Importance of Topsoil – How to Apply it on Your Farmland?


Topsoil is an important factor in achieving successful crop growth and productivity. Familiarising farmers with the properties and characteristics of topsoil, such as nutrient content, pH levels and soil structure can enable them to be decisive. It helps them to be prompt in decision making regarding farm practices like irrigation, crop rotation, fertilisation and tillage. 

By keeping themselves updated on topsoil and implementing effective soil management practices farmers can ensure the long term sustainability of their land and prosperity of their farming practices.

What is TopSoil?

You might be curious about how topsoil is used, but that question can only be addressed once you have a clear understanding of its definition.

It is the uppermost layer of soil found on the surface of the earth that is highly valued by farmers for its exceptional abundance of nutrients, minerals, and organic matter. Topsoil is a blend of sand, silt, and clay. 

Exploring the Abundance of Essential Nutrients in Topsoil: This soil is rich in crucial nutrients, such as nitrogen, phosphorus, potassium, and magnesium, which are essential for maintaining soil fertility. 

Nitrogen promotes plant growth and encourages the healthy development of stems and leaves, whereas potassium and magnesium support photosynthesis and the growth of lush, green foliage. Phosphorus plays a vital role in building plant cells and DNA. 

Although these nutrients exist naturally in topsoil, their levels and quality may differ. By supplementing the soil with these nutrients, soil fertility can be enhanced, and soil structure can be improved.

How To Strike The Perfect Soil Ph Balance: For topsoil to be of good quality, it should have a pH level ranging from mildly acidic to slightly alkaline, typically between 5.5 and 7.5. This range is ideal for allowing crops to absorb the necessary nutrients from the soil. 

While most crops can tolerate a wide range of pH levels, soil that is too acidic or too alkaline can lead to issues. Maintaining a balanced soil pH level is crucial for promoting a healthy farm and avoiding potential problems.

This layer usually ranges from 2-8 inches deep. It is vital for the growth of various crops since it furnishes them with the requisite water, nutrients, and air.

This soil formation takes place over an extended period as rocks undergo chemical alterations and break down into tiny particles through weathering. 

During this process, a variety of organic materials such as vegetation, dead animals, and leaves naturally accumulate on the earth’s surface, ultimately mixing with the topsoil. It takes an incredibly long time for topsoil to form, usually 100 years. It is often combined with mulch too.

We are now prepared to address the next query that might be on your mind:

What Is Topsoil Used For?

Enhance Farm Drainage

Topsoil, which typically consists of a blend of sand, silt, and clay, has the potential to improve drainage in farms. This is because it aids in water retention and drainage, allowing water to pass through the soil quickly, preventing waterlogging, and enhancing drainage. 

Furthermore, the organic material found in it can enhance soil structure by decreasing compaction and increasing porosity, which can further boost drainage.

Improves Soil Aeration

As topsoil and its organic components integrate with the rest of the soil, they can diminish soil compaction and enhance overall drainage in the farm. Improved drainage allows for better distribution of water and oxygen to crop roots, promoting their healthy growth.

Kelly Tillage 8024 Diamond Harrow is the biggest model. It possesses a vast 24m width and a hefty 16,800kg frame. This model stands out in its ability to cover ground, working at a speed of 20-25 hectares per hour. When it comes to shallow tillage, it doesn’t get any bigger than this. Using this equipment will help in improving your topsoil aeration. 

Freshen Your Farm Look 

Topsoil contains nutrients and organic matter that provide a rich, dark colour to your farm. The harsh winter weather and unfavourable conditions can deplete the soil of its vital components, causing it to lose its lustre and become dull. 

To restore your farming area’s appearance, consider adding a fresh layer of topsoil. This simple solution will provide the necessary nutrients and organic matter to restore your soil, resulting in an overall enhanced appearance for your farm.

Enhance Your Plants’ Ability to Withstand Drought

It’s no secret that summers in Australia can be scorching. However, adding topsoil to your farming area can help safeguard your crop roots by retaining moisture that has already penetrated the soil. 

By preventing evaporation, topsoil ensures that there is ample water available for your crops, even during times of limited rainfall. This way, your crops can receive the moisture they require to thrive.

Reduce Erosion

In farming areas, topsoil plays a vital role in preventing erosion. Exposed soil can easily be eroded by natural elements such as wind and water, leading to nutrient depletion, reduced soil fertility, and other detrimental effects. 

Adding a layer of it can provide a protective barrier for the underlying soil, preventing erosion. The organic matter and nutrients found in topsoil can also promote healthy crop growth, which further protects the soil from erosion. 

Furthermore, it can improve soil structure, reducing the likelihood of erosion caused by water runoff.

Fixing Low Spots

Using topsoil to level any low spots on your farm is a great idea. Not only will this create a more visually appealing and level surface, but it will also help distribute water evenly and provide an idle environment for crop growth.

How to Apply Topsoil on your Farmland? A Guide

  1. Add three Inches of nutrient-rich topsoil to your seedbed to support your crops’ health and growth.
  1. After adding the topsoil to the seedbed, till it with the subsoil until you have a six-inch layer of mixed soil. This deep layer of soil will create enough space for your crops to establish strong root systems.
  1. The nutrients and microorganisms in the topsoil will gradually spread throughout your fields. To ensure a healthy farm, add organic material, mulch, and other soil amendments to it regularly.

The Kelly Tillage System Model 4614 is a highly sought-after machine due to its remarkable features. This machine can be equipped with an optional Kelly Seeder, making it ideal for seedbed preparation, establishment, and cover crop incorporation all in one go.

Final Thoughts 

To sum up, topsoil plays an important role in maintaining the earth’s ecosystem. It serves as a basis for crop growth, regulates water and nutrient cycles, and facilitates the existence of various microorganisms that are crucial for soil health. 

When buying topsoil, it is important to consider the ethical practices of your supplier. It is recommended to avoid suppliers who extract topsoil from virgin green fields, as this process can disrupt the ecosystem and take years to replenish. 

Instead, opting for topsoil sourced from cleared sites before development is a more environmentally conscious option, as it repurposes material that would otherwise go to waste.
