How do terraces help conserve soil?

How do terraces help conserve soil?

Terraces reduce both the amount and velocity of water moving across the soil surface, which greatly reduces soil erosion. Terracing thus permits more intensive cropping than would otherwise be possible.

What is terrace farming How does terrace farming help in conserving soil?

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.

Why is soil important in rice terraces?

The terraces were built to make the most efficient use of shallow soil and to enable irrigation of crops by allowing runoff to occur through the outlet.

How was terrace farming helpful for farmers?

The Advantages Of Terrace Farming 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.

How do you maintain terraces?

Rehabilitate low spots by adding soil and reestablishing grass cover. Practice good tillage techniques in the future and avoid moving soil from the ridge of the terrace. Also check for excessive up slope erosion, which can lead to sediment deposits in the terrace channel.

What is the best way to 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 is the aim of 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.

Which type of farming is done on the hillside?

Hint:Step farming is also known as terrace farming. It is done by cutting steps in the hill slopes.

Where do terracing help the most in soil conservation *?

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

How can we save hilly land?

Avoid using off-road vehicles on hilly lands. Stay on designated trails….

  1. Reduce the amount of land that is logged and mined.
  2. Reduce the number of roads that are built to access logging areas.
  3. Avoid logging and mining on steep lands.
  4. Cut only small areas at one time and quickly replant logged areas with new seedlings.
