Soil erosion: An agricultural production challenge Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide.he impact of soil erosion on water quality becomes significant, particularly as soil surface runoff. Sediment production and soil erosion are closely related. Therefore, the most effective way to minimize sediment production is the stabilization of the sediment source by controlling erosion.

Debating How Much Weed Killer Is Safe in Your Water Glass “Atrazine is obviously very controversial and in widespread use, and it’s one of a number of substances that we’ll be taking a hard look at,” said Stephen A. Owens, who was recently confirmed as the E.P.A.’s assistant administrator for prevention, pesticides and toxic substances.

Herbicide Atrazine is thus said to have carryover, a generally undesirable property for herbicides. Glyphosate (Roundup) was introduced in 1974 for nonselective weed control. Following the development of glyphosate-resistant crop plants, it is now used very extensively for selective weed control in growing crops.

Discuss factors that contribute to soil erosion and discuss ways that soil erosion control can be integrated into forage product In general, the key to minimizing soil erosion is to avoid leaving the soil surface devoid of vegetation. The time that the soil is typically bare, and thus most susceptible to erosion, is after plowing to prepare a seedbed.

What is Soil Erosion? Causes of Soil Erosion. As mentioned, the predominant causes of soil erosion are either related to naturally-occurring events or influenced by the presence of human activity. Some of the principal causes of soil erosion include: Rain and rainwater runoff: In a particular heavy rain, soil erosion is common. First of all, the water starts to break down the soil, dispersing the materials it is made of.

Atrazine Atrazine herbicide is used in crops such as corn and sugarcane. It provides good weed control for crops because it is a selective herbicide, meaning the crop plants can metabolize the chemical, but the weeds are killed. It also has lawn care uses, like for golf courses and residential lawns as a weed killer.

Erosion Impacts of Soil Erosion- Exercise (pdf) Impacts of erosion on soil quality: Organic matter is a small fraction (2% to 4%) of soil mainly present on the soil surface. Organic matter contributes to productivity through its effect on the physical, chemical, and biological properties of the soil. Erosion gradually depletes organic matter and decreases soil productivity.

- The United States Department of Agriculture (USDA) has estimated soil erosion and has addressed erosion issues since the 1930’s. This paper discusses the impact of soil erosion and presents USDA data on soil erosion on cropland in the United States from 1982 to 2003.ata from the 2003 Annual NRI, the most up-to-date NRI information available, indicate that average soil erosion rates on all cropland and CRP land have decreased more than 38 percent since 1982. In 2003, the soil erosion rate was estimated at 4.5 tons per acre per year, compared to 7.3 tons per acre per year in 1982.

- The most acidifyingforms of agricultural production are operationssuch as lucerne hay cutting. For instance theremoval of one tonne of lucerne hay requires 70 kgof lime to neutralise the resulting acidity. Leaching of nitrogen.Leaching of nitrogen inthe nitrate form is a very important factor in soilacidity.

Erosion If the rate of erosion is higher than the rate of soil formation the soils are being destroyed by erosion. Where soil is not destroyed by erosion, erosion can in some cases prevent the formation of soil features that form slowly. Inceptisols are common soils that form in areas of fast erosion. While erosion of soils is a natural process, human activities have increased by 10-40 times the rate at which erosion is occurring globally. Excessive (or accelerated) erosion causes both on-site and off-site problems. On-site impacts include decreases in agricultural productivity and (on natural landscapes) ecological collapse, both because of loss of the nutrient-rich upper soil layers. In some cases, the eventual end result is desertification.

Soil Quality The most effective way to prevent erosion is to protect soil from rain and wind by covering it with plants and/or decaying organic matter. While industrial farms lose tons of soil because of intensive tillage (plowing), sustainable farmers have successfully reduced erosion by adopting conservation tillage techniques.

Silencing the Scientist: Tyrone Hayes on Being Targeted by Herbicide Firm Syngenta Tyrone Hayes was first hired in 1997 by a company that later became agribusiness giant Syngenta. They asked him to study their product, atrazine, a pesticide that is applied to more than half the corn crops in the United States and widely used on golf courses and Christmas tree farms.

Soil conservation From Wikipedia, the free encyclopedia. Soil conservation is the prevention of soil from erosion or reduced fertility caused by overuse, acidification, salinization or other chemical soil contamination. slash-and-burn and other unsustainable methods of subsistence farming are practiced in some lesser developed areas. A sequel to the deforestation is typically large scale erosion, loss of soil nutrients and sometimes total desertification.

- Contour Plowing & Terraces The Soil Erosion Service was one of the federal programs started in the 1930s to save the land that had been destroyed by years of wind erosion, over plowing, and over grazing. The commission taught farmers how to use terracing and contour plowing techniques to preserve the soil.

Preventing Soil Erosion on Slopes Step 4- Use Ground Cover. One of the easiest ways to limit erosion and stabilize the soil on the slope is by planting vegetation on the slope. Almost anything will help. You can plant trees, shrubs, grass and ground cover plants.The roots of the plants help to hold the soil in place, so that when it does rain, not as much is washed down the slope.Step 5- Use a Synthetic Ground Cover Fabric.oil erosion on a slope or a hill is a natural phenomenon caused by the pressure of water draining down the slope, and pushing against the soil. Trying to stop it may seem like trying to hold back the sea, but it actually can be done effectively.

- Erosion is the break down of soil particles contained in soil and dirt. Erosion occurs just as fast as it takes the soil to form so erosion consequences can be devastating if it is not controlled. Matting and blankets are the most common forms of erosion controlling methods. Researchers are always coming up with new erosion control products to help prevent and protect soil types but they are yet to know just exactly what else causes erosion.

How Rates of Erosion Are Increased by Human Activities Erosion is a natural process where wind and water transport soil and sand, slowly redefining the landscape over hundreds or thousands of years. However, some human activities can increase natural erosion rates by 10 to 15 times, leading to massive changes in an ecosystem over a relatively short period. Monitoring these changes is important, because if left unchecked, they can lead to significant environmental damage and even affect our food supply.

Soil Erosion is any process that transports soil from one place to another. At naturally occurring rates, land typically loses about 1 inch (2.5 centimeters) of topsoil in 100 to 250 years. A tolerable rate of soil erosion is considered to be 48 to 80 pounds of soil per acre (55 to 91 kilograms per hectare) each year.

SOIL EROSION - Conservation Farming Techniques SOIL EROSION - Conservation Farming Techniques. Soil erosion is defined as the wearing away of the top soil. Top soil is the top layer of soil and is the most fertile as it contains the most organic nutrient rich materials. Soil erosion can be caused by water, wind and farming practices. Accelerated soil erosion occurs when the activities of human beings disturb the natural environment, creating soil conditions which speed up soil erosion by water and wind. Some 80% of soil microbes live in the top 5cm of soil.

Soil Quality In fact, soil removed by erosion contains about 3 times more nutrients and 1.5 to 5 times more organic matter than the soil that remains behind. The National Sustainable Agriculture Information Service notes that erosion is the single greatest threat to soil productivity.
