Often asked: How Does Terrace Farming Reduce Soil Erosion?

How does terrace farming help prevent soil erosion?

In terrace farming, a terrace is a piece of the sloped plane that is cut into a series of successively receding platforms, that resemble steps. This prevents rain from washing away soil, hence preventing soil erosion.

Does terrace cultivation cause soil erosion?

Via water and soil conservation, terrace farming ensures food protection and increases crop yield. It thus decreases soil erosion.

How does terracing prevent and control soil erosion on hilly areas?

How does the terracing shown in Figure 1 photo prevent soil erosion? Terracing keeps the soil from moving very far downhill since it will only get as far as the next terrace downhill. Water will also be slowed by the terraces and so will be less able to carry tremendous amounts of soil downhill.

What are the advantages and disadvantages of terrace farming?

The primary advantage of terraces is improved soil erosion control. Secondary advantages of terraces include elimination of grass waterways that can be difficult to maintain and reductions in flooding. Disadvantages include the capital cost of building terraces, and the time required to maintain terraces.

How do we prevent soil erosion?

You can reduce soil erosion by:

  1. Maintaining a healthy, perennial plant cover.
  2. Mulching.
  3. Planting a cover crop – such as winter rye in vegetable gardens.
  4. Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

What are the advantages of terrace farming?

Terrace farming ensures food security and increases crop yield by water and soil conservation. Thus it reduces soil erosion. In terrace farming, the interaction between water and fertilizer increase results in high yield.

Is terrace farming still used today?

Today, modern farmers are returning to the terrace farming practices used thousands of years ago as a more practical and productive way to raise the most food with the least water. Tea farmers also take advantage of terrace farming.

Why is terrace farming important?

Terrace farming prevents the washing away of soil nutrients by the rains. This leads to the growth of healthy crops. Secondly, it prevents the carrying away of plants by the heavy flowing rivers of water. Sometimes rain water carries away the crops leading to low crop yield.

What can you plant on hillside to prevent erosion?

Some plants that work well on slopes include:

  • Burning Bush.
  • Fragrant Sumac.
  • Japanese Yew.
  • California Lilac.
  • Creeping Juniper.
  • Dwarf Forsythia.
  • Snowberry.
  • Siberian Carpet Cypress.

What are the two powerful agents of soil erosion?

The agents of soil erosion are the same as the agents of all types of erosion: water, wind, ice, or gravity. Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away.

What are the major causes of erosion?

The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth.

Is terrace farming good or bad?

Terracing is one of the oldest means of saving soil and water. Existing literature and information shows that terraces can considerably reduce soil loss due to water erosion if they are well planned, correctly constructed and properly maintained. If not maintained, they can provoke land degradation.

Is terrace farming sustainable?

In fact, terracing is the only way really steep slopes can be farmed sustainably. Those lynchets, while not tillable, are not unproductive.

Is Step farming and terrace farming same?

Answer. In terracing, wide steps are cut around the slopes of hills to prevent soil erosion. Contour ploughing follows the “natural shape” of the slope without altering it. Terrace farming alters the shape of the slope to produce flat areas that provide a catchment for water.
