What is the difference between contour ploughing and terrace farming? … In terracing,
wide steps are cut around the slopes of hills to prevent soil erosion
. 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.
What is contour barriers in agriculture?
Contour barriers are
contour strips which intercept downslope flowing water and soil particles
. These barriers slow down the water movement and reduce its erosive force. They also filter out and trap many of the suspended soil particles, keeping them from being washed out of the field.
What is contour farming and terracing?
Furrows that run up and down a slope form a channel that can quickly carry away seeds and topsoil. Contour plowing forms ridges, slows the water flow and helps save precious topsoil. … Strip
cropping on
different levels (terracing) held water and stopped soil from washing away in heavy rain.
What is the difference between contour barriers and contour Ploughing?
Contour Bunding and Contour Ploughing are both forms of Sustainable agriculture. … Contour lines prevent tillage erosion and
reduce the formation of gullies during heavy rainfall
. Contour ploughing is a very effective soil erosion prevention technique.
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.
What are the disadvantages of contour farming?
Therefore, contour farming alone is not sufficient to control erosion on steep, long slopes, erodible soils, and during erosive rains. The major drawbacks of contour farming are
frequent turning involving extra labor and machinery time
, and loss of some area that may have to be put out of production.
What are the main features of contour farming?
Contour ploughing mitigates
the impacts of floods, storms and landslides on the crops
by reducing soil erosion up to 50 percent, controlling runoff water, increasing moisture infiltration and retention and thus enhancing soil quality and composition.
What are contour barriers made of?
To create barriers along contours,
stones, grass, soil
are being used. Trenches are made to collect water in front of the barriers. Rocks are stacked up to slow down water flow and also help to stop gullies and further erosion of soil.
What are contour lines?
A contour line is
a line drawn on a topographic map to indicate ground elevation or depression
. A contour interval is the vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line.
What do you mean by Contour Ploughing?
Contour plowing is
the act of farming on a hill or a contoured area
. … This practice helps to prevent soil erosion in hilly and contoured areas by capturing the water runoff using water breaks to keep water contained. Contour plowing is also known as contour farming, and is a sustainable form of agriculture.
What is meant by contour bunding?
Contour bunding (or contour bundling), which involves
the placement of lines of stones along the natural rises of a landscape, and contour farming
. These techniques help to capture and hold rainfall before it can become runoff.
How are contour lines drawn on maps?
Contour lines are lines drawn on a map
with equal elevation points
, so elevation would be constant if you followed the contour line physically. The elevation and terrain shape of the contour lines shows. It is useful because they show the form of the land surface on the map–its topography.
Is terrace farming 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
.
What is the benefit of terrace farming?
What are the benefits of a terrace system? The major benefit, of course, is
the conservation of soil and water
. 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 give example?
It is used to support growing crops that require irrigation, such as
rice
. Example: 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. Tea farmers also take advantage of terrace farming.
