Soil is a living and life-giving natural resource that promotes plant growth, makes a habitat for living things, and stores water. The water in the first cut is really dirty, the water from the second and third cups are much cleaner which shows that both mulch as well as the root structure of plants assist in preventing soil erosion. (3) Soil erosion. Shape the soil into a mound at one end of the container. Soil Erosion Caused by Water: Removal of soil from one part to another usually down hill, by the action of water is known as water erosion. Soil erosion is a natural process. Plants have extensive root systems that can help "grab on" to soil and keep the soil clumped together. Without a healthy plant and soil ecosystem soil and the land in general can degrade and become inhabitable. Dependent Variable: The amount of erosion that occurs, measured in water clarity. These results indicate that the sum of plant importance values increased from 260.72 to 283.06, species density increased from 2.5 to 4.5 per m 2 , and the amount of litter and humus increased from 24.50 to 605.00 g/m 2 during the . This layer of soil can be heavily eroded by the wind, rain and human impacts. The soil is put into the Plexiglas cube and allowed to settle. Water is a critical element for plant growth. Soil erosion: An agricultural production challenge. Erosion Experiment. The water quality in nearby bodies of water would indicate how much erosion occurred, as well as measuring whether the height of the soil increases or decreases. Next, make similar structures with dry soil and dry sand, for a total of four structures: one made from muddy soil, one dry soil, one wet sand, and one dry sand. This will hold the soil. A few ice cubes. Sheet Erosion: In this case, flowing water remove soil from large areas in form of sheet. Soil Erosion 2. This these conclusions are derived from a four-year experiment without confirms that sediment yield is typically lower than gross erosion exceptional events; (2) the differences in soil texture, size and within the catchment (Walling, 1983) and that a catchment soil slope of the two experimental fields may partially explain loss cannot be . This water erosion experiment for kids is a fun science activity that is easy to do in any classroom. This happens naturally, but humans are speeding the process up, upsetting the balance in our ecosystems. Soil Erosion Caused by Water: Removal of soil from one part to another usually down hill, by the action of water is known as water erosion. It can lead to soil structure destruction and nutrient loss, causing the degradation of soil functions and reductions in crop yield [].Soil erosion also plays an important role in affecting hydrological process and cycling of crucial elements, such as carbon and nitrogen [2,3].A report released by the Food and Agriculture Organization (FAO) of . Soil and rocks may be detached and moved by natural erosion (water, wind, ice or gravity) or by human activity (removal of vegetation, agriculture, and urbanization). Now that your creations exist, it's time to see which stand up to wind and water. Information backing up that the grass covered soil is the best way to prevent soil erosion, and the results of this experiment, is discussed in an article from the nytimes.com. Soil erosion is the process of wind and water moving soil particles from one location and transporting and depositing them elsewhere.
