This also reduces wind velocity and protects the topsoil from erosion.As educators, we should always be striving to help our students understand that the skills we are teaching are them are FOREVER…not just to complete a math page or worksheet. ![]() ![]() Ploughing the land in a perpendicular direction to wind direction. (viii) Ploughing the Land in Right Direction: The new method involves the provision of agricultural implements, residential accommodation. Arrangements for tribal resettlement can help to make them understand the new way of cultivation. We can persuade tribals to switch over to settled agriculture by checking shifting cultivation. Shifting cultivation method is mainly used by tribal. It is done by cutting hill slope into a number of terraces having horizontal top and steep slopes on the back and front. Terracing and contour bunding across the hill slopes are very effective. It is likely to develop and reduce run-off so that plants receive more water.Ĭlaims to be one of the oldest methods of soil conservation. As gullies are less, this prevents excessive soil loss. It makes the ridges and furrows break the flow of water down the hill. Ploughing is done at right angles to the hill slope, following the natural contours of the hill. In this way it can help in reducing the soil erosion. Thus putting lesser pressure on the soil. Primary budding varieties of crops take really very less time to mature. This very method gives surety that at no time of the year the entire area is left bare or exposed. Numerous yields ripen at diverse times of the year and are harvested at intervals. Some strips may be allowed to lie fallow while in others different crops may be sown e.g., small tree crops, grains, grass legumes, etc. Parallel to one another, crops may be cultivated in alternate strips. This practice takes away certain elements from the soil, making it infertile and exhausted rendering it unsuitable for that crop. In India, peasants grow a particular crop in the same field year after year. Roughly the context is described below:Īs the name suggests, it is rotating crops. We can save a lot of our valuable soil by bringing about certain changes in our agricultural practices. Water speed can be checked and it considerably saves soil from erosion. Soil erosion which happens maximum by river floods can be avoided by constructing dams across the rivers. One of the scientific methods to check soil erosion. Alternate fodder crops should be grown in larger quantities. One can earmark separate grazing grounds. ![]() But overgrazing of forests and grasslands by animals, especially by herds and flocks of sheep, goats, should be properly checked. Nevertheless, it was raised to 33 per cent in the second five-year plan the proportion being 20 per cent for the plains and 60 per cent for hilly and mountainous regions. 20 to 25 per cent, as they say, is the minimum area of forest land for the whole country which is considered healthy for soil and water conservation. Undiscriminating trees cutting should be stopped and efforts should be made to plant trees in new areas. One of the best ways to conserve soil is to increase the area under forests. In our country, soil erosion has been continuing over for such a long time that it has assumed alarming proportions.įollowing methods are normally adopted for conserving soil: All those measures that include help in protecting the earth from destruction and exhaustion are known as soil conservation. ![]()
