Recommended: An essay about types of soil
Select one of the following soil problems: lead, pesticides, erosion, flooding, brownfields. Find a rule/law/policy that addresses this problem. Using credible research, write a description of the soil type or specific problem, what is being done and why it makes a difference in the soil. How does the rule/law/policy protect the soil (expected and reality)? Where can this type of problem be found?
INTRODUCTION
Soil erodibility is an estimate of the ability of the soil to resist erosion based on the physical characteristics. Generally, soils with faster infiltration rates, high levels of organic matter and improved structure have a greater resistance to erosion. Sand, sandy loam, and loam textured soils tend to be less erodible to than silt, very fine sand, and clay textured soils. Sediments with high sand or silt contents and areas with steep slopes erode more easily. Similarly, this also applies to highly fractured or weathered rocks (Frankl, Deckers, Moulaert,Van Damme, Haile, Poesen, & Nyssen, 2014). Below is a law on soil erosion.
Soil Erosion and Sediment Control Act (Chapter 251, P. L. 1975). This act may be cited and referred to as the "Soil Erosion and Sediment Control Act."
LEGISLATIVE FINDINGS
The Legislature finds that sediment is a source of pollution

The largest of the primary types of soil particles is sand, which ranges between 0.05 and 2 millimeters in diameter. Silt particles are smaller than sand particles, ranging between 0.002 and 0.05 millimeters in diameter. Clay particles are the smallest of all, at less than 0.002 millimeters in diameter. Soils that are more than 50 percent sand particles are considered to be "sandy soils."Soils made up of more than 80 percent sand are simply referred to as "sand." Sandy soils tend to be easier to work than clay soils, and sandy soils are well-aerated, which helps to keep plants' roots
However, if any action is taken to defend the coastline, if you hinder in nature's course of beach erosion, there will always be after effects resulting from unnatural intrusion. This proves that any sea defence could prove a problem especially with the land owned by Nation Trust. Nevertheless if you could prove to the owners of the land to the extent of which erosion is taken place and show them how much LSD is affecting the area, action may well become a better option.
There are now many conservation programs and measures. “A lot of people in agriculture here recognize that the programs implemented as a result of the Dust Bowl are having a really important effect on holding the soil in place,” ("When the Dust Settled") People in agriculture have listened to programs implemented since the Dust Bowl. They have changed
In the United Kingdom, the Department of the Environment, Food and Rural Affairs (DEFRA) is responsible for the protection of the coastline from flooding and erosion. Responsibility for the coastline is divided between various authorities in accordance with legislation. Coastal Protection authorities such as Dover District Council are empowered under the Coast Protection Act 1949 to carry out works in their area to protect the coast from erosion. The construction and maintenance of works to resist coastal flooding is carried out by the Environment Agency in accordance with the Water Resources Act 1991. Strategic planning A key component in managing the coast has been the development [IMAGE]Of Shoreline Management Plans (SMP) which set out a strategy for coastal management of a section of the coastline.
Mississippi has a variety of different soils .The three general soils are 1) the river flood plain, known as the Delta, 2) a loess region, or bands of soils formed in windblown material that adjoins the Delta, and 3) Coastal Plain. The Mississippi Delta is better for growing row crop, while the loess and Coastal Plain region are better for animal production and forestry. The loess and Coastal Plain regions are divided based on similar soils, geology, climate, water resources, and land use called Major Land Resource Areas. The Mississippi Delta’s soil comes from sediments left by flooding various rivers in the region, rather than being a typical Delta formed by the mouth of a river. In the Delta most of the land is farmed, with three-fourths of the cropland to the north. Controlling surface water and drainage are major soil management issues. In the Delta soils are naturally diverse because of their alluvial origin. Particle sizes within the sediment decrease as distance from the originating stream increase. Another factor in Delta soil formation us surface water movement over time, because soils that formed under standing water have different properties than soils formed under moving water. Soils with large amounts of clay particles have unique features. When the soil is dry, small round aggregates form at the surface that look like shotgun buckshot, which is where the popular name for Delta clay soils “buckshot” came from. Soils with large clay content have very slow water filtration rates; this has led to significant aquaculture and rice production in the region. When floodwaters receded in the Delta, strong winds blew some of the dry sediment left by flooded river to the adjacent uplands to form the loess areas. Because of eas...
Erosion is when the elements such as wind, water, and ice remove pieces of land. (“What is Coastal Erosion?”) Coastal Erosion takes place when destructive waves wear parts of the coast away. Four ways in which this takes place are corrasion/abrasion, hydraulic action, attrition, and corrosion/solution. (“Internet Geography”) Corrasion/abrasion is when materials are hurled at the base of cliffs through waves. Hydraulic action is when waves hit the base of a cliff and air is compacted, when the wave leaves air is rushed out and often this causes the material to break. Attrition is when the waves cause rocks and pebbles to smash into each other and eventually break into pieces. Finally, Corrosion/solution is when certain types of cliff erode from the result of acids in the sea. (“Internet Geography”) Coastal Erosion is the natural process of taking land away permanently from one place to put it somewhere else. (“What is Coastal Erosion?”) Eroding coastlines are an abundant and important topic because it can change people’s surroundings in a negative way. I would like to address the questions surrounding Coastal Erosion.
Desert pavements are common landforms in arid regions. They consist of flat or sloping surfaces where stones are closely packed angular or rounded, and generally exhibit low relief (Mabbutt, 1977). Pavements tend to form on both alluvial fan toposequences and on weathering volcanic flow fields in arid regions. Soils are often found under desert pavements and they play an important role in the evolution of pavements (McFadden et. al., 1987). In the past there have been several theories as to the formation pavements and soil development beneath them. Deflation, or the erosion of finer grained particles from a surface, stone concentration by wash erosion and upward displacement of stone due to shrink and swell clay characteristics were at one time believed to be the main factors in the formation of desert pavements (Mabbutt, 1977). However, more recent research has shown that desert pavements are born and maintained at the surface, and that the soil below them is mainly eolian in origin. Slow accretion of eolian dust below the pavement is a process that eventually develops cumulate horizons. Eolian dust in environments where pavements often develop is rich in carbonate salts and clays due to the fact it often originates from nearby playa lake evaporate basins (McFadden et. al., 1987). Soils that form below the pavements over time develop calcic horizons and clay rich structure due to the influx of these eolian fines through the pavement surface. In turn the development of mature or plugged calcic horizons effects the form of the pavement surface because it alters the water drainage infiltration rate and causes pavements to decline.

