Why is contour farming important?

Why is contour farming important?

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 the advantages and disadvantages 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.

What are the important features of contour farming and terrace farming How are they helpful in soil conservation?

Contour ploughing suits the slope’s natural shape without changing it. On the steep slopes, wide flat steps or terraces are designed so that flat surfaces are usable for cultivation, thus minimizing surface run-off and soil erosion.

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.

What are the advantages of contouring?

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.

Which of the following is the advantage of contour System?

Main advantages Contour ploughing prevents and mitigates the impacts of floods, storms and landslides in the cropping sub sector by reducing soil erosion up to 50%, controlling runoff water, and increasing moisture infiltration and retention thus enhancing soil quality and resilience.

How does contour farming help in the Soil Conservation Class 10?

Answer: 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 important features of contour farming and terrace farming How are they useful 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.

How does contour farming help in soil conservation?

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 does contour plowing reduce 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 help to prevent soil erosion?

What is the importance of terrace farming or contour bunding?

Answer: Terrace farming and contour ploughing are both used to reduce soil erosion on slopes from tilled fields. The differences between terrace farming and contour ploughing are tabulated below. Terrace farming shifts the slope’s structure to create flat areas that provide water catchment.

What is contour plowing and why is it important?

Contour plowing is the act of farming on a hill or a contoured area. The plow follows the contours of the land horizontally helping to reduce runoff of water. This practice helps to prevent soil erosion in hilly and contoured areas by capturing the water runoff using water breaks to keep water contained.

What is contour cultivation and how does it work?

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 lines in agriculture?

The contour lines contribute to improved water distribution in the crops. In addition, the contour lines decrease topsoil movement and avoid soil erosion. It is considered to be one of the method of sustainable agriculture. Was this answer helpful?
