difference between afforestation and conservation of soil
Answers
Answer:
planting of tress is called afforestation.
protection the soil from erosion by adopting various method.
Answer:
The afforestation and soil conservation are two different terms but they are closely related with each other when it comes for the protection of soil and plants. If we define afforestation in simple terms we can say that it is the establishment of the forest or a stand of tree in an area where there was no previous tree cover. Coming to the soil conservation we will define soil as a unconsolidated mineral or organic material on the immediate surface on the earth that serves as a natural medium for the growth of land plants. As we all know that soils are essential for the continuity of life on the earth since many ecosystems depends on them for survival. Still, soils persist to face serious threats in so many ways i.e, soil erosion, use of chemical pesticides, excessive farming, water pollution and land pollution are some of the aspects that are upsetting the natural function of the soil. This is where soil conservation comes in.
Soil conservation is the practice of protecting the soil against erosion or deterioration. It means, to prevent the soil loss from erosion or reduce fertility caused by over usage, acidification, salinization or other chemical contamination. Soil conservation involves the activities that can be undertaken to ensure the soils are at their optimum quality and health. It is a methodology to maintain the soil fertility, prevent soil erosion and exhaustion and improve the degraded condition of the soil.
Both the term “Afforestation and soil conservation” are directly and indirectly linked with the protection of soil. Directly in the sense through cover crops, wind break, terrace farming, contour plowing, green manures, mineralization, dry faming, rain gardens, re establishment of forest covers, indigenous crops, prevent over grazing or indirectly by aforestation. As we are probably aware, the underlying foundation of the trees holds the dirt layer firmly, it is obvious that it encourages not making the dirt free and anticipates disintegration. Therefore, by planting increasing tree, the top layer of the dirt turns out to less incline to disintegration by wind, water, anything likely. Thus it averts disintegration and aids in the soil preservation and conservation.
Importance of Soil Conservation
Most of us have probably realized it by now that soil is necessary for the sustainability of human kind. It might sound a little cliché. Yet what we sow is what we harvest. While we have started some precautionary and conservation measures, here are few reasons why soil protection is imperative:
The soil is literally the foundations of plant life. A tree will not be a tree without soil. While there are some plants that can leave in water or air, most plants need to be rooted to the ground. It is the soil that provides nutrition to this plant life. It is through this vegetation that nourishes the human kind and animal kingdom.
The soil additional support the animal kingdom:- It will be almost impossible to support the human life without land. Biodiversity relies on soil at all times.
The soil is necessary for water supply:- The land is necessary ensure the quality of water that we derive from our earth. Soil and water co exist. Taking good care of our soil equates to taking care of water supply.
The protection of natural and agriculture land as link to a sustainable economy and healthy communities. In addition, conservation land and ecosystem services they provide are just as important to our economy and well being as are our roads residents and small businesses etc. Natural and agriculture lands are vital for water quality and supply, our wildlife and our tourism. This land supports us they provide pure and clean water, provide flood control, storm protection, food, recreation, clean air etc. Soil conservation is not an amenity value; it is vital for our future. As we think about the world around us and how it changed over the years, during most of our lifetime, we have seen large changes in the environment around us. We may have seen forest to cut down for housing or farm field to be turned in to a shopping centre. All though some of these changes are necessary for human survival, as we convert more and more natural land to develop land, there is a growing concern over the amount and quality of the natural land that remains.