As a result of the beach popularity, the landscape at Kirra has been damaged primarily due to the increasing pollution and the higher demand placed upon the beach to increase development. 2.2 Impacts of Natural Features and Processes 2.2.1 Beach Erosion Erosion is the process of wearing away the surface of the Earth. It is commonly a result of impact from wind, water and human activity. Erosion can often be categorized into a range of processes, including hydraulic pressure, abrasion, attribution and corrosion. (See Appendix A).
At Goshen College, a small liberal arts college, Land Management is one of the courses required for Environmental Studies majors. The main book required for this class is Holistic Management by Allan Savory. Savory is a well-known ecologist and author. His books cover his theories on how to take care of land. His work is so well recognized that he is known as the founder of holistic management principles. The teacher of this Land Management, Bill Minter, draws most of his lectures from the information in this book. One might make the assumption that the information in a book approved for a class such as this would not contain controversial material. Both the teacher and the students in the class assumed just this, the material within the book had subsequent evidence to back up the theories. However, this is not the case. Allen Savory’s holistic management ideas on grazing and resting the land do not work in the basic ways that he claims they do. In fact, research has been done that disputes his theories. Therefore, it has been given a great deal of criticism by other scientist.

Contaminated land is characteristically remediated to address environmental risks, risks to users of the sites, as well as financial and legal liabilities. In addition, with more and more pressure being put on our countryside for the development of new industries, business and also housing, there is an increasing tendency to build on existing sites to preserve Greenfield sites for future generations. Some of these existing sites may contaminate. The government has set targets for housing that 60% of all new housing should be built on existing "Brownfield" sites to preserve our countryside.
Saline soil is also vulnerable to erosion due to the death of vegetation that held the soil together. Soil that is eroded can ‘pollute’ water too.
Agriculture also leads to soil erosion, both through rainfall and wind. This soil can damage the aquatic ecosystems it ends up in, an...
