Extracted soil samples indicate simultaneous reduction of rainfall and occasional erosion. Both soil and sediment features show establishment of marked
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
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.
Soil is the word that literally holds this world together. Without the necessity of soil, we probably wouldn’t even be where we are today. It is the main support system for our earth because it holds the roots to the ground, keeping our ground in tact. When we can’t control what happens in nature, like the Dust Bowl, we may be hit with unexpected dangers, but when it comes to things we can control we need to act right away. In the 1930’s, with little to no rainfall, weak soil and no advanced technology the people in the great plains were headed for a major catastrophe. They had no control over the way their land was moving, so it just kept going and eventually ended up to be known around the world as the Dust Bowl. If they would have had the
Compacted soil can result in soil that is unable to create a run-off surface. If this happens, the water will be unable to seep into the soil and irrigate the crop. Tractors passing over soil can cause this compaction to occur, which is why tilling is a more effective way to stir up the soil. And as a bonus, tilling can help get rid of weeds, so it is a win win.
Introduction With soil being washed away nearly 10 – 40 times faster than it is being replenished1, every single idea to avert this this crisis needs to be considered. No till farming, a method by which farmers implement a way of growing crops with minimal disturbance to the soil and the soil’s abiotic and biotic components, is a very important idea that is being employed worldwide with notable results. With food prices rising and people turning to their own backyards to grow food, the potential advantages of small scale no till can play a major role in the health and regeneration of our
Erosion has the ability to ruin large buildings or simply be an inconvenience to someone. Erosion happens gradually and it happens by wind or water breaking pieces of an object. Humans are said to have made the process faster. We are tearing trees and dirt and replace

Soil is the most important element for agricultural ecosystems. Healthy soil comes with beneficial microbes and insects. Unfortunately, these are often killed off by the abuse of pesticides. Healthy soil can produce strong crops that are less vulnerable to pests. Damaged soils often need strong fertilizers application to produce a high amount of crops. Soil quality can be amplified in many ways, including leaving crop remainders in the field after harvest and adding composted plant material (Union of Concerned Scientists) Compared to industrial agriculture, companies continue to damage and consume natural soil. While intensive plowing and monocrop (does not rotate) agriculture systems have caused nutrient exhaustion and soil erosion. Excessive application of fertilizers and pesticides has contaminated soils and polluted waterways (Grace Communications Foundations)
Introduction: Erosion is destruction on the rangeland from wind, water, cattle, and other natural agents. The process where the Earth gets worn down and removes material from the top of the soil. Erosion has been dated back to Plato and Aristotle (Montgomery et al 2007). There are many types of erosion, water erosion, sheet erosion, gravitational erosion, and wind erosion (Zonghu et al 1991). Water erosion is mainly in fields, where rilling would take place (Evan and Morgan 1974). Water erosion usually happens due to the lack of cover on the rangelands, and heavy rainfall will destroy plants, and even move the soil. Wind erosion is the most common type of erosion. One of the greatest problems in the United State is the wind shifting the soil surface (Pierson et al 1961). Livestock such as cattle (Bos taurus) also pose a threat to the landscape. Hart (1949) did a study on dairy farms, and found excessive gully erosion. Land with erosion losses the ability to hold water for the soil (Gifford and Whitehead 1982; Boardman and Mortlock 1993) while also losing key nutrients such as

The soil quality is important for the soil to perform these functions. Land and soil quality is important to agriculture, but so is plant and the animal systems. The can be defined as ecosystems, and agriculture is an agroecosystem. The ecosystem links between the function of soil, water, and air. Changing concepts have been made from management of a single-resource, single species approach to making it a multiple management approach that would involve the structure, composition, and function of the entire ecosystems. Soil quality can be defined as the capacity of soil that is to function with ecosystem boundaries to sustain biological productivity that will maintain environmental quality, and promote plant and animal health (CEQ, 1993).
One method of conserving soil is terracing.Terracingcreatesdifferentlevelareasona hillside. Steps would then be created because each level would be higher. This decreases erosion because because soil barriers are created by the terraces. Another method is crop rotation. This method is when you rotate crops over time when you are farming. Crop rotation prevents soil depletion, maintains the fertility of the soil, and minimizes erosion from water by reducing overland
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
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,
