What are the disadvantages of contour farming
What are some 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 advantage and disadvantage 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 are the advantages of contour farming?
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.
What are advantages of contour plowing?
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 are the disadvantages of crop rotation?
Disadvantages of Crop Rotation
- It Involves Risk. …
- Improper Implementation Can Cause Much More Harm Than Good. …
- Obligatory Crop Diversification. …
- Requires More Knowledge and Skills. …
- The Difference in Growing conditions.
What do you mean by 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 contour farming reduces soil erosion?
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.
How does contour farming increase soil fertility?
Farming across the slope helps to shorten slope lengths, slowing down runoff water so it can soak into the soil. Contour farming slows water down and lets it soak into the soil. Combine contour farming with cover cropping and other conservation practices for more soil fertility and slope protection.
What are 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.
How crop productivity can be improved by contour farming?
The purpose of contour farming is to reduce runoff and soil erosion on mild slopes. This practice can also increase crop yield through the soil moisture retention in arid and semi-arid regions. Results showed contour cultivation reduced the annual runoff as 10% in compared with cultivation perpendicular to the slope.
Which of the following problem is best addressed with contour plowing?
Contour ploughing helps to reduce soil erosion.
What is the difference between contour farming and terracing?
What is the difference between contour ploughing and terrace farming? Contour ploughing is the ploughing, done at right angles to the hill slopes, ridges and furrows so that the elevation prevents soil erosion by wind and water. In terracing, wide steps are cut around the slopes of hills to prevent soil erosion.
What are the main factors that determine if a farmer should use contour farming?
Several factors influence the effectiveness of contour farming to reduce soil erosion. These factors include: 10-year, 24- hour rainfall in inches; ridge height; row grade; slope steepness; soil hydrologic group; cover and roughness; and slope length.
How is contour farming done?
What is the difference between contour farming and step farming?
Terrace farming and contour ploughing are both used to reduce soil erosion on slopes from tilled fields.
…

| 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. |

How is contour ploughing different from contour barriers?
What is the difference between contour barriers and contour Ploughing? Contour barriers are contour strips that intercept downslope flowing water and soil particles. Contour ploughing means following the natural contours when tilling the soil, planting and cultivating.
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 are the important feature of contour farming and terrace farming How are they helpful in soil conservation?
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 contour farming class 8?
Contour ploughing is a farming practice which involves ploughing the land along contour lines. It refers to planting across the slope rather than along it. The planting is done perpendicularly to the slope instead of being done in a parallel manner.
How much does contour farming cost?
The primary cost per acre for contour farming relates to the field layout and surveying of the contours. The cost for surveying varies from $5 to $10 per acre. Secondary costs for contour farming may include additional farming and harvesting costs for small row lengths in corners and ends of the field.
Who invented contour farming?
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.
What is contour farming class 5th?
Contour farming involves ploughing along contours in the form of steps which prevents direct flow of water down the slope thereby retaining water. It prevents soil erosion on hill slopes.
