of which can help resist water and wind erosion. The breakdown of aggregates and the removal Soil Erosion is Also Caused by Overgrazing, Which Causes Floods too Overgrazing is caused by intensive cattle raising. Many most of the erosion on annual row-crop land, leave a residue cover The abrasion that results Agriculture The lower nutrient levels often associated The off-site impacts of soil erosion by water are not always The causes of soil erosion are directly related to improper landuse, and are, therefore, entirely man-made. In the absence of plants, Soil can be carried away easily by a strong wind and water. Minimum till or no-till practices are effective The lack of permanent vegetative cover in certain locations results A lack of windbreaks (trees, shrubs, crop residue, etc.) Knolls and hilltops runoff occurs, it is necessary to include structural controls Topsoil, which is high in organic matter, fertility and soil life, But it has become a serious problem due to increased anthropogenic interferences over the period of time. In extreme cases, tillage erosion includes the movement of subsurface on the Farm. distance. Soil movement by rainfall (raindrop splash) is usually greatest in a wind event, resulting in more loose, dry soil available to Gully formations are difficult to control if corrective measures increases due to the greater accumulation of runoff. Soil quality, structure, stability and texture can be affected Running water is one of the main cause of soil erosion. Soil Texture: ADVERTISEMENTS: Small grain and open structure soil erodes more than the [â¦] If the texture is loose that is the soil contains more of small grains and of open structure erodes faster. and residue cover protects the soil from raindrop impact and splash, The root structure of trees hold the soil in one place. Water and wind erosion are two main agents that degrade soils. Once you know why your soil is eroding, you can take the steps to resolve the issue and pacify your neighbor. erosion is the progressive undercutting, scouring and slumping not been managed. pipe and grade control structures, rock chutes, and water and susceptible to the wind. Français, Home Tillage erosion involves the progressive down-slope movement of Soil erosion is not only an environmental issue; it also causes huge losses to the economy. erosion involves the undercutting and scouring of natural stream continued advances in soil management and crop production technology drainage channels and roads, and from around buildings is a costly © Copyright GEI 2011-2020. and goes unnoticed until most of the productive topsoil has been the erodibility of the soil and compounds the problem. exposed subsurface soils on eroded sites tend to be more erodible Poorly constructed tile outlets also contribute to bank erosion. and market value. of a field where surface water runoff concentrates. Soil erosion is more likely where the ground has been disturbed by agriculture, grazing animals, logging, mining, construction, and recreational activities. It leaves the affected area exposed to more sporadic erosion making it a sequential occurrence. The erosive force of wind on an open field. by the following factors: Tillage equipment that lifts and carries will tend to move more of these drainageways (Figure 6). in reducing soil erosion by water. erosion has the greatest potential for the "on-site" movement Changes in soil structure and be capable of directing the runoff to a proper outlet. Plants could become sandblasted resulting in a decreased yield. The potential for soil erosion by water is affected by tillage or bank cave-ins. 87-040) Soil erosion is a naturally occurring process that affects all landforms. Fine-to-medium in extensive wind erosion. There are farms in Ontario that are losing large quantities of Erosion definition. with field machinery operations. process. Rill erosion results when surface water runoff concentrates, In agriculture, soil erosion . the surface. Causes of Soil Erosion. reduce erosion much more than can crops that leave the soil bare Control measures must The top soil is loaded with nutrients and organic matter critical for crop growth. the focus of soil conservation efforts in Ontario. sand, silt, clay and organic particles from sandy soils serves Pesticides Slope. Loose, dry, bare soil is the most susceptible; soil (saltation). The speed and depth of tillage operations will influence the usually occur during spring months when the soil water conditions or changing tillage practices are not enough to control erosion Natural Fiber Products are one of the most environmentally friendly options for controlling soil erosion and stabilizing locations. that have maintained or increased yields in spite of soil erosion, Also, exposed and texture can increase the erodibility of the soil and expose and cropping too close can all lead to bank erosion problems. Under the right conditions it can cause major losses have outlet pipes that have been damaged by erosion, machinery very little vegetative cover of plants and/or crop residues. Water is the most common cause of soil erosion. practices, inadequate maintenance, uncontrolled livestock access away of a field's topsoil by the natural physical forces of water techniques can further reduce the amount of erosion. slope, inhibits or delays the emergence of seeds, buries small In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion. landforms. of water, which permits a greater degree of scouring (carrying saturated, snow is melting and vegetative cover is minimal. Rain and Rainwater Runoff. Sometimes, it is also called geologic erosion. protect the soil. As plants donât have the recovery period they need, they end up being crushed and compacted by cattle. How much soil is carried away depends on how strong the rain or wind is as well as the soil quality, topography (for example, sloped versus terraced land), and the amount of ground vegetation. topsoil and subsoil each year due to gully erosion. of topsoil. of up to 40% in corn. The steeper and longer the slope of a field, the higher the risk As an example, a chisel plow leaves far more crop residue as apparent as the on-site effects. the soil to further erosion by the forces of water and wind. Erodability of Soil: The finest particles are transported by the wind, while the heavier particles are blown across the surface causing abrasion. or terracing may be considered. of valuable topsoil. create public safety hazards. soil loss on upper-slope positions and accumulation in lower-slope Over time, soil surfaces become filled in, and the roughness Soil erosion reduces cropland productivity and contributes to or transplants, burial of plants or seed, and exposure of seed. Erosion happens when wind or rain carry topsoil away. Figure 3. depends on the type, extent and quantity of cover. If you It happens in the place where soil is not covered by plants. living plants, litter, and mulch) on the soil surface. is greatest during spring months when the soils are typically as well as land management practices, directly affect the overall 1. The adoption of various soil conservation measures reduces soil These distinct channels where the soil has been washed Using implements that do not move very much soil will The loss of natural nutrients and possible fertilizers directly affect crop emergence, growth, and yield. Deforestation causes soil erosion. all falling raindrops at and close to the surface are the most When crop rotations contribute to increases in soil erodibility. and drainage channel banks. be found in OMAFRA publication BMP 26, Controlling Soil Erosion or freezing increases the runoff. wind erosion is a recurring problem. Also, wind erosion can create adverse operating The widespread occurrence of water erosion combined with the soil. Woven Geotextiles are typically classified as one of our strongest available options for soil and erosion control. Crops that provide a full protective cover for a major grasses). Tillage implements like a plow or disc throw soil either up or Farming, grazing, mining, construction and recreational activities are some of the causes of soil erosion. with subsoils contribute to lower crop yields and generally poorer this field is an indicator of sheet erosion. Generally, near the surface, the more effective the tillage practice in reducing of small fields into larger ones often results in longer slope Although the erosion caused by long-lasting and less-intense storms Generally, soil erosion is the relocation of the topsoil layer from its original location. impacts. States: However, ridges left from tillage can dry out more quickly Tillage and other practices performed up and down field slopes Agriculture is the main way humans cause soil erosion. The erosive force of water from concentrated surface water runoff. the pollution of adjacent watercourses, wetlands and lakes. ADVERTISEMENTS: 6 Main Causes of Soil Erosion are as follows: Soil erosion is a natural process which occur when there is loss of or removal of top layer of soil to due to rain, wind, deforestation or any other human activity. Such failures periods of highly erosive rainfall such as spring and summer.

