What agricultural practices controls soil erosion


  1. No-Till Farming. No-Till Farming is an agricultural practice that does exactly as the name implies: it eliminates tilling from the farm.
  2. Covering Bare Soils. Barren and exposed soils are the most susceptible to soil erosion. …
  3. Managing Your Slopes. If your farm has steep topography then soil erosion is a major risk. …
  4. Agrochemicals Contribute To Soil Erosion. While sometimes it seems like the only option, the use of agrochemicals like fertilizers and pesticides can actually greatly contribute to soil erosion.

Crop rotations using high residue crops (corn, hay, and small grain) produce large amounts of residue that help control erosion. No till planting reduces erosion by keeping more resi- due on the soil and less soil disturbance.


How can soil erosion be controlled?

Improving the soil infiltration rate, resulting in less surface runoff, can lead to reduction of soil erosion. Agronomic, cultural, or structural practices are available for controlling soil erosion.

How can farmers reduce the threat of erosion in undulating landscapes?

Learn about management practices such as no-till, reduced tillage, cover crops, and contour farming to reduce the threats of erosion. No-till drilling wheat into soybean stubble allows maintenance of residue cover and no soil movement for excellent erosion control in undulating landscapes. Photo: Sjoerd Duiker.

What are the Agronomical measures to control erosion?

The agronomical measures are referred by the practices of growing vegetations on mild sloppy lands to cover them, and to control the erosion from there. The lying vegetation on the soil surface dissipates the erosive power of erosion agents, either they are water or wind.

How can we prevent gully erosion in agricultural fields?

The most common conservation practice to address ephemeral gully erosion in fields is a grassed waterway to stabilize the area of concentrated flow. Other practices include methods to shorten the slope such as strip cropping, terraces, or diversions. Further, contour planting and contour buffer strips are ways to improve infiltration in-field.


How can agriculture prevent soil erosion?

You can reduce soil erosion by:Maintaining a healthy, perennial plant cover.Mulching.Planting a cover crop – such as winter rye in vegetable gardens. … Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.More items…

Which practice helps reduce soil erosion?

Contour farming and terracing: The practice of tilling sloped land along lines of consistent elevation in order to conserve rainwater and to reduce soil losses from surface erosion.

A healthy soil

The soil has many functions, usually referred to as ecosystem services. Food and water filtration are 2 examples of such services.

Accelerators of soil erosion

There are many arguments in favor of sustainable agriculture. One of the most important is that it conserves the soil. Excessive soil erosion is one of the world’s most significant ecological problems.


Water and wind are the most important agencies of soil erosion. Tillage decomposes the topsoil, giving water and wind all the space they need. They both remove the fertile topsoil.


Slash and burn is a century-old practice, turning forests into farming land. The land left behind is prey to water and wind. This process is accelerated because the surrounding, and now cut away forests, retained water and kept the fertile topsoil in place.


Sustainable agricultural practices are the most effective methods to prevent soil erosion and restore eroded soils. Of course, forestation is also an important way to prevent soil erosion and restore affected soils.

Sustainable agricultural practices

Forests and shelterbelts also create microclimates for crops. In permaculture, this is one of the most significant conditions. Other sustainable agricultural practices which are favorable to healthy topsoil are mixed-cropping and crop rotation.

What are two farming practices that can reduce erosion?

Contour farming and reducing tillage are two practices that can help reduce erosion.

What farming practices cause soil erosion?

Tillage, Soil Compaction and Erosion Mechanical tillage and the use of heavy farm equipment can cause both soil compaction and soil erosion if soils are not managed effectively.

What are two farming practices that can reduce erosion caused by water?

Reduce Tillage. Reducing tillage allows crops to remain in the soil rather than being plowed at the end of a season.

What are the 4 types of soil erosion?

1) Sheet erosion by water; 2) Wind erosion; 3) Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides; 4 ) Gully erosion – when water runoff removes soil along drainage lines.

What is the largest cause of soil erosion?

Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.

What are 5 ways to prevent erosion?

Plant Grass and Shrubs. Grass and shrubs are very effective at stopping soil erosion.

What are the five ways of controlling erosion?

Planting Vegetation. This method involves planting crops with deep roots that can hold the soil in place.

What is soil conservation?

Soil conservation is a land preservation technique, in which deterioration of soil and its losses are conserved by using within its capability and applying conservation measures for protection as well as improvement.

How does vegetation help a land?

The vegetation helps in reducing the overland flow/surface runoff and soil erosion both .

What is wind strip cropping?

The wind-strip cropping is a well-known agronomical practice, used for controlling the soil erosion in wind erosion susceptible areas. The role of agronomical measures for soil & water conservation has immense importance, perhaps much more than the others.

What are agronomical measures?

The agronomical measures are referred by the practices of growing vegetations on mild sloppy lands to cover them, and to control the erosion from there. The lying vegetation on the soil surface dissipates the erosive power of erosion agents, either they are water or wind.

How does mulching affect soil?

2. The mulch tillage increases the infiltration capacity of the soil by maintaining the upper soil surface, more permeable. 3. The obstacles caused by leaves, stems and roots over the field, reduce the velocity of surface flow; and thus controlling the sheet erosion.

What is the first line of defence in agronomical measures?

