Trees and soil erosion

Trees, soil and water. The crops that feed the cities are raised in the valleys and flat river plains, but the fate of the valleys is decided in the hills and mountains where the streams rise. Where the hillslopes and ridges in the upper reaches are covered with trees, the streams flow clearly and steadily and all is well in the valleys below. Soil erosion is the movement of soil from one place to another and may be caused by wind, water or human activities. The process can occur naturally over a long period of time, or it can occur quickly with unusual weather events or excessive vegetation removal. Erosion affects both farmers and home ... A lack of windbreaks (trees, shrubs, crop residue, etc.) allows the wind to put soil particles into motion for greater distances, thus increasing abrasion and soil erosion. Knolls and hilltops are usually exposed and suffer the most. It involves planting crops in strips or alleys between rows of trees of shrubs that can provide fruits and fuel wood. Even when the crop is harvested, the soil will not be eroded because trees and shrubs still remain on the soil and hold the soil particles. Automotive exhaust partsAs a result, the lack of land cover causes increased rates of soil erosion. Trees and vegetation cover help to hold the soil particles together thereby reduces the erosive effects of erosion caused by rainfall and flooding. Deforestation and urbanization are some of the human actions that have continued the cycle of soil loss. While erosion is a natural process but human activities are speeding up the process by 10-40 percent globally. Deforestation, intensive agricultural practices, urban sprawl and climate change are among the common factors that are accelerating soil erosion. The soil is considered a non-renewable resource, while technically it is a renewable ... Plant roots bind the soil particles together and prevent erosin. Erosion is loss of top soil along with nutrients which takes place specially during rains. Tree cover helps in reducing the impact of rain drops. Grassy cover helps in reducing runoff. Roots hold the soil particles together in place. All this helps in preventing soil erosion, and also increases amount of groundwater recharge. ()

How do bounty hunters make moneySoil compaction can influence plant height by preventing normal root development. This is most detrimental if it’s shallow compaction (6 to 8 inches). If timely rains don’t soften the compacted layers so roots can penetrate the soil, plants will be stunted, and have fewer fine roots and less overall root mass.

Trees help prevent water pollution. Trees reduce runoff by breaking rainfall thus allowing the water to flow down the trunk and into the earth below the tree. This prevents stormwater from carrying pollutants to the ocean. When mulched, trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies. Trees minimize soil erosion from surface water runoff and flooding. This helps maintain soil health and prevents silt deposition in water bodies.