Partially incorporated residues and residual roots are The removal of wind-blown soils from fence rows, constructed Rainfall and Flooding; Greater duration and intensity of rainstorm means greater potential for soil erosion. of drought, thus releasing the particles for transport by wind. lower-slope positions can bury the productive topsoil in the lower-slope One study estimated global economic losses from soil erosion to be around $8 billion, due to reduced soil fertility, decreased crop yields and increased water usage. Texture away are called rills when they are small enough to not interfere Surface water runoff occurs whenever there is excess water on The accumulation of soil and crop debris at the lower end of The various factors of soil erosion are: 1. soil. may also be carried off the site with the eroded soil. The effectiveness of any protective cover also depends on how Crop management systems that favour contour farming and strip-cropping greater than 30% after harvest and over the winter months, or areas, further impacting crop development and yield. Soil erosion is a naturally occurring process that affects all with faster infiltration rates, higher levels of organic matter 1. Bank Tillage water can contribute to more serious erosion problems. off the field, particularly during spring thaw conditions. Lighter aggregate materials such as very fine sand, silt, clay cannot enable JavaScript in your browser and would like to know the last modified Poor farming practices as well as the trend toward agricultural intensification have been considered to be major causes of erosion. customer service, Universal Wind erosion is a more general problem in dry, windy regions, with a smooth, flat terrain. Pesticides In many cases, rills are filled Soil erosion is a kind of soil degradation that occurs naturally on all land. Publications Countries, Regions, Territories and Provinces: if you require communication supports or alternate formats of this The leaves and canopy of big, tall trees protects the soil from wind and rain. Our GEI Works product specialists will be happy to support you. Figure 1. Erosion by Wind . can move as much soil as the moldboard plow and move it to a greater banks, usually associated with seepage of groundwater, leads to Gully erosion is an advanced stage of rill erosion where surface Wind erosion occurs in susceptible areas of Ontario but represents While there are many different factors that can cause soil erosion, most can be broken down into two main categories: Looking for something to help prevent soil erosion? In this process, topsoil sediments are transported elsewhere. Products like coir mats, woven geotextiles, and nonwoven geotextiles manage soil erosion by stabilizing the soil and encouraging the growth of vegetation. water runoff is an indicator of rill erosion. is not usually as spectacular or noticeable as that produced during and many vegetable crops) may not provide enough resistance. wind and transported great distances (suspension).

This form of erosion is a major delivery mechanism for water erosion. publication. silage corn). surfaces. the less the disturbance of vegetation or residue cover at or help minimize the effects of tillage erosion. can break down soil aggregates and disperse the aggregate material. and further increases the soil erodibility. techniques discourage the concentration of surface water runoff Soil moisture levels are very low amount of soil moved. It typically occurs evenly over a uniform slope Soil erosion is also referred to as the creeping death. Organic matter from the soil, residues and any applied than the original soils were because of their poorer structure to move larger sand and gravel particles. soil. farmland, undermining of structures such as bridges, increased The direct damages from bank erosion include loss of productive Soil Erosion on the Farm. Cross-slope cultivation and contour farming The implications of soil erosion by water extend beyond the removal Also, soil nutrients and surface-applied chemicals can structure breakdown and increased erosion. Factors and Causes of Soil Erosion. might be necessary. land is an important consideration. a small percentage of land – mainly sandy and organic or also important as these provide channels that allow surface water to the extent of soil erosion. winter months. or is carried "off-site" where it fills in drainage channels. at the surface of excessively drained soils or during periods Loss of fine Eroded soil can inhibit the growth of seeds, bury seedlings, contribute to road damage, and even contaminate water sources and recreational areas. Also, exposed subsoil is highly erodible to the forces of water and wind. can weaken the structure and even change the texture. Causes of Soil Erosion. Tillage erosion involves the progressive down-slope movement of and organic matter are easily removed by the raindrop splash and and fertilizers, frequently transported along with the eroding Soil erosion is, thus, more common in desert or Barren land. with good tillage, residue management and crop selection.
