As soil erosion is an ongoing problem across the world, it’s more important than ever to find effective solutions for soil erosion to deal with the problem properly.
Unfortunately, soil erosion continues to be an ever-growing environmental problem, one which needs to be taken seriously, as it poses a real and huge threat to water quality, agricultural productivity, and the health of the overall ecosystem.
It is more important than ever that efficient solutions to soil erosion are found. While it cannot be understated that soil erosion poses a significant threat to the environment, there are, thankfully, many solutions available to countries to utilise in their battle against it.
By implementing these strategies, important soil resources can be preserved and agricultural productivity maintained as well as importantly protecting our ecosystems. This article will list what we believe to be the top five best solutions for soil erosion.

TMTGN’s interesting facts about soil erosion:
- Soil erosion refers to the erosion of the top layer of dirt known as topsoil.
- Heavy rain, floods, storms, poor drainage, deforestation, farming practices, and harsh winds are some of the main causes of soil erosion.
- Gully erosion is a widespread and often serious form of soil erosion that is caused by flowing surface water.
- Take a look at these erosion control methods to learn how to avoid land degradation and soil erosion.
5. Terracing – a traditional farming practice
Terracing is a traditional farming practice and is especially important in areas such as mountainous regions as it aids in transforming slopes into a series of steps.
The technique of terracing helps to reduce the amount of water runoff and also allows more time for the soil to effectively absorb water and reduce the overall amount of erosion.
Terracing also helps to create flat surfaces perfect for farming, which in turn makes the land a lot more productive. Farmers will often build terraces along steep slopes for the best outcome.
4. Agroforestry – trees can act as very effective windbreakers
Agroforestry is a process which involves the cultivation of crops and trees on the same patch of land. As trees can act as very effective windbreakers, they help keep roots anchored to the soil, which prevents it from being washed away by water.
Other benefits that trees provide are shade as well as helping to reduce evaporation, and moderate soil temperature. By planting permanent vegetation, rain is intercepted, reducing and preventing splash erosion.
3. Mulching – reduces erosion by protecting the soil
Mulching is a process which involves applying a layer of organic or inorganic materials on the surface of the soil.
Mulching helps to reduce erosion by protecting the soil from the impact of rain as well as reducing water runoff and acting as a barrier to wind erosion.
Mulch also aids with conserving soil moisture as well as contributing to overall soil fertility as organic mulches tend to decompose.
For proper mulching, it’s best to remove any vegetation and even grade the area so that it drains in the preferred path.
2. Planting cover crops – protects soil from wind and water erosion
Planting cover crops helps to protect soil from both wind and water erosion. Cover crops such as rye and clover are ideally planted during off-seasons.
These plants not only cover the soil surface but also improve it by increasing organic matter as well as enhancing its overall water-holding capacity.
1. Crop rotation – a practice which helps to reduce soil erosion
In first place on our list of what we believe to be the top five best solutions for soil erosion is crop rotation, which is a process that involves the systematic planting of different crops in the same area across a variety of growing seasons.
The practice of crop rotation helps to maintain soil fertility and structure as well as reduce soil erosion.
Specific crops such as legumes can actually help to bind the soul together, which will strengthen the soil, making it much less likely to be blown or washed away.
That concludes our article on what we believe to be the top five best solutions for soil erosion.
While soil erosion presents a serious challenge, by understanding the importance of soil conservation and taking the correct steps to prevent soil erosion, we can ensure that things change for the better.

Contour ploughing: Contour ploughing, or contour farming, as the name suggests involves ploughing along the contour lines of a slope with the aim of forming ridges of soil that can act as effective barriers against water runoff.
The practice of contour ploughing is a favoured method against soil erosion as it helps to slow down the flow of water that can occur during heavy rainfall.
Rotational grazing: When livestock constantly graze in the same area, it comes as no surprise that the soil and area will degrade. As such, avoid overgrazing with rotational grazing, a great solution to soil erosion.
Conservation tillage: Conservation tillage involves minimal soil disturbance as it requires you to leave previous crop residue on fields both before and after planting the next crop.
The practice of conservation tillage reduces runoff and improves soil’s water retention which in turn helps to protect the soil from erosion.
Riparian buffers: Establishing riparian buffers along bodies of water is important as it helps to prevent soil erosion thanks to the fact that it filters runoff and anchors soil.
These vegetative buffers mainly tend to be composed of shrubs, trees or grasses and can quite significantly reduce the overall amount of sediment that is able to penetrate waterways.
Your questions answered about this topic
In this section, we answer some of our readers’ most frequently asked questions, including some that appear often in online searches on the topic.
What are the three major causes of soil erosion?
There are many causes of soil erosion, with the three most prominent types of soil erosion being water, gravity and wind.
Why is it important to stop soil erosion?
It is very important to stop soil erosion because the loss of fertile soil can make land less productive for agriculture as well as pollute waterways, amongst many other things.
What is a solution for soil erosion during a drought?
A great solution for soil erosion during a drought is to establish new ground cover as quickly as possible by planting quick-growing plants, which aid in preventing further soil loss while also helping to replenish lost nutrients by fixing nitrogen in the soil.
