Soil conservation is the practice of protecting soil from degradation, erosion, and depletion. It is important for maintaining the health and fertility of the soil, as well as for preserving the natural environment and biodiversity. There are several methods of soil conservation, which can be broadly classified into three categories: physical, chemical, and biological methods.
Physical methods of soil conservation involve protecting the soil from erosion and other physical degradation. One common physical method is the use of terracing, which involves the construction of raised beds on sloped land. This helps to reduce the impact of erosion by slowing down the flow of water, and also allows for better water retention in the soil. Another physical method is the use of windbreaks, which are rows of trees or other vegetation that are planted along the edge of fields to reduce the impact of wind erosion.
Chemical methods of soil conservation involve the use of chemical agents to improve the physical and chemical properties of the soil. One example of a chemical method is the use of fertilizers, which can be used to add nutrients to the soil and improve its fertility. Another example is the use of lime, which can be used to adjust the pH of the soil and make it more suitable for certain crops.
Biological methods of soil conservation involve the use of living organisms to improve the health and fertility of the soil. One example of a biological method is the use of cover crops, which are planted between main crops to provide organic matter to the soil, reduce erosion, and suppress weeds. Another example is the use of crop rotation, which involves growing a variety of crops in a field over time, rather than growing the same crop every year. This helps to maintain the fertility of the soil and prevent the build-up of pests and diseases.
In addition to these specific methods, there are also more general practices that can help to conserve soil. These include reducing soil disturbance, such as by using no-till farming techniques, and promoting the use of sustainable farming practices, such as using organic fertilizers and pesticides.
Overall, soil conservation is an important aspect of sustainable agriculture and land management. By using a combination of physical, chemical, and biological methods, we can protect the health and fertility of the soil, and ensure that it is able to support healthy crops and ecosystems for generations to come.
Soil Conservation Methods
Water is channeled slower along the vegetated channel to a safe, stable outlet such as a grassed waterway or standpipe or drop inlet. Accessed 17 May 2022. The strategies involve alleviating the effects of soil erosion and improving overall fertility by minimizing soil degradation and soil pollution by integrating new age food technology and science with proper pest- and weed-control methods. Maintaining PH levels of soil Contamination of soils due to acid rains and other pollutants can lead to loss of soil fertility. The roots of these plants fix the soil to avoid slumping and erosion, canopies protect from excessive sunlight to water inhabitants and falling leaves are a source of organic matter and food to minor aquatic animals. Terracing then Contour Bunding Terracing and structure bunding throughout the slope inclines are an extremely Herculean and perhaps the almost seasoned strategy for base preservation. It is connected to a ditch, pit, or current to collect water, and the grassroots keep the earth in place, protecting it from water erosion, and thus contributing to soil conservation.
Soil conservation methods target long-term use with a thought of the future. The clean water is then taken off the surface and guided to an appropriate outlet to a stream or ditch. Evergreen trees can provide year-round protection, but 6. Elimination of nitrogen fertilizer and fungicides can also increase the yield and protect the crop from drought and flooding. For this reason they are also referred to as nitrogen fixing plants.
What are methods of soil conservation? ~ Geography Notes for UPSC , State PCS Exam, and NCERT Classes
Organic matter is what provides good soil structure and water holding capacity, promotes water infiltration, and protects the soil from erosion and compaction. The main principles are: a to keep bare soil protected at ll time of the year either with living vegetation, or with residue from the previous crop; and b to minimize the number of times the field is tilled. So, what is soil conservation? Chapter - 2 Land-Soil-Water-Natural Vegetation and Wildlife Resources, Cass 8 NCERT Resources and Development Geography Answer. Fields about a slant greater extreme than 15% or 1 out of 6 obligations in conformity with being removed out of furrowing so those are now not commonly worth the labor on construction seats fantastically near one another. Holding dividers of porches monitoring the development over lotos or aid in decreasing along ruining disintegration.
Soil Conservation: Methods, Types, and Importance Free Essay Example
Established in the year 2011 are recognized as a reputed firm that is enraged in manufacturing of a wide range of agricultural soil-conditioners which are used to rebuild the soil quality which have been damaged by improper management. This can be prevented by constructing walls or planting useful tree species along the stream banks. The system looks like a set of steps. The method is most effective against wind erosion, and is most needed in sloping areas of land. Ther first two methods use loose rock to break the impact of stream water on the bank, and to protect the underlying loose soil surface. Among them include, preventing the fertile soil from getting washed away by the rainwater that flows down the land.
Soil Conservation Definition, Principles, and Methods Explained
Another benefit of strip cropping is the organic matter added from the forage or cereal crop rows. Maintenance of Ph levels in Soil If the soil becomes excessively acidic due to acid rain and other pollutants, it may lead to loss of soil fertility. Natural vegetation, particularly trees, grow roots deep into the subsoil. The Soil Microorganisms Besides the earthworms that are a real savior for the soil, there are several good microorganisms in the soil that keep it healthy. Drop inlets and rock chutes are often used to step water down where there are rapid elevation changes, thereby protecting soil from erosion.
List Out Three Methods Of Soil Conservation Q&A BYJU'S
Dry Fanning: This method is useful for the cropland existing in the areas of lower moderate rainfall. Soil conservation is an essential part of sustainable agriculture. They should be protected from tillage, machinery and cattle access to work effectively. Drop inlets and rock chutes are often used to "step" water down where there are rapid changes in elevation, and thereby protect soil from erosion. This enhanced federal contribution to the matter. Conservation tillage also enhances wildlife habitat for soil organisms, birds and small animals like field mice and snakes.
This blog will help in the spreading of knowledge about soil conservation. When these worms excrete egesta, this sits in the soils and gives the crops many nutrients which are absorbed via the roots of the plants. Crop rotations: Alternatively growing a cereal and a legume in the same field will not only increase the yield, but also increase the fertility of the soil. What are the various methods of land conservation class 10? Afforestation, land reclamation, regulated use of chemical pesticide and fertilisers and checks on overgrazing are some of the common methods used to conserve land resources. Advances in Agriculture 2021 2. Soil conservation is fundamentally a matter of determining a correct form of land use and management.
