The loss of trees, which anchor the soil in with the roots, causes widespread erosion throughout the tropics. Because of drastic climate change and extreme water fall, the soil gets washed away from the area and clogs the fresh water, going into lakes and oceans. Crop areas close by that depend on the soil and fresh rainfall get covered in this muddy water and have loose soil everywhere. Since farmers need fresh, clean soil, they have to spend money to import fresh fertilizer from other countries. Because of excessive rainfall from the loss of trees, there is flooding everywhere as well.
Soil erosion may not seem like that bad of a thing, but in reality, it is. Soil erosion can cause many problems one of them being excess soil. The widespread occurrence of water erosion combined with the severity of the impact on farmlands and urban areas have now become an urgent matter for loss of fertile farming soil. The rate and magnitude of soil erosion by water is controlled by the following factors of rainfall and runoff, soil erodibility, slope and land mass, and cropping and vegetation.
Rainfall and runoff means the more intense the rainstorm is, with less trees able to hold back the water flow, the chance of erosion is greater. The effect of raindrops from higher up will be impacting on the dirt and breaking it up causing erosion. Soil movement by rainfall (raindrop splash) is usually greatest and most noticeable during short-duration, high-intensity thunderstorms. Although the erosion caused by long-lasting and less-intense storms is not usually as spectacular or noticeable as that produced during thunderstorms, the amount of soil loss can be significant, especially when compounded over time. Surface water run off really happens when there is excess water on an area that runs off into a bigger body of water carrying things like soil. When you don't have compacted soil, air pockets in the soil will freeze and cause more runoff, carrying more dirt. Runoff from farmland is greatest during spring when the soil is typically flooded and carrying more natural soil with it.
Soil erodibility is the measure of how well specific soils do well against normal soil erosion cases like heavy rainfall. Texture of the soil is what really helps us stay compact but other factors contribute to certain types of soil. Normally erosion with higher parts of organic matter and other materials help the different soils survive with the loss of trees. Farming plows and other tools that break up dirt may help them, but it normally causes the soil to break and dry out normally blowing away or back into rainfall. Our loss of tree canopy covers the soil that should stay within a specific environment tend to move and disrupt the new area, including messing up and exposing roots. When “sealing” happens the dirt is less likely to go into run off, but it damages dampness of the soil. Many exposed subsurface soils on eroded sites tend to be more erodible than the original soils were because of their poorer structure and lower organic matter. The lower nutrient levels often associated with subsoils contribute to lower crop yields and generally poorer crop cover, which in turn provides less crop protection for the soil.
The potential for soil erosion increases if we have less trees and plant life to blanket it. Reducing erosion means that more plants are least likely to get their roots exposed and pulled out. Leaves and tree cover reduce the impact on soil. Partially covered areas allow excess water to get through, possibly not down to the roots and going into runoff streams killing plant life and excess non-fresh water. Weather also affects this, like winter and with the leaves gone there is nothing to cover it from snowfall and melting in the spring. Crops that provide a full protective cover for a major portion of the year can reduce erosion much more than can crops that leave the soil exposed for a longer period of time. To reduce most erosion in non covered tree or bush areas, farmers for example can use natural water flow systems instead of plowing and breaking up the compacted dirt decrease run off.
