The National Resource Conservation Service (NRCS) was established in 1933 in response to a catastrophic event in the Southern Great Plains region know as the “Dust Bowl” or “Dirty Thirties”. In 1869, the railroad made its way to the Great Plains and became home to the many early settlers who took advantage of the “free soil” or land tracts offered by the government via the Homestead Act; a bill enacted in hopes to curb slave labor and increase the number of individual farmers who owned and operated their own farms.…
Over cultivation is the practice of repeatedly cultivating and growing crops more rapidly than the soil can regenerate, leading to a decline in soil quality and productivity. Preparation in growing crop and after the harvest of crop, the soil is left exposed to erosion. Water and wind cause this erosion to take place. Plowing is frequently considered necessary to loosen the soil to improve aeration and infiltration through it, yet all too often the effect is just the reverse. The weight of the tractors cause the soil to become impacted which makes the soil more susceptible to erosion.…
The "Dust Bowl" phenomenon occurred throughout western Oklahoma and Kansas and in the Texas panhandle. Severe drought during the 1930's had led to massive agricultural failures in the Southwest. These areas had been heavily overcultivated by the wheat farmers for the last decades and were covered with millions of acres of loose, uncovered topsoil. Without precipitation the crops withered and died. The topsoil, which did not have any anchoring roots, was picked up by the winds and carried in billowing clouds across the region. Huge dust storms blew across the area, at times blocking out the sun and even suffocating those caught unprepared.…
The Dust bowl was one of the worst droughts in history and it was so bad when you plow a field and you are going to plant the wind has put a new…
First there is Overcultivation which is the practice of repeatedly cultivating and growing crops more rapidly than the soil can regenerate , then that leads to a decline in soil quality and productivity. This is the preparation in growing crops and after the harvest of crop, the soil is left exposed to erosion. The water and wind is what causes the erosion to take place. Plowing is frequently necessary to loosen the soil to improve aeration and infiltration through it , yet all too often the effect is just the reverse. Weight of tractors causes the soil to become impacted which in effect makes the soil become impacted which makes the soil more susceptible to erosion. Overcultivation erosion can be corrected by no-till agriculture . This is a technique that permits continuous cropping , yet it minimizes soil erosion. No – till agriculture is when the field is sprayed with herbicide to kill weeds and then planting apparatus is pulled behind a tractor to accomplish several operations at once . This method prevents the soil from becoming compacted because all the harvesting steps have been minimized to just one step. Some other strategies to minimize overcultrivation are low-till farming and uses of fertilizers. These strategies have minimized the processes of soil erosion. Even though , money is lost and time is needed with the improving the methods used to correct overcultivation it is necessary and beneficial to farmers and consumers in the long run.…
The Dust Bowl began on Thursday, April 18, 1935, it was a huge, black, cloud of dirt, piled up on the western horizon. This storm was enormous and deadly. The Dust Bowl affected Oklahoma, Texas, parts of Kansas, Colorado, and New Mexico. These states were vulnerable to the dust storm due to their lack of rainfall, light soil, and high winds. As a result, soil lacked the the strong roots of grass in order to stay in place, this made it easier for high, hectic winds to get a hold of the soil. Years before the Dust Bowl, ranchers and farmers looking for new land to grow crops and maintain live stock stumble across this land. Hoping to finally settle down and start their business; however, on 1935, the very land that gave them hope, now gave them…
History records many such examples of agricultural communities flourishing and then failing, often because farming eroded the soil, exhausted the soil’s nutrients or caused a build-up of…
The Eurocentric view of desertification puts the blame on pastoral nomadism. This is an issue because the cultivation of arid and semi-arid lands in regions like the Sahelian region of Africa is helped by the fact that the soils are usually rich in nutrients since, unlike wetter areas, the limited rainfall has historically washed only a smaller proportion of nutrients from the top soil to the lower soil levels. There are also long hours of sunshine to provide the raw energy for the growth of plants. However, the rainfall is sparse, leading to inconsistent crop yields. (Granger 1990).…
An example of poor techniques was the "Dust Bowl" in the mid-western states of the U.S.A. in the 1930's. Farmers exhausted the soil by monoculture and left the soil bare after harvesting. Soil erosion is a problem of the developed world as well as the developing…
Desertification is the most serious consequence of soil degradation. Desertification is the gradual transformation of habitable land into desert. It is caused by climate change and improper use of land. The soil becomes more degraded and has less nutrients and it can’t support vegetation and therefore turns to desert. It is a problem in the Sahara Desert and Kalahari Desert. What makes soil degradation a significant threat in the Kalahari Desert is that it is nutrient deficient and subsistence farming. Political changes such as disrupted communal land ownership patterns also had an impact on desertification. Plant removal by grazing can increase wind and water erosion reducing soil nutrient and destroying the soil structure. The case study on soil degradation in Australia shows that low rainfall can also cause desertification. The Murray-Darling basin produces more than a fifth of Australia’s food and there is a critical decrease in rainfall. The land contains half the amount of carbon it did before European settlement due to low rainfall with harmful farming techniques. This leaves the soil unable to hold as much water. Desertification…
This paper will go in depth on soil erosion caused by farms. It will primarily look at how soil erosion from farms can affect the environment. The paper will then go in depth with seven supporting questions which include, what causes erosion, how erosion from runoff affects the land, how it affects watersheds, the chemicals that are caused by erosion, how it affects us locally, ways to prevent it, and ways to clean up what has already been done.…
As a natural resource, soil is of immense value to man. In the agricultural orient the distribution and density of population have conformed to the persisting patterns of soil fertility and productivity.…
There are two different schools of thought about farmers’ perception of soil erosion. One school believes that due to the insidious nature of the pervasive hazard of soil erosion, farmers misperceive either the existence or extent of erosion on their own farm (Yusuf…
When agriculture fields replace natural vegetation, topsoil is exposed and can dry out. The diversity and quantity of microorganisms that help to keep the soil fertile can decrease, and nutrients may wash out. Soil can be blown away by the winds or washed away by rains.…
