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.
What is the contour plowing technique?
Contour plowing furrows
run crosswise to the slope, slowing runoff and allowing the soil to absorb rainfall rather than wash away
. Contour plowing is usually employed along with strip cropping, that is, alternating different crops in narrow strips.
What is it called when you Plough across the slope of hills?
Contour bunding or contour farming or Contour ploughing
is the farming practice of plowing and/or planting across a slope following its elevation contour lines. … Contour ploughing helps to reduce soil erosion.
Which of the following techniques uses plowing across the slope to form ridges?
Contour plowing
was a method of plowing furrows that follow the curves of the land rather than straight up and down slopes. 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.
What is cross slope farming?
Cross-slope barriers are
measures on sloping lands in the form of earth or soil bunds, stone lines, and / or vegetative strips for reducing runoff velocity and soil loss
, thereby contributing to soil, water and nutrient conservation. This is achieved by reducing steepness and / or length of slope.
Why cultivation should be done across the slope?
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 can decelerate the flow of water down the slope?
Ploughing along the contour lines
can decelerate the flow of water down the slopes. This is called contour ploughing. … It implies that ploughing along contour lines can reduce the speed of water, flowing down as it creates a water break and allows water to settle down in the soil.
Is contour plowing good?
Contour farming can
reduce soil erosion by
as much as 50 percent compared to up and down hill farming. By reducing sediment and runoff and increasing water infiltration, contouring promotes better water quality.
Where is contour plowing used?
Contour plowing is normally used only
when the slope of the land is between 2 to 10% and when excessive rainfall is not generally a problem
. When these conditions are not met, strip cropping is used in addition to contour plowing to prevent problems from developing.
What is the difference between terracing and contour plowing?
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.
How can you prevent erosion on a steep slope?
Techniques for steep slopes include
wood retaining walls, interlocking concrete blocks, rock retaining walls
, riprap (loose rock) areas, and terracing. If you choose wood, make sure the wood is treated with a wood preservative to prevent rotting.
What are the methods of controlling erosion?
Among the top methods of soil erosion control are
reforestation, riprap, terracing, contour plowing and fencing
.
Which is strip farming?
Strip cropping is a
method of farming used when a slope is too steep or too long
, or otherwise, when one does not have an alternative method of preventing soil erosion. … The practice has been widespread in North America as a means of mitigating soil erosion from wind and water.
