Terracing and Contour Bunding

Terracing and contour bunding are soil conservation techniques primarily used to prevent soil erosion, especially on sloping lands.

Strip terraces are not a common type of terrace used in agriculture. The other options, bench terrace, contour terrace, and broad-base terrace, are widely used.

Contour bunds are primarily used to reduce runoff velocity and prevent soil erosion by slowing down the flow of water.

Terracing and contour bunding are crucial in areas with steep slopes to prevent soil erosion and conserve soil moisture.

Terracing and contour bunding primarily focus on soil conservation and water management. While they can indirectly contribute to improved soil fertility, it is not their primary benefit.

The spacing between terraces is primarily determined by the slope of the land. Steeper slopes require closer spacing to effectively control erosion.

Contour bunding is generally recommended for slopes ranging from 5% to 10%. Steeper slopes may require additional soil conservation measures.

Terracing and contour bunding can improve water infiltration and soil moisture retention, which is a benefit, not a disadvantage.

Vegetative contour bunds are primarily used to trap sediment and prevent erosion by slowing down the flow of water and promoting vegetation growth.

Potatoes are not typically grown using contour farming techniques. Rice, wheat, and corn are commonly cultivated using contour farming methods.

The height of contour bunds is primarily determined by the rainfall intensity in the area. Higher rainfall intensity requires taller bunds to effectively control runoff.

Contour farming primarily focuses on soil conservation and water management. While it can indirectly contribute to improved soil fertility, it is not its primary benefit.

The recommended spacing between contour bunds is typically 4-5 meters. This spacing allows for effective control of runoff and soil erosion.

Sandy soils are not typically suitable for terracing and contour bunding due to their low water-holding capacity and susceptibility to wind erosion.

Contour strip cropping is primarily used to reduce runoff velocity and prevent soil erosion by alternating strips of different crops along the contour lines.
