What is terracing? Terraces are earthen structures that intercept runoff on moderate to steep slopes. They transform long slopes into a series of shorter slopes. Terraces reduce the rate of runoff and allow soil particles to settle out. The resulting cleaner water is then carried off the field in a non-erosive manner.
What is agricultural terracing?
In agriculture, a terrace is a piece of sloped plane that has been cut into a series of successively receding flat surfaces or platforms, which resemble steps, for the purposes of more effective farming. This type of landscaping is therefore called terracing.
What are the types of terracing?
There are three kinds of terraces (a) bench terraced farmlands; (b) sloping terraced farmland; (c) combination level terraced farmlands and natural slope land. Bench terrace is the basic type of farmland in mountains.
What is terracing in soil conservation?
Terracing is the practice of creating nearly level areas in a hillside area. The terraces form a series of steps each at a higher level than the previous. Terraces are protected from erosion by other soil barriers. Terraced farming is more common on small farms.What is an example of terracing?
Perhaps the most well-known use of terrace farming are the rice paddies of Asia. Rice needs a lot of water, and a flat area that can be flooded is best. … Terrace farming is used for rice, barley and wheat in east and southeast Asia and is a key part of the agricultural system.
Why is terracing an important farming techniques?
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 terracing in geography?
A terrace is a raised portion of land that is flat or nearly flat and level above a shoreline, valley, or plain.
How is terracing done?
Terrace farming is a technique of farming whereby “steps” known as terraces are built onto the slopes of hills and mountains. Whenever it rains, instead of rain carrying away the soil nutrients and plants down the slope, they flow to the next terrace. Every step has an outlet that channels the water to the next step.What is the difference between contour Ploughing and terracing?
Contour ploughing is the ploughing, done at right angles to the hill slopes, ridges and furrows so that the elevation prevents soil erosion by wind and water. … Terrace farming alters the shape of the slope to produce flat areas whereas contour ploughing follows the natural shape of the slope without altering it.
How does terracing lead to sustainability?Terraces provide multiple ecosystem services that can be summarized as follows: (i) runoff reduction, water conservation, erosion control and increase of soil conservation, enhancement of biodiversity; (ii) carbon sequestration, enhancement of soil fertility and land productivity, increase of crop yield and food …
Article first time published onIs terracing of slopes a soil conservation method?
Question : Terracing is an effective method of soil conservation in. by Biology experts to help you in doubts & scoring excellent marks in Class 11 exams. Terracing farming is a widely practicised in hilly area in which slope is divided into a number of flat field for slowing down the flow of water.
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.
Where is terrace farming done in India?
Terrace farming is practised mainly in hilly areas. In India, it is practised in hilly areas mainly like Himachal Pradesh, Uttarakhand and some northeast states. It is also practised in South area, like Andhra Pradesh.
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.
Why do rivers form terrace?
When rivers flood, sediment deposits in sheets across the floodplain and build up over time. Later, during a time of river erosion, this sediment is cut into, or incised, by the river and flushed downstream. The previous floodplain is therefore abandoned and becomes a river terrace.
What is a terrace building?
A terrace is an external, raised, open, flat area in either a landscape (such as a park or garden) near a building, or as a roof terrace on a flat roof.
What does terrace farming look like?
Terrace farming is a method of farming whereby “steps” known as terraces are built onto the slopes of hills and mountains. When it rains, instead of rain carrying away the soil nutrients and plants down the slope, they flow to the next terrace. Every step has an outlet which channels water to the next step.
What is the main problem with terrace farming?
The challenges of terrace agriculture in these regions include lack of quality land area for agriculture, erosion and loss of soil fertility, low yield, poor access to agricultural inputs and services, lack of mechanization, labor shortages, poverty, and illiteracy.
How does terracing help in water conservation?
By reducing surface runoff which ensures that rainwater seeps slowly into the ground.
What is contour and terracing method?
Contour farming is the farming practice that involves the ridge making across the slope of the land but Terracing is an engineering aspect of erosion control that involves the construction of short steps along the contours of the land with a view to preventing the rapid flow of water down the slope.
What is the difference between terrace farming and terrace cultivation?
Terrace farmingContour ploughingTerrace farming shifts the slope’s structure to create flat areas that provide water catchment.Contour ploughing suits the slope’s natural shape without changing it.
What are the main difference between Terrace and Bunds?
Terraces usually follow the contour lines of a terrain and might have a gentle slope to allow dewatering. Contour bunds and contour trenches prevent soil erosion by intercepting surface water runoff. They are constructed along lines of equal elevation (contour lines) at a right angle to the slope of a plot of land.
What kind of crops are grown in terrace farming?
Paddy, cereals, berries, vegetables, flowers, medicinal plants, aromatic plants, colouring plants, wheat, maize, rice, pulses, oilseeds, millets, buckwheat, saffron, black cumin, grain amaranth, spices, etc. are some crops grown using terrace farming.
How do I start terrace farming?

Where is terrace farming practiced?
Terrace farming is practised mainly in hilly areas. It is practised in hilly areas in India, mainly like Himachal Pradesh, Uttarakhand, and some northeast states. It is also practised in the Southern areas, like Andhra Pradesh.
How does terracing prevent erosion especially in steep areas?
Terraces divide slopes so that surface runoff is intercepted and carried to a protective outlet. Terraces decrease erosion by shortening slope length, slowing runoff velocity, and trapping sediments. Runoff water concentrates in waterways that when bare or unstable are extremely erodible.
What is terrace slope?
In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a “riser” or “scarp”. … Terraces are formed in various ways.
What is terrace farming How does it prevent soil erosion?
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 do we need terrace garden?
Reduce overall heat absorption of buildings and insulate the building against heat and cold. Convenience of safe, pesticide-free, healthy green and fresh vegetables. Conducive to a routine of physical exercise, clean air and being close to nature. Increases amount of oxygen in the air.
