What is contour method in agriculture?
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 sustainable?
Contour farming captures twice the soil moisture and reduces soil erosion up to eight-fold. Above the “T” value means we are losing more soil than we are making which is not sustainable. We can calculate the annual average soil erosion rate by using a formula agronomists call the Revised Universal Soil Loss Equation.
Why do farmers use 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.
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.
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 are the benefits of contouring?
Whether surgical or non-surgical, facial contouring can provide patients with a rejuvenated appearance. Facial contouring can benefit a patient in need of surgery to reconstruct and reshape their face. It can also take years off a patient’s face, giving them that smooth and more youthful look they have been wanting.
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…
How contour Ploughing is done?
In contour plowing, the ruts made by the plow run perpendicular rather than parallel to the slopes, generally 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 are the disadvantages of contour plowing?
Drawbacks to contour plowing have caused it to be less widely used than conventional tillage methods. Some farmers may not have been fully aware of erosion damage and prevention. Lack of access to equipment, funding, or training sometimes take their toll.
What is the difference between contour Ploughing and contour barriers?
counter barriers:- Contour barriers are obstructions made on the slopes with the help of stones, grass, trenches in the soil to collect water. counter ploughing:- Contour ploughing is the farming practice of plowing and or planting across a slope following its elevation contour lines.
What is the difference between terracing and contour plowing?
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 is contour farming beneficial good for the soil?
Contour farming can also reduce soil erosion by as much as 50% compared to farming up and down hills, according the Natural Resources Conservation Service.
