What is contour plowing?
Contour plowing follows the contours of hills and slopes, rather than orienting crop rows up and down a slope. Contour plowing furrows run crosswise to the slope, slowing runoff and allowing the soil to absorb rainfall rather than wash away.
What does conservation plowing mean?
Conservation Tillage/Plowing: Conservation tillage is a method used by farmers to reduce soil erosion between crop harvesting and next crop planting. It involves leaving the stalks/residuals of the previously harvested crop in place.
What is an effect 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.
How do you do contour Ploughing?
Contour ploughing should be used on steep slope areas. The land is ploughed perpendicular to the slope, alongside contour lines that curve around the arable land. Contour lines favor infiltration of rainwater as water run-off is stopped.
What is contour plowing and terracing?
Contour plowing forms ridges, slows the water flow and helps save precious topsoil. Strip cropping on different levels (terracing) held water and stopped soil from washing away in heavy rain.
What is contouring in farming?
Contour farming is the practice of tillage, planting, and other farming operations performed on or near the contour of the field slope. Tillage and planting operations follow the contour line to promote positive row drainage and reduce ponding.
What is contour erosion?
What it is. Contouring means farming with row patterns nearly level around a hill – not up and down hill. The rows form hundreds of small dams that slow water flow and increase infiltration to reduce erosion.
What is contour Ploughing 10 CBSE?
Answer: Contour plowing is the process of farming by keeping the lines of contour on the sloppy regions. In addition, the contour lines decrease topsoil movement and avoid soil erosion. It is considered to be one of the method of sustainable agriculture.
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 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 is a disadvantage 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.
How are contour lines drawn on maps?
Contour lines are lines drawn on a map with equal elevation points, so elevation would be constant if you followed the contour line physically. The elevation and terrain shape of the contour lines shows. It is useful because they show the form of the land surface on the map–its topography.
What are the advantages 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.
Is contour plowing 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.
How does contour plowing conserve soil?
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. Strip cropping on different levels (terracing) held water and stopped soil from washing away in heavy rain.
What is contour system?
Contour farming is a technology, a practice, or a system in sloping agricultural lands whereby crop rows are oriented perpendicular to or across the slope of the land. Both in short-maturing annual crops, e.g., corn, and in perennial crops, e.g., coconut, the same rule applies.
What is contour method?
The contour method determines residual stress by cutting a specimen into two pieces and measuring surface height maps, or contours, on the free surfaces created by the cut. The result is a 2-D map of residual stress normal to the measurement plane.
What is an example of contour farming?
Contour farming is farming with row patterns that run nearly level around the hill — not up and down the hill. Contour stripcropping is crop rotation and contouring combined in equal-width strips of corn or soybeans planted on the contour and alternated with strips of oats, grasses, or legumes.
What is contour ridging?
Contour ridges, sometimes called contour furrows or micro watersheds, are used for crop production. Ridges follow the contour at a spacing of usually 1 to 2 metres. Runoff is collected from the uncultivated strip between ridges and stored in a furrow just above the ridges. Crops are planted on both sides of the furrow.
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.
