Windbreak, alternatively known as Shelter-belt, is a method related to planting trees along agricultural fields in order to protect the soil from erosion from surrounding crops and to shelter them from the wind. It also helps the snow to slide in the pastures and cultivated lands, and is a good source of habitat for the local fauna. It can also be used to collect wooden products. The protection belt also provides a sort of safety barrier between the farm animals and the vehicles that are driven on nearby highways. It is also seen that if the windbreaks are carefully designed, it can reduce the cost of cooling and heating and is also used to save energy.
Importance of erosion control
Windbreaks play an important role in defending and controlling erosion, since the design of safety belts provides a means of protection for crops against wind speed and shelter both on the windward side and on the leeward side. The advantage of erosion control is that it helps to reduce wind speed or momentum, it provides armor to the ground surface to prevent soil particles from being raised. Protects agricultural fields and areas protected by seat belts. The other important role played by these seat belts is that the spacing for trees and shrubs on the ground helps reduce wind speed, helps increase crop yield by some 10% in the area, improvement is seen in ‘
Synthetic wind fences
Synthetic wind fences generally consist of canvas, cotton, recycled sails and nylon that can also act as windbreaks. They have three or more panels that are held in place with the help of poles that slide into the pockets that are sewn into the panels. This also helps reduce wind speeds on areas that have been eroded, such as open farms, dusty industrial operations and industrial stocks. They also reduce the amount of crashes and damage inside letting in smaller amounts of wind.
This term is used to refer to a combination of windbreaks and interlayer in sustainable agricultural practices. Called Alley Cropping, in this method the different crops are planted in distinct rows and are surrounded by the number of trees. This type of cultivation is successful in Africa, India and Brazil, where coffee farmers have particularly mixed agricultural and forestry practices. This agricultural crop is also grown along with a long-term crop of trees so as to contribute another source to farmers’ annual incomes. In the photo above, the corn is grown between rows of walnut trees in the United States.
Where are they used?
Windbreaks and safety belts are mainly used in areas that are field edges or trees are planted along the structures. If they are built correctly, then they are beneficial to wildlife and the people who live around the particular areas in which they are employed. They are also planted in exposed gardens where the wind speed is high and provide shelter even for large plantations.
