Question

explanation of mulching , contour barriers, Rock Dam, terrace farming ,intercropping, contour ploughing and shelterbelts​

Answer 1

Answer:

• Mulching: Mulch is the process that any material spreading as a covering over the surface of soil. It is used to maintain soil moisture, suppress weeds, maintain the soil in a cool condition, and make it look more appealing to the garden bed.

• Contour barriers: Contour strips that intercept ‘water and soil particles’ flowing down slope. These obstacles are slowing down the movement of water and reduce its erosive force. They are also “filter out and trap” some of the soil particles that are suspended, preventing them from being washed off the field.

• Rock Dam: It is made by “bagged sand or gravel sand" or other durable material.  It is useful to reduce soil erosion in a drainage channel by limiting the channel flow velocity.

• Terrace farming: A terrace is a “piece of sloped plane” cut into a sequence of successively receding flat “surfaces or platforms”, similar to steps, for more efficient farming reasons.

• Intercropping: Intercropping is the practice of planting plants between row crops in order to maximize land use and to give competition to weeds that could otherwise use surplus water and nutrients.

• Contour ploughing: It is also referred to as Contour bunding is the farming “practice of plowing” and/or planting along a path following its contour lines of elevation.

• Shelterbelt: A planting that generally consists of one or more rows of trees or shrubs planted in a way that provides shelter from the wind and protects the soil against erosion. They are usually planted around the edges of farms in hedgerows.

Answer 2

Answer:

Explanation:

"Mulching: The process of covering the soil to support plant growth.

Contour barriers: These are barriers to slow down the movement of water down slope.

Rock Dam: A small dam constructed on a drainage way.

Terrace farming: Farming on receding surfaces resembling stairs.

Inter cropping: Growing different crops at a time.

Contour ploughing: Ploughing along the land contours to prevent soil erosion.

Shelter belts​: A line of shrubs planted to protect the crops from harsh weather."
