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.

What does terrace farming prevent?

Terrace farming are step-like features. These step-like are usually cut out of mountainous areas. Using these method, it prevents rain from washing away soil, hence preventing 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.

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.

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.

Does step Farming prevent soil erosion?

Answer. Soil erosion occurs when the water with high velocity runs down washing the soil. As many terrace or step like slopes are present in terrace farming it reduces the speed as well as the quantity of water moving over the soil surface as a result of which it checks soil erosion by preventing it.

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.

What is terrace farming?

Terrace cultivation, method of growing crops on sides of hills or mountains by planting on graduated terraces built into the slope. Though labour-intensive, the method has been employed effectively to maximize arable land area in variable terrains and to reduce soil erosion and water loss.

Where is terrace farming common?

Terrace farming was invented by the Inca people who lived in the South American mountains. This farming method has made cultivation of crops in hilly or mountainous regions possible. It is commonly used in Asia by rice-growing countries such as Vietnam, Philippines, and Indonesia.

What are the methods of controlling erosion?

How to control soil erosion

  • COVER methods.
  • Mulching.
  • Cover crops and green manures.
  • Green manures – also usually legumes – are planted specially to improve soil fertility by returning fresh leafy material to the soil.
  • Mixed cropping and inter-cropping.
  • Early planting.
  • Crop residues.
  • Agroforestry.

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 prevention of erosion?

Crop rows form hundreds of small dams that slow water and reduce soil loss up to 50 percent. Cover crops temporarily protect the soil until the main crop is planted. Cover crops also add organic matter and reduce weed growth. Plant cereal grains and legumes for winter cover crops.

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.

Is terracing 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.

What happens if terrace spacing is too less *?

Terrace spacing is decreased where rainfall amount and intensity are high and where the soil has a low infiltration rate, both of which produce high runoff rates. High runoff rates and steep slopes increase runoff erosivity and the potential for rill erosion.
