Answer 1

$\bold\pink{Question}$

List out any seven methods which can help in conservation of soil.

$\bold\red{Answer:-}$

Some methods of soil conservation are:-

1. $\bold\green{Mulching:-}$ The bare ground between plants is covered with a layer of organic matter like straw. It helps to retain soil moisture.

2. $\bold\green{Contour\:barriers:-}$ Stones, grass, soil are used to build barriers along contours. Trenches are made in front of the barriers to collect water.

3. $\bold\green{Rock\:dam:-}$ Rocks are piled up to slow down the flow of water. This prevents gullies and further soil loss.

4. $\bold\green{Terrace\:farming:-}$ Broad flat steps for terraces are made on the steep slopes so that flat surfaces are available to grow crops. They reduce surface runoff and soil erosion.

5. $\bold\green{Intercropping:-}$ Different crops are grown in alternate rows and are sown at different times to protect the soil from rain wash.

6. $\bold\green{Contour\:ploughing:-}$ Ploughing parallel to the contours of a hill slope to form a natural barrier for water to flow down the slope.

7. $\bold\green{Shelter\:belts:-}$ In the coastal and dry regions, rows of trees are planted to check the wind movement to protect soil cover.

Answer 2

Answer:

1. Practice No-Till farming

With no-till farming, crops are allowed to remain rather than being plowed under at the end of the season. This practice keeps soil anchored in place rather than having bare ground exposed to wind and water.

2. Use Terrace Farming

This type of farming uses the topography of the land to slow water flow through a series of terraces. This manipulation of the water flow prevents it from gathering speed and washing soil away from farmlands.

3. Practice Contour Farming

Contour farming replicates the effects of terrace farming, but on a smaller scale. Rather than planting crops in straight vertical rows, crops are planted following the contour of the landscape. Crops planted up and down hillsides create pathways for water to flow. Crops planted parallel to the land slow the flow of water that prevents soil erosion.

4. Reduce Impervious Surfaces

Impervious surfaces, such as driveways and patios, allow precipitation to flow freely over them. Water flow gains momentum when moving over such surfaces and can then erode stream banks and lakeshores. A good compromise is to use paving stones rather than a concrete slab for your patio to allow the water to percolate down into the soil.

5. Plant Windbreaks

Windbreaks prevent soil erosion by slowing the force of the wind over open ground. You can plant trees or shrubs in your windbreak. In addition to preventing erosion, these plantings will prevent snow from drifting onto your driveway or into the road. They can also protect your home from wind damage.

6. Restore Wetlands

Wetlands are one of the most effective ways to prevent soil erosion. Wetlands act as natural sponges, absorbing rainwater and preventing it from carrying the soil away. They also provide a habitat for birds and other wildlife and help prevent water pollution.

7. Plant Buffer Strips Along Stream Banks

Buffer strips help hold stream banks intact during times of flooding. They also prevent runoff from entering waterways. Buffer strips can include a mixture of grasses, shrubs, and trees.
