Which of the following plants acts stabilizer of soil to check soil erosion?
The answer is leguminous crops as they check soil erosion.
How do you stabilize soil erosion?
When looking for ways to stabilize soil, first consider working with nature. If your yard is steep and hilly, terracing may be in order. However, some of the best solutions are often less labor intensive. Consider mulching exposed soil surfaces, overseeding your lawn, and strategically placing plants.
How do you stabilize soil?
Soil Stabilisation Techniques
- There are 3 main methods for soil stabilisation:
- Mechanical stabilisation. This category consists of physical processes such as compacting or tamping with machineries including rollers or rammers.
- Chemical Stabilisation.
- Polymer Stabilisation.
What are three types of soil stabilization?
There are three broad types of soil stabilization: biological, physical and chemical.
How do you stabilize black soil?
Of these, lime stabilization is one of the techniques which is in use for stabilizing black cotton soil from the past few decades. Use of lime reduces the high plasticity of black cotton and makes it workable. Also reaction between lime and soil makes the soil-lime mixture more strength resistant .
How do you stabilize soft soil?
There are dozens of soil stabilization methods. These methods include adding cement to the soil, adding chemicals to change the chemical or physical makeup of the soil, and mechanical methods such as compaction.
Which material is used for soil stabilization?
Through soil stabilization, unbound materials can be stabilized with cementitious materials (cement, lime, fly ash, bitumen or combination of these). The stabilized soil materials have a higher strength, lower permeability and lower compressibility than the native soil (Keller bronchure 32-01E).
What are the problems of foundation on black cotton soil?
So, Building a foundation in black cotton soil is so risky . The swelling and shrinkage of expansive soil cause the settlement of building. When dry, it is very hard, but it loses strength completely when wet. It results in the development of the cracks in house.
What causes spongy soil?
Spongy lawns are the result of excess buildup of old and dead grass material. Overly thick thatch not only makes the lawn spongy but can interfere with the plant’s ability to gather air, water, and fertilizer. The roots are forced to grow on top of the thatch and the sponginess increases.
Why do we need soil stabilization?
In civil engineering, soil stabilization is a technique to refine and improve the engineering properties of soils. These properties include mechanical strength, permeability, compressibility, durability and plasticity. As such, the soil should possess properties that create a strong foundation.
