Question

How do plants prevent erosion?

Answer 1

Soil erosion is the upper layer of soil being displaced; it is a form of soil depletion. The complex operation of erosive agents, that is, water, ice (glaciers), snow, air (wind), trees, animals and humans, triggers this natural phenomenon.

Complete answer:
For the following purposes, plants have protective protection on the field to discourage soil erosion:
1. Plants slow down water as it passes through the surface, causing more of the rain to sink into the ground.
2. The roots of plants secure the soil in place to avoid it from being blown or flushed away.
3. Tree cover tends to decrease the effect of drops of rain.
4. Grassy cover contributes to reducing pollution.
5. Roots bring the fragments of soil together in place.
All this serves to prevent surface depletion and also improves the amount of regeneration of groundwater.

Intensive irrigation, forestry, highways, anthropogenic climate change and urban sprawl are among the most significant human actions in terms of their impact on erosion stimulation.[4] However, certain mitigation and remediation practices will mitigate or restrict vulnerable erosion In an undisturbed forest, a layer of leaf litter and humus cover the mineral soil. Over the soil, these two layers form a protective mat which absorbs the effect of rain drops. Urbanization has a direct influence on erosion processes, first by denuding the vegetative cover property, changing drainage patterns, and compacting the soil during construction; and next by coating the land with an impermeable asphalt or concrete sheet that increases the volume of surface runoff and increases the velocity of surface wind. It is expected that the warmer air conditions experienced over the past decades will contribute to a more intense hydrological cycle, with more severe rainfall events. The rise in sea levels due to climate change has already raised coastal erosion rates dramatically.

Note: The cover crops are excellent plants for erosion control, such as vetch, rye and clover. Such hardy, easy-to-grow plants send out root nets that help keep topsoil in place while reducing competitive weeds as well. They increase the nutrient density when they compost when tilted back into the soil.
