Trenches are also made to collect water and prevent it from running off with soil. Accent Vegetation There are certain types of vegetation that acts as an accent to the planting process. It will be almost impossible to support the animal and human life without land. The improved dry farming practice developed as result of researches carried out in India is an integrated rational system of cultivation of purely rained and drought enduring crops in dry areas. Soil-conserving tillage practices conservation tillage and no-till combined now represents over 80% of Canadian cropland. It will take hundreds of years to form an inch of soil, but in no time it gets washed away down the slope due to erosion.
Political and economic action is further required to solve the erosion problem. The guidelines provide for rights to usufruct and non-wood forest products and percentage share of final harvest to organized communities willing to help regenerate depleted forest and waste lands. Maintaining the correct value of soil pH, is thus essential for soil conservation. Hence treatment measures on watershed basis from top to bottom down to the drainage line are taken up under watershed development programme with active participation of the people of the locality. Strip cropping: This is an agricultural practice of growing plants in suitable strips in the field. In this process, the excavated soil is deposited along the lower edge of channel in the form of low ridge. When plants, especially trees, die, they decay and become part of the soil.
This means planting foliage in forest undergrowth areas. If one crop fails due to diseases or any other factor, the others remain ensured. Fewer Concrete Surfaces Soil requires an adequate amount of water in order to function properly. If the answer is negative, it is high time we adopt the method of watering soil as a measure of conserving soil. Its value makes its conservation very important.
Disposal of Hazardous Chemicals You need to correctly by recycling them or taking them to a hazardous waste disposal site. Your lawn only needs about 1 inch of water per week. Eliminating the use of nitrogen fertilizer and fungicides can increase yields and protect crops from drought and flooding. Plants plant foods are at the base of a food pyramid and are crucial to the existence of life. Afforestation is the best means to check the soil erosion. At the same time, there may be lasting damage to the soil itself.
Terracing may be of the following four types: a Channel terracing: This is concerned with making of wide but shallow channels on contours at suitable distance. There are methods that can protect and conserve our soil at the same time. There is also a campaign by local groups to educate villagers to claim and manage forest areas, which have been monopolized for long. If the answer is negative, it is high time we adopt the method of watering soil as a measure of conserving soil. Steps are formed by the terraces which are surrounded by a mud wall to prevent run off and hold the soil nutrients in the beds.
Clover and rye are two examples of these accents. Contour farming: Crops are cultivated along the contour of the land. There are a few types of contour farming including terracing. Moreover, the share of land at risk to salinisation has also decreased over this period. Soil conservation is the prevention of soil loss from erosion or reduced fertility caused by over usage, , salinization or other chemical soil contamination. Sometimes tree crops such as rubber are also planted to combat soil erosion Fig. Monitor Grazing Farmers in different industries can play a critical role to conserving soil.
Soil pH is an indicator of the level of nutrients in soil. The ridges reduce the flow of water. Excessive deposition of salts in the soil makes it unsuitable for plant growth. Shifting cultivation on the hill slopes, non-adoption of soil conservation techniques, and over exploitation of land for crop production due to population stress, leads to enormous soil erosion. Soil erosion by wind can be checked or reduced if the soil is covered by vegetation. Agronomic practices: Normally, the land will possess a vegetational cover so as to prevent erosion. Reforestation means replanting of forests at places where they have been destroyed by uncontrolled forest fires, excessive felling and lopping.
What we have done to take care of our environment has manifested in so many ways, just like the disasters we have encountered in the past or the tragedies our ancestors and elderly have gone through. Flooding of rivers has been the cause for many instances of soil erosion. Contour ploughing also helps in the percolation of water into the soil. On the windward side Leptadenia spartium, Cenchrus ciliaris, Balanites roxburghii, Calligonum polygonoides, Sachharum munja, Kochia indica, etc. To reduce the velocity of run-off water and to retain it for long period so as to allow maximum water to be absorbed and held in the soil. . Important dry farming regions of India are: 1 Punjab, 2 Rajasthan, 3 South-west part of U.
Soil management that returns plant nutrients to the soil at the rate of their removal by crops will help maintain soil fertility. Biological Methods Under biological soil conservation methods there are three well known practices that can be even further divided. Individuals may opt to find a less harmful way to till the soil. Terracing A terrace is an embankment of ridge of earth constructed across the slope to control run off and to minimize soil erosion. They also help in checking soil erosion. This prevents the chemicals from contaminating the soil. Practicing overall is another idea and successful method.
