What Is Contour Farming?

What is contour farming in simple words?

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 are the uses 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.

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 is 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.

Is contour farming bad?

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 is the advantages of Contour System?

Answer: The practice has been proved to reduce fertilizer loss, power and time consumption, and wear on machines, as well as to increase crop yields and reduce erosion. Contour farming can help absorb the impact of heavy rains, which in straight-line planting often wash away topsoil.

What does contouring mean?

1: an outline especially of a curving or irregular figure: shape the sleek contours of the car The map shows the contour of the coastline. also: the line representing this outline. 2: the general form or structure of something: characteristic —often used in plural the contours of a melody…

What is the meaning of contour barriers?

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 line?

Contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. Lines drawn closely together indicate that a slope is steep.

What are the method of contouring?

There are two methods of locating contours:

  1. Direct method.
  2. Indirect method.
  3. Direct method – In direct method contour to be plotted is actually traced on the ground.
  4. Procedure – The work is started from BM and the level is set up at the centre of the area.

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.

What is difference between contour barriers and terrace farming?

Terrace farming and contour ploughing are both used to reduce soil erosion on slopes from tilled fields. Write is the difference between terrace farming and contour ploughing.

Terrace farming Contour ploughing
Terrace 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 benefits of contour plowing?

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.
