The Cause And Effects Of Soil Erosion?

Morialta Conservation Park is a protected area located in South Australia, Australia. The park covers an area of 533 hectares. It is set in a bush environment with several hikes to walk. It has a narrow gorge, consisting of three waterfalls.

One theory in Jared Diamond s Collapse is that soil degradation and erosion leads to insufficient agriculture and a society s demise. In Timothy Egan s The Worst Hard Time, he sets forth in specific and excruciating detail exactly what Diamond outlines in Collapse. Only Egan s book isn t theoretical. It isn t a survey of what s happened in other countries. It s about the Dust Bowl in the 1930s. It s about what happens, right here in the heart of America, when the land is misused, mistreated, and turns on those who depend on it.

The excess use of fertilizers can result in soil erosion and can lead to land pollution.

7 The concept of the soil conservation way to limit the plowing, and to stop the tractors to pick up and release dust into the sky If the act was not put into place the land would continue to get worse, but only until the sky came.

Soil organisms provide ecosystem services such as maintaining soil fertility and preventing soil erosion. Water, wind, ice, and other agents cause soil erosion, the wearing away or removal of soil from the land. Soil erosion reduces fertility because essential minerals and organic matter are removed. Erosion causes sediments and pesticide and fertilizer residues to pollute nearby waterways ( Wiley, 2009).

Soil turnover - as soil is moved around by digging animals, organic matter is mixed through which distributes nutrients throughout the soil

I watched a Ted Talk on YouTube called Ted x Huntsville, it was presented by Karen Wynne and was published October 1st, 2014. The topic that Wynne talked about was the concept of stopping treating soil like dirt. She started by stating a quote by Leonardo Da Vinci that said: “We know more about the celestial bodies than the soil under our feet”. This was an interesting way of introducing her talk since after saying we near nothing about earth she begun to tell us the difference between soil and dirt introducing the topic at hand. For soil she gave the basic definition that it was a mixture of sand, silt, and clay plus air holes, water, and organic matter and as for dirt she just simply washed her hands on her shirt as if it was nothing after playing with the soil. So, already she was hands on and showed that we humans don’t really care about our soil.

I found out a couple things about coastal erosion. One is that it affects everyone who lives on a coast directly

There are many ways to conserve soil. Windbreaks, cover crops and crop rotation are some methods to conserve soil. Windbreaks are tree lines that are planted around crop fields to provide shelter from the wind which in turn protects the topsoil from erosion. Cover crop is a crop that is planted just to occupy the land but they are not always harvested because the land is occupied by crop year round this reduces soil erosion. Crop rotation is a set of crops planted in order and repeated yearly. Examples of crop rotation are corn could be planted one year, wheat the following year and hay the third year. Crop rotation has various benefits such as the soil health is increased, the water absorption into the soil is increased and most importantly soil erosion is

Deforestation’s accompaniment is erosion. Since much of strip mined land lacks proper restoration, weather causes further loss of soil and vital nutrients needed for native vegetation to grow. “Mountain Top Mining and Valley Fills Report” published by the EPA cites KA Harper and others educated and conducting studies in the fields of biology, environmental studies, and renewable sources. According to Harper, the change in mineral content of land affected by surface mining prohibits growth of indigenous plant life and allows foreign plant life to invade, changing the areas ecosystem (Harper).

Franklin D Roosevelt once said, “the history of every Nation is eventually written in the way in which it cares for its soil.” The United States began seeing sustainable management practices in farms, and healthier soil through this act. In 1982 through 2007, the United States soil erosion had declined by 43%” (Montanarella, 2015). Every year the United States loses about $400 billion dollars due to crop soil that is eroded. Soil is a limited resource and the largest resource for growing food, accommodating diverse ecosystems, and providing food resources. Therefore laws, acts, and provisions are necessary to protect this natural resource.

Congress declares soil erosion “a natural menace”. Under Hugh B. Bennett, the SCS will develop programs to save the topsoil and irreparable damage to the land. New farming techniques are put in place and farmers are paid to practice soil-conserving techniques as

Erosion removes the surface soils, containing most of the organic matter, plant nutrients, and fine soil particles, which help to retain water and nutrients in the root zone where they are available to plants. Thus it affects the productivity of plants. The remaining, the subsoil, tends to be less fertile, less absorbent and less able to retain pesticides, fertilizers, and other plant nutrients. There are over 17,000 soil types recognized worldwide. They vary widely in structure, erodibility, fertility, and ability to produce crops. A generalized soil profile for a humid, temperate climate is showed. When the natural vegetation is cleared for agriculture, soils become exposed to erosion and loss of soil fertility. The removal of the above-ground natural

The decline of the environment due to natural and human exertion is known as the degradation of the environment. The natural weather occurrences such as heavy rain, flooding, storms, earthquakes, volcanoes etc. are not administered under human control. These meteorological phenomenon’s wreak devastation on the environment from time to time causing the land to become unsuitable to cultivate. On this subject matter, the human population does not contain the power to stop the wrath of Mother Nature. Rather, we are forced to sit back and watch. Nevertheless, humans engage in a crucial role towards the degradation of the environment in which we live in. Unavoidably, the degradation of the environment is a rising and utmost worldwide subject. I accept that the root cause to environmental degradation is the excessive use of resources on our land utilized by the processes under capitalism. As Jensen wrote in Endgame, “The global industrial economy is the engine for massive environmental degradation and massive human and (nonhuman) impoverishment.

Significantly, desertification also cause soil erosion, which means soil surface is worn by wind and water. Desertification makes soil easy to erode by water or wind, as soil is exposed and soil structure is instable without forest. LaI R(2003) says that ““Land area globally affected by erosion is 1094 million ha (Mha) by water erosion, of which 751 Mha is severely affected, and 549 Mha by wind erosion, of which 296 Mha is severely affected.” To control soil erosion, an obvious way is virescence, enlarging forest cover, which can protect the soil far from exposing to strong wind. Also, the roots of plants under ground play a role as a framework, as they are obstructions to soil movement,
