Alley Cropping (Agroforestry) – Planting trees among agricultural crops helps to protect the soil from erosion, particularly after crops are harvested. The trees will give some protection from rain splash. Fruit, trees, legume trees for fodder or firewood and alley cropping all help reduce soil erosion.

How does class 7 prevent soil erosion?

Prevention of soil erosion can be done by (i) afforestation that is large scale planting in place of cut down forests. (ii) avoiding overgrazing of grasslands. (iii) terrace farming and other better farming methods in hilly areas.

What is soil erosion and its prevention?

It is the natural process of wearing away of the topsoil, but human activities have accelerated the process. It is usually caused due to the removal of vegetation, or any activity that renders the ground dry. Farming, grazing, mining, construction and recreational activities are some of the causes of soil erosion.

How to reduce soil erosion?

Reduce tillage. Deep, frequent tillage creates a layer of compact soil vulnerable to water erosion, topped by loose soil easily removed by wind. Consider a zero- tillage approach using a coulter or other deep planting device.

How to protect weak crops from erosion?

Crops with weak roots or that need to be sparsely planted are more vulnerable to erosion. Plant these in strips, alternating with strips of an erosion-resistant crop such as dense grass or legumes.

How to prevent erosion in farmland?

For a quick erosion fix, add mulch or rocks to weigh your soil down. If you have a steep slope, try mulch matt for a secure option . Prevent long-term soil erosion by covering the bare ground with turf, ornamental grass, or spreading shrubs. Avoid walking over your soil, which can lead to further erosion. For advice from our Gardener about how to prevent farmland erosion, read on!

How does erosion affect the food production capacity of the land?

Erosion leads to the loss of topsoil and critical nutrients. Over time this will reduce the food production capacity of the land.

How to stop erosion on a steep slope?

Put down fiber logs. Another option for erosion control on steep slopes is a series of rolled up logs or “wattles” made from fibrous material (like straw). Water running down the slope will slow down when it hits the logs, soaking into the soil instead of carrying mud downhill. Put the logs down across the slope, 10 to 25 feet (3–8m) apart. Hold them in place with wooden stakes or sturdy, living plants.

Why do plants use nutrients?

Plants use nutrients from the soil to grow . The more plants there are, the more nutrients get used up. After a while, the soil loses its nutrients and becomes unusable. Since plants are the most effective way to hold soil together, over-farming can make erosion much worse.

What to do if you don’t plant anything?

If you don’t plant anything, keep the soil covered with mulch. You can also add mulch around plants to add another layer of protection or to keep the soil warm. Note: If you plant something in the soil, the plant’s roots can hold the soil together, and you may not need mulch or rocks. …

How to prevent soil erosion?

1. Plant Cover Crops. Cover cropping allows plants to continue to grow in the off-season, providing the soil with more nutrients to strengthen it. They are planted between crops you traditionally plant for yields. It’s both a regenerative agriculture practice and a known practice for reducing soil erosion.

What are some ways to prevent erosion?

Build Water Diversions. There are a few types of erosion, one of them being from runoff. When a heavy downpour hits, soils that are dry or lack nutrients can be swept away by running water. If you struggle with erosion due to water, build water diversions.

What crops do large corporations plant?

Many large agricultural corporations plant a ton of corn and soybeans. These are essential products for much of the food and other items you see in the store. However, a lack of variety strips the soil of its integrity and nutrients.

How does mulch help with erosion?

Mulch locks in moisture and adds extra nutrients to your topsoil as the mulch breaks down. This both prevents erosion and regenerates the topsoil. 10. Contour Farm. Instead of planting crops in straight rows, follow the natural lines provided in the landscape.

What is the purpose of planting trees around your fields?

Their leaves slow down the force of the wind. Planting a row of trees around your fields acts as a windbreaker, which can prevent topsoil erosion on bare fields. You could also plant crops in between already-existing rows of trees, which is called agroforestry.

How has erosion happened?

Erosion has happened since the earth formed. It’s a natural process that occurs over time. Traditional farming practices, like heavy fertilization and over-tilling, have progressed the degradation of soil health and have caused further erosion over the years.

Why is integrating livestock in your crops important?

Similar to managed grazing, integrating livestock in your crops allows for natural nutrient cycling. The separation of animals from crops has increased pollution, risked animal health, and led to improper disposal of manure.

