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 the difference between Bund and terrace?
Bunds are simple earthen embankments of varying lengths and heights, constructed across the slope. … Bunds are
similar to the narrow based terrace
, but no agricultural practices are done on bunds except at some places, where some types of stabilization grasses are planted to protect the bund.
What is the difference between contour farming and terracing?
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 importance of terrace farming or contour bunding?
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 the difference between contour Ploughing and contour bunding?
This creates contour lines. Contour lines prevent tillage erosion and reduce the formation of gullies during heavy rainfall. Contour ploughing is a very effective soil erosion prevention technique. … Contour Bunding is a similar technique but has a wide range of applications besides farming.
What are the advantages of contour farming?
- Contouring can reduce soil erosion by as much as 50% from up and down hill farming.
- By reducing sediment and runoff, and increasing water infiltration, contouring promotes better water quality.
What is contour Ploughing in simple words?
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.
Which type of bunds are not suitable for clay soil?
The
contour bunds
are suitable for those areas, which receive the annual rainfall less than 600 mm. It is not suitable for clayey soils.
Which crop is most effective in controlling soil erosion?
| Excellent Very Good | Barley Annual Ryegrass | Cereal Rye Oat | Sorghum-Sudan Wheat | Cowpea Mustard |
|---|
What is contour Ploughing and its advantages?
Main advantages Contour ploughing
prevents and mitigates the impacts of floods, storms and landslides in the cropping sub sector
by reducing soil erosion up to 50%, controlling runoff water, and increasing moisture infiltration and retention thus enhancing soil quality and resilience.
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.
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.
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.
Where is contour farming used?
According to NRCS, contour farming is generally used on
sloping land where tillage, planting, and cultivation
are used to grow annual crops. In a properly designed contour farming system the tillage furrows intercept runoff and allow more moisture to infiltrate into the soil.
What is contour farming where and why it is done?
Contour farming, the
practice of tilling sloped land along lines of consistent elevation in order to conserve rainwater and to reduce soil losses from surface erosion
. … Contour farming can help absorb the impact of heavy rains, which in straight-line planting often wash away topsoil.
What are the types of contour farming?
- Mulch farming. Mulch is a layer of crop residue placed on the soil surface. …
- Conservation tillage. Soil structure is extremely prone to intense tropical rains and harsh climate. …
- Strip cropping. …
- Contour farming. …
- Cover crops. …
- Vegetative hedges or strips.
