What does contour mean?

What does contour mean?

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 pros and cons of contour plowing?

Disadvantages of Contour Plowing Some advantages of contour plowing is that it focuses on preserving topsoil by reducing erosion from water runoff. The major benefits of this methods is the preservation of the nutrients in the field, resulting in less fertilizer and less need for artificial irrigation. erosion.

What is the difference between contour plowing and terracing?

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.

Where is contour farming used?

Contour farming is a traditional Pacific Island practice that is very good for growing food on hillsides. When farmers carry out their farming activities (plowing, planting, cultivating, and harvesting) across the slope instead of up and down the slope, they are using contour farming contour farming contour farming.

What is called contour farming?

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.

How is contour farming done?

Contour farming involves ploughing, planting and weeding along the contour, i.e, across the slope rather than up and down. Contour lines are lines that run across a (hill) slope such that the line stays at the same height and does not run uphill or downhill.

What are the important features of contour farming?

In contour ploughing, the ruts made by the plow run perpendicular rather than parallel to slopes, generally resulting in furrows that curve around the land and are level. This method is also known for preventing tillage erosion. Tillage erosion is the soil movement and erosion by tilling a given plot of land.

What is the advantages of Contour System?

The advantages of contouring are: the velocity of runoff is checked; the adsorption of rainfall is increased; erosion is reduced by slowing the rate of runoff; and, temporarily storing runoff behind contour ridges increases infiltration and collects sediment.

Is contour planting good?

Contour farming captures twice the soil moisture and reduces soil erosion up to eight-fold. The simple act of planting across the slope instead of up and down the hill does two very important things: it captures at least twice the rainwater and reduces soil erosion up to eight-fold.

What are the advantages of contour farming?

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.

What is meant by Contour Ploughing?

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. A similar practice is contour bunding where stones are placed around the contours of slopes. Contour ploughing helps to reduce soil erosion.

What is the use of contour Ploughing Class 10?

Answer: Contour plowing is the process of farming by keeping the lines of contour on the sloppy regions. The contour lines contribute to improved water distribution in the crops. In addition, the contour lines decrease topsoil movement and avoid soil erosion.

What did farmers do to the land once they started plowing?

But for years, farmers had plowed the soil too fine, and they contributed to the creation of the Dust Bowl. The process pulverized hard dirt into small clods. In the early 30s, many farmers would come back into a plowed field with a set of disc harrows that would break the clods into fine soil particles.

What is contour Ploughing in simple words?

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.

Who uses contour plowing?

Contour plowing was first known to have been used by the Phoenicians in what is now Lebanon sometime during the period of 1200 to 900 BC. The practice slowly spread to many surrounding regions. It eventually reached Europe.

How does contour plowing conserve soil?

Answer: 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 is land contouring?

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. …

Does contour plowing cause desertification?

This can lead to large scale desertification which can permanently transform a formerly productive landscape to an arid one that becomes increasingly intensive and expensive to farm.

Why do farmers plow in circles?

Because the water falls directly on the crops instead of being shot into the air as occurs with traditional sprinklers, less water is lost to evaporation and more goes to nourishing the growing plants. Central pivot irrigation also creates perfectly circular fields, as seen in this image.

What is it called when you plow across the slope of hills?

What is it called when you plow across the slope of hills. Contour plowing. Which soil conservation technique prevents erosion on steep hills by heavy rains.

How does no till farming work?

No-till farmers grow crops with minimal disturbance to their fields and the organisms that call them home. This builds healthier soils while reducing money spent on fuel and labor – a win-win. With harvest season winding down, you’re no doubt making an important decision for your working land.
