benefits of Using Vegetative Filter Strips
While vegetative filter strips are commonly known to aid in erosion control, their benefits aren't just limited to soil protection. Here are some of the environmental benefits that come with using vegetative filter strips:
-
Water Quality Enhancement - One of the most significant benefits of vegetative filter strips is their ability to remove pollutants from the water. As runoff water flows through the dense vegetation, it picks up sediment, nutrients, chemicals, and other contaminants. The strip's dense vegetation serves as a filter for these pollutants, trapping them before they enter the water body, and breaking them down over time through the plants' natural processes. This helps to improve the quality of water bodies, such as rivers, lakes, and coastal areas.
-
Biodiversity Promotion - Vegetative filter strips help in promoting biodiversity by providing habitats for different species of plants, insects, birds, and small animals. The dense vegetation and soil structure create a unique micro-environment that supports different species of flora and fauna.
-
Carbon Sequestration - Vegetative filter strips help in mitigating climate change and reducing the amount of carbon dioxide in the air through carbon sequestration. Vegetation absorbs carbon dioxide in the process of photosynthesis, and the resulting carbon is stored in the plant and the soil. The roots of the plants also help to stabilize the soil structure, contributing to carbon sequestration further.
-
Aesthetic Appeal - Vegetative filter strips add to the aesthetic appeal of the landscape. They break up the monotony of the landscape, providing a beautiful view and a natural feel. Additionally, vegetation can help in reducing noise pollution, which is helpful in busy areas.
-
Wildlife Habitat - Vegetative filter strips can provide habitat for wildlife, especially birds and small animals. The vegetation's micro-environment provides perfect homes for these creatures, including nesting grounds, food sources, and shelter.
By using vegetative filter strips as a soil erosion control measure, we can help protect the environment and enjoy many benefits beyond just soil protection. These strips are cost-effective to install and maintain and are beneficial in the long run. So, let us make it a priority to protect the environment by using vegetative filter strips.
The Economic Benefits of Using Vegetative Filter Strips
Vegetative filter strips (VFS) are not only effective in preventing soil erosion and reducing sediment runoff, but they also offer significant economic benefits that make it a worthwhile investment for landowners and farmers.
- Cost-effective - When compared to other traditional erosion control methods such as concrete or rip-rap, VFS is much more cost-effective to install and maintain.
- Increased land value - A well-maintained VFS system can increase the value of the land and crops. The system not only provides erosion control but can also create a more favorable microclimate for the crops to grow.
- Tax incentives - There are a variety of tax incentives offered for landowners that implement VFS. These incentives can vary depending on the state and region but generally include deductions on property taxes and federal tax credits.
- Protects water quality - By reducing sediment runoff, VFS helps protect the quality of water in the local watershed. This can lead to a positive impact on the availability and quality of water for livestock and irrigation purposes.
- Reduces maintenance costs - Since VFS helps reduce erosion, the maintenance costs associated with land restoration and repair are significantly reduced. This can translate into long-term cost savings for landowners and farmers.
- Create additional income streams - In some cases, VFS systems can be used to grow crops or raise livestock. This allows landowners to diversify their operations and create additional income streams.
Overall, the economic benefits of using vegetative filter strips are vast and cannot be ignored. Not only do they provide excellent soil erosion control, but they also offer long-term cost savings, tax incentives, and increased land value.
How to Properly Design and Install Vegetative Filter Strips
Vegetative filter strips are an effective way to prevent soil erosion around farms, construction sites, and roadsides. However, it is important to design and install them properly to ensure their effectiveness. Here are some key steps to follow.
-
Determine the slope and runoff area
The first step is to assess the slope of the area and the runoff area. For instance, if the slope is steeper, the filter strip should be longer, and the width should be wider. The runoff area will determine the amount of vegetation required to filter the sediments effectively.
-
Choose appropriate vegetation
The plant species used in the filter strip play a crucial role in its effectiveness. The plants must be able to tolerate wet and dry conditions, accommodate seasonal changes, and remain robust to withstand the effects of the runoff water. In general, native grasses, legumes, and other deep-rooted perennial plants are the best choices for a vegetative strip.
-
Determine the appropriate dimensions
Once the vegetation has been chosen, it’s important to determine the appropriate dimensions for the vegetative strip. As a general rule, the width of the strip should be 10 feet wide, but this may vary with the slope, runoff area, and vegetation used. The length of the strip should be determined by the amount of time it takes for the runoff to flow through the filter strip without overflowing.
-
Prepare the site
The site must be prepared before planting. This involves removing any existing vegetation, tilling the soil, and smoothing the surface of the land. The site should also be leveled to ensure a uniform slope and remove any low spots.
-
Plant the vegetation
Once the site is prepared, the vegetation can be planted. To improve the chances of success, it's important to follow planting instructions carefully, including the depth and spacing of planting. The seedlings should also be properly watered and maintained until they are fully established.
Overall, the proper design and installation of vegetative filter strips can significantly reduce soil erosion and protect the environment. By carefully assessing the site, selecting the appropriate vegetation, and following the necessary steps for preparation and planting, the filter strip can effectively filter sediments, chemicals, and other pollutants and preserve the health of local waterways.
Case Studies of Successful Implementation of Vegetative Filter Strips
Vegetative filter strips have been used in various locations to prevent soil erosion and reduce environmental pollution. Some of the successful case studies of implementing vegetative filter strips are:
-
University of Missouri
The agriculture experiment station at the University of Missouri conducted a study on the effectiveness of vegetative filter strips in reducing soil erosion and water pollution. The study showed that filter strips reduced soil erosion by 70%, decreased sediment load by 86% and reduced nitrogen concentration in surface runoff by 45%.
-
Northern Great Plains
A long-term study conducted on agricultural land in the Northern Great Plains showed that vegetative filter strips reduced soil erosion by 90% and sediment loss by 95%. The study also showed that vegetative filter strips enhanced soil quality by increasing nutrient cycling.
