What is contour plowing quizlet?

What is contour plowing quizlet?

Contour Plowing. An agricultural technique in which plowing and harvesting are done parallel to the topographic contours of the land, in order to prevent erosion.

How does the contour plowing technique conserve soil?

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 long has contour plowing been practiced?

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.

Does contour plowing prevent soil erosion?

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 is the slash and burn method?

Slash-and-burn agriculture, method of cultivation in which forests are burned and cleared for planting. Traditionally, the area was left fallow and reverted to a secondary forest of bush. Cultivation would then shift to a new plot.

Why is slash and burn farming sustainable?

Slash-and-burn agroecosystems are important to rural poor and indigenous peoples in the developing world. Ecologically sound slash-and-burn agriculture is sustainable because it does not depend upon outside inputs based on fossil energy for fertilizers, pesticides and irrigation.

Is contour plowing a sustainable development?

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.

Where is contour Ploughing practiced?

Contour ploughing is a soil conservation technology that is practiced throughout Grenada to mitigate the negative consequences of natural disasters on soil quality and composition.

Where is double cropping possible?

Viewed as shares of each region’s total cropland, double cropping was most common in the Northeast, Southeast, and Southwest regions.

Which is the best description of contour plowing?

Contour plowing or contour farming or Contour ploughing is the farming practice of plowing and/or planting across a slope following its elevation contour lines.

What are the different methods of contour farming?

Some of the methods used to date include windbreaks, planting cover crops, planting grass on waterways, and contour cultivation among others. Contour cultivation (contour farming, contour plowing, or contour bunding) is a sustainable way of farming where farmers plant crops across or perpendicular to slopes to follow the contours of a slope …

What is the meaning of contour bunding in farming?

“Contour bunding”, Catalonia, 2007. 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.

Why are contour lines important for soil erosion?

These contour lines create a water break which reduces the formation of rills and gullies during times of heavy water run-off; which is a major cause of soil erosion. The water break also allows more time for the water to settle into the soil.

Is contour plowing also known as no-till plowing?

The practice of plowing fields along the curves of a slope is called contour plowing. User: Contour plowing is also known as no-till plowing. Weegy: Contour plowing is also known as no-till plowing.

What are the disadvantages of contour farming?

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 does contour plowing do for fields?

Contour cultivation (contour farming, contour plowing, or contour bunding) is a sustainable way of farming where farmers plant crops across or perpendicular to slopes to follow the contours of a slope of a field. This arrangement of plants breaks up the flow of water and makes it harder for soil erosion to occur.

What is the importance of contour farming?

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. The agency also notes that because contour farming reduces water runoff, it controls the amount of twigs, pebbles, sand, and other debris, resulting in better water quality.