How to reduce 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.

What is the effect of soil erosion on the world?

Uncontrolled rates of soil erosion around the globe are depleting fertile and healthy topsoils at unprecedented rates.

Why is soil important to the environment?

Healthy soils make our world go round. They’re not only the backbone of the agricultural system we rely on for countless foods and materials but also provide environmental services crucial for a healthy water cycle, climate, and ecosystems. Unfortunately, soil erosion around the world is leading to mass degradation of soils leaving farmers and ecosystems alike in trouble. This leaves many starting farmers wondering, what can farmers do to reduce soil erosion?

How do agrochemicals affect soil?

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. Many fertilizers deplete your soil’s organic matter, while pesticides can dramatically alter your soil food web.

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 much soil will be degraded by 2050?

The UN Symposium on Soil Erosion estimates that by 2050 we may degrade more than 90% of all soils!

What causes soil erosion?

Several farming practices can lead to erosion. When farms are created and native plants are removed, topsoil is left vulnerable. Overgrazing, tillage and heavy fertilization can also lead to crop fields eroding. While farming is a large contributor to the loss of topsoil, agriculture is absolutely necessary to feed our world.

Means of soil erosion

When most people think in terms of erosion they are often envisioning creeks and rivers overflowing, torrential downpours and other causes of flooding. While it is true that water is the largest factor, wind plays a very important role.

Prevention

There are many ways to reduce yard, garden or field plot eroding, and most are quite simple. Slowing down the effects of natural elements, such as wind and heavy rain, is important.

What are the practices used to control soil erosion?

Agronomic, cultural, or structural practices are available for controlling soil erosion. Structural practices involve physical changes in the shape and topography of the land. All these practices are not mutually exclusive. Some situations may require both management and structural changes, where the topography is highly complex.

How does soil conservation affect erosion?

The amount and rate of surface runoff can affect erosion and sediment transport. Thus, soil conservation practices are important in reducing soil erosion. 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 …

What is the difference between rill erosion and ephemeral erosion?

Rill erosion occurs during heavy rains, when small rills form over an entire hillside, making farming difficult. Gully erosion makes gullies, some of them huge, impossible to cross with farm machinery. Ephemeral erosion occurs in natural depressions.

Why is soil erosion bad?

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. The problem may become so severe that the land can no longer be cultivated and must be abandoned. Many agricultural civilizations have declined due to land and natural resource mismanagement, and the history of such civilizations is a good reminder to protect our natural resources.

How is sediment transported?

Eroded topsoil can be transported by wind or water into streams and other waterways. Sediment is a product of land erosion and derives largely from sheet and rill erosion from upland areas, and to a lesser degree, …

Why is Iowa losing soil?

Soil losses in Iowa due to water erosion and surface runoff can contribute a great deal to surface water quality concerns. Many studies indicate that soil erosion results in large decreases in soil productivity.

How does erosion affect water quality?

The 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. Several conservation practices can be used to control erosion but first you need to understand the factors affecting soil erosion. Soil erosion is the detachment and movement of soil particles from the point of origination through the action of water or wind. Thus, minimizing the impact of water or wind forces is the main objective for erosion control. Water erosion is the most pertinent erosion problem in Iowa.

How does soil erosion affect agriculture?

What is the cause of soil erosion?

One of the leading causes of soil erosion is deforestation. Although incredibly bad for the environment, the slash-and-burn technique has become a popular method of clearing forest areas, often for use in agriculture. However, this method leaves areas vulnerable to soil erosion by wiping out the trees whose roots helped keep …

Why is organic farming important?

Switching to organic farming methods is being encouraged in the agricultural sector not only to reduce soil erosion and product crop yields but also for the other numerous environmental and health benefits it brings.

Why do farmers switch to row crops?

Also, there has been a recent trend in the US for farmers to switch to certain row crops, like corn, because its value has doubled, while its susceptibility to soil erosion is putting entire farms at risk of financial failure.

What are the factors that contribute to soil erosion?

Another major factor contributing to soil erosion is climate change .

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 many hectares of land are abandoned each year?

Studies have shown that around 10 million hectares of land are abandoned each year due to this lack of crop productivity caused by soil erosion. This effects some regions more than others, with Africa, Asia, and South America averaging at a loss of 30 to 40 hectares annually.
