Soil erosion is a major problem for farmers and construction companies. Soil erosion experts suggest the use of different control measures that have proved to be effective as far as water retention is concerned. The problem is that most of the soil erosion strategies that have been used for a long time have failed terribly.
Soil erosion is rampant in sloppy areas. It is important to put up measures that will prevent soil from being washed away. Failing to take action could leave the affected area barren and short of water supply. It can also lead to the introduction of pollutants.
Here are the top strategies for soil erosion control:
Planting of grass and shrubs
Shrubs and grass are very good at preventing soil erosion. This is mainly because of the fact that plant roots normally hold the soil together.
This makes it difficult for it to erode. Besides, the leaves and branches also assist in reducing the velocity of raindrops. Such action prevents rain from dislodging the soil and eroding it.
Low spreading shrubs and ornamental grass are the best to plant because they cover the whole area and make it harder for water to wash away soil. This strategy can be used both in sloppy bare grounds because the main objective is to cover the surface of the ground.
Building of terraces
If you are trying to control soil erosion on embankments or very steep slopes, then planting grass or vegetation may not be very effective. The best strategy to use in this case is to build terraces in order to slow down erosion as the vegetation continues to grow and expands.
The good thing about this strategy is that terraces can be constructed using almost anything. You can use wood, biochemical solution, or concrete blocks. The idea is to create barriers that are strong enough to prevent soil from being washed away by heavy rains.
Geogrids are widely known for reinforcing and stabilizing embankments and slopes. This erosion control strategy is mainly used by people who want to prevent erosion in steep and sloppy areas. A Geogrid is a three-dimensional material meant to avoid and rectify erosion in embankments.
The geogrid is created by a layer of polypropylene that forms a mat containing numerous nodules.
A geogrid has the following advantages:
- The three-dimensional structure makes it easy to place the plant substrate
- It can be constructed with readily-available materials such as wood and concrete
- The mesh openings allow water and nutrients to pass easily
- It is an effective erosion control strategy for sloppy areas
Based on the incline of the embankment or slope, one of the best ways to prevent soil erosion is to create diversions. The main purpose of the diversions is to redirect the excess water along the slope using a predetermined path.
The best way to accomplish this is by creating open drains or ditches by digging along the slopes at regular intervals. Another way of making this strategy effective is to use gutters and pipes. All you have to do is find someone who can do a proper job in terms of installation.
Erosion control blankets
There is a wide variety of biodegradables, fiber, and mats available on the market today. All of them are designed with only one purpose which is to reduce the effect of water erosion on embankments and slopes. Rolled mats are made using mulch held together by mesh.
The mulch degrades gradually and allows vegetation to grow and cover the earth’s surface. The type of material you use largely determines the effectiveness of this strategy.
Soil erosion can do a lot of damage to any land if not controlled. The good news is that there are many strategies that can be used to control soil erosion. It is up to you to ensure that you use strategies that have been proved to work.