The use of agronomical measures is entirely dependent on the soil types, land slope and rainfall characteristics. In soil and water conservation programmes, the agronomical practices are counted as first line of defence, the second is mechanical or engineering measures which are employed to check the soil erosion, immediately.

What is a bund in engineering?

It is an engineering soil conservation measure, used for retaining the water, creating obstruction, and thus controlling the soil erosion/soil loss . Bunds are the embankment like structure, constructed across the land slope. When they are constructed on the contour of the area, are called contour bund; and when grade is provided to them, then they are known as graded bund.

What are some ways to reduce soil erosion?

Barren and exposed soils are the most susceptible to soil erosion. Keeping your soils covered with organic mulches or vegetation is one of the best ways to reduce soil erosion. Aside from reducing soil erosion, using mulch or cover crops provides other benefits to your soils.

How can we reduce erosion?

By slowing, sinking, and spreading water you greatly reduce erosion and retain more water in your landscape. This can involve the building of swales, terraces, or earthen mounds that alter the movement of water. Areas with excessive rain will have to design their earthworks differently than those in arid climates.

How does soil erosion occur?

Soil erosion occurs when soil is mobilized and transported away from a region, usually by the force of wind or water. It often occurs on bare soils that have been disturbed by poor agricultural practices, overgrazing, or forestry.

How much of the world’s topsoils are lost due to soil erosion?

According to the World Wildlife Fund website on Soil Erosion and Degradation, humans have been responsible for the loss 50% of all topsoils!

Why is soil important to the world?

Unfortunately, soil erosion around the world is leading to mass degradation of soils leaving farmers …

What are the effects of modern agriculture on soil?

Many modern agricultural practices cause accelerated rates of soil erosion and end up costing farmers the health of their soil. If you’re a farmer this means the more you’ll have to spend on soil amendments and pesticides, many of which will cause further soil deterioration.

What happens to the top of the soil?

Soil Erosion Destroys Your Top Soil. The first couple inches of your soil is the most important and biologically active part of your soil. If free from erosion, organic matter and soil nutrients accumulate here to form the fertile dark soils.

How does soil erosion affect agriculture?

Soil erosion can negatively impact agriculture by reducing crop yields and quality. In an era where the population continues to grow rapidly, the agricultural sector is being put under increasing pressure to respond and produce enough food for our growing society.

What is the process of soil erosion?

Soil erosion refers to the process whereby the top layer of soil is removed. While it is a natural process, caused by the weather, it is also caused by human activity, and it can cause harm to agricultural processes when it occurs rapidly and excessively. One of the leading causes of soil erosion is deforestation.

Why is it important to protect the land that food is grown on?

This highlights the vital need to protect the land that food is grown on to prevent a food crisis. With the soil being eroded at rates between 10 to 40 times faster than the rates at which it is being renewed, it is essential to address the causes of soil erosion to limit the detrimental effects to agriculture.

How much of the world’s agricultural land is affected by erosion?

It is estimated that as much as 80% of the world ’ s agricultural land is suffering from what is considered moderate or severe levels of erosion. Also, almost all human food source comes from the land, with an estimated 99.7% of food calories coming from this source and just 0.3% coming from aquatic ecosystems.

Can grazing animals cause soil erosion?

Agricultural processes themselves can also cause soil erosion. Grazing animals can induce this effect by eating the plants covering the topsoil, exposing it to the elements, and churning up the ground pacing back and forth over its surface.

How does erosion affect agriculture?

Erosion from wind and water annually robs our nation’s farms of billions of tons of soil. In fact, US farms are currently losing twice as much topsoil to erosion per year as the Great Plains lost in a typical year at the height of the 1930s Dust Bowl, one of the most devastating agricultural and social disasters in our history.

How to keep soil in place for farmers?

And there are several specific strategies farmers can use to do this: Plant cover crops. By keeping roots in the ground year-round, cover crops help keep soil in place and maximize its water-holding ability, making it more resistant to floods and droughts.

What were the effects of the Great Depression on the Great Plains?

During the early decades of the 20th century, farmers dramatically expanded unsustainable grazing and farming throughout the Great Plains. In particular, farmers encouraged by rising wheat prices in the 1910s and 1920s plowed up millions of acres of deep-rooted native grasses and adopted farming methods that made the soil a sitting duck for erosion. Later, when the Great Depression struck and wheat prices fell, desperate farmers plowed even more grassland.

Why is soil important for cover crops?

Healthy soil resists erosion well, especially if it is protected by plants above ground and roots below-ground year-round (which is one of the reasons why cover crops are so important).

What is the Agriculture Resilience Act?

It’s in everybody’s interest to support US farmers in rebuilding soil health and preventing erosion through policies, such as the Agriculture Resilience Act of 2020, that can ensure a transition that benefits all. Photo credits: Tillage and erosion in a plant field by USDA NRCS South Dakota. Healthy soil cross section by USDA NRCS.

What was the federal government doing to help the Plains?

Among many measures taken in response to this ecological disaster, the federal government took steps to improve soil conservation and fight erosion, including the establishment of the Soil Conservation Service, which still exists today as …

What happened to the grassland in the 1930s?

Then, starting in 1930, a sustained period of severe drought began, putting bare, degraded soil at the mercy of the region’s high winds. The resulting dust storms brought widespread devastation, bankrupting farms …
