Answer:

Answer: Preventive methods of soil erosion (i) Afforestation Planting more trees reduces soil erosion. (ii) Contour Ploughing Ploughing land in furrows across the natural slope of the land helps trap water and prevent the washing away of top soil along with it.

Answer:

You can reduce soil erosion by:

• Maintaining a healthy, perennial plant cover.

Mulching.

• Planting a cover crop – such as winter rye in vegetable gardens. Includes annual grasses, small grains, legumes and other types of vegetation planted to provide a temporary vegetative cover. Cover crops are often tilled under serving also as a “green manure” crop.

• Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

• Using other erosion controls that include the use of geo-textile materials or other methods such as sodding or hydroseeding that result in the establishment of permanent cover.

• These methods work well on steep slopes and heavy traffic areas. Contact your local landscape contractor or the RI Nursery and Landscape Association.

• Addressing problem areas of that get lots of stormwater runoff.

• Solutions to these problem areas include redirecting stormwater and roof runoff to areas that can settle and dissipate water, such as a rain garden.
