Fertiliser Silos

Ahrens is the Number 1 name when it comes to rural infrastructure for agriculture industries in Australia, and the range of Ahrens transportable silos lead the way when it comes to durability, service and ease of end-customer use. 

With a range of features to suit storage of all types, and a five-year warranty, you can be sure that your equipment will last your for many harvest seasons to come.

Safe Fertiliser Storage Facilities

Fertiliser storage can be a crucial issue for some farms, where fertiliser has been purchased in bulk and needs to be protected from the elements and contamination, but also from igniting or contaminating other farm products or even other fertilisers. 

A fertiliser silo is a great way to protect your fertiliser and Ahrens transportable silos are suited for the storage of nitrogen fertilisers, phosphate fertilisers and potassium fertilisers. 

Unlike grain silos, fertiliser silos require some additional precautions in order to ensure safe storage, with Ahrens fertiliser silos including a corrosion-resistant base coating, extended legs and stainless steel parts in order to ensure the highest corrosion protection. 

These silos are available in sizes from 4 tonnes to 75 tonnes, and are made with the highest-quality Australian materials, and are designed to meet a range of industry standards, specifications and requirements in all agricultural applications.

Gas Lock sealed silos prevent moisture from entering the silo, and are the best option for nitrogen fertilisers, as they need to be kept in a secure building in a cool dry place, away from any combustible materials or moisture. 

Temperature control is also vital when it comes to the storage of volatile fertilisers such as nitrogen. Fertilisers are also typically denser than grain, which requires a silo made of sturdier construction than a grain solo, with thicker material usually required for optimal performance.

Transportable Fertiliser Silos

Ahrens’ fertiliser storage silos – or transportable fertiliser silos – are available in a range of sizes from 56 tonnes to 82 tonnes and are delivered fully assembled and ready for immediate use.

These transportable fertiliser storage systems are flexible, and can be designed as one individual silo or as larger-scale complete fertiliser storage systems, depending on your specific needs for capacity, size and the number of required silos.

Ahrens Rural transportable are gas sealed in accordance with AS 2628-2010, and protects your stored product by preventing any moisture, sunlight or contaminants from entering the silo.

Base Construction and Accessories

Zincalume® Steel Construction

For the best strength, durability and performance in Australian conditions, Ahrens transportable silos’ sidewall and roof construction is made from genuine Australian-made Zincalume® steel.


Fully Welded and Galvanised Base

Ahrens transportable silos feature a fully welded – internal and external – galvanised base construction, with a 45-degree cone.

Gas Sealed and Pressure Tested

Ahrens transportable fertiliser silos are gas sealed and pressure tested in compliance with Australian Standards AS 2628-2010, and feature a valve for air pressure release and monitoring and a 600mm diameter ground-operated pressure sealing centre fill with a stainless steel cabling hand winch.

Industry Leading Footing Design

These silos feature an industry-leading footing design, which incorporates 5mm tie-down plates and 16mm blocks under the silo base ring, enabling sufficient clearance for drainage at the bottom of the silo, and adequate site hygiene, as well as the AnkaScrew™ 150mm x 12mm connection to the concrete platform (concrete foundation to be supplied by the customer or client prior to silo installation). 

The AnkaScrew™ is ideal for temporary anchoring to concrete or brick, and does not expand or burst the substrate, able to be removed and replaced before and after transport.

Silo Slight Glasses

To enable ease of inspection of your grain levels or grain silo interior, Ahrens transportable silos include sight glasses. 

These allow examination of the interior of your silo, without having to break the gas seal.

The sight glasses are fitted at multiple heights along the side of your silo to allow for accurate estimation of the grain levels, and better observation conditions.

Tips on How to Store Fertiliser

There are a number of fertilisers used by farmers in Australia. These include nitrogen-based fertilisers, such urea, manure and other bio-fertilisers made from animal urine and dung; phosphate-based fertilisers or superphosphates, including diammonium phosphate and monoammonium phosphate; and potassium-based fertilisers such as potash, typically used in lower quantities; as well as a range of combination fertilisers covering a range of required minerals, such as NPKs and SSPs.

These different types of fertilisers come with their own storage challenges and requirements, and it is important to do your research before making any bulk purchases.

Fertiliser Storage Methods

When it comes to farm storage of fertilisers there are several methods people use to protect the product when not in use.

Fertiliser Storage Sheds

Fertiliser sheds allow for fast fertiliser storage ahead of sowing time, and reduces the time it takes to access the fertiliser when quickly needed, while protecting the product from exposure to the elements, most importantly rain, UV and sunlight. 

While an effective short-term method, fertiliser sheds don’t provide the same level of protection that a fully sealed tank or silo does, and can still allow water found in the air or contaminants to enter the stored product, which could result in loss of nutrients or chemical imbalance.


Fertiliser Storage Tanks

Fertiliser storage tanks are a smaller but more effective method of storing chemicals than a storage shed, without sacrificing too much by the way of access time, and are typically the cheapest option. 

They are held back though by their lack of pressure or temperature control, and may lack the required properties for application in the storage of harsher or more corrosive chemicals due to the lack of coatings.


Fertiliser Silos

Fertiliser silos are the most heavy-duty storage option, allowing for epoxy coatings, paint and sealers that protect the fertiliser from outside influences. 

The ability to gas seal these products is the best option when it comes to harsher and more volatile fertilisers, and can serve their purpose for many years, without impacting farm safety or product quality. 


Safe Fertiliser Storage

When storing fertiliser on your farm or property, it is important to ensure that you are doing it safely, and in accordance with all relevant state, national and local regulations and requirements. 

Fertiliser Storage Regulations

There are a number of regulations in place for the safe storage, transport and application of fertilisers on an international, federal, state and local level, and it is important that you know what these regulations are before storing fertiliser on your farm.

For more information on how you should handle and store fertiliser on your property, contact your local or state government for the applicable laws, acts and regulations.

Many fertiliser companies also offer literature or information on how to store your fertiliser correctly, and may be able to provide information about your local requirements.

Fertiliser Storage Requirements

Different fertilisers have different storage requirements based on their volatility, flammability and ability to cause environmental damage if they spread or leak into waterways. 

There are many types of fertilisers on the market that are restricted by law and only able to be sold to farmers and other professional users in order to prevent misuse, and reduce the risk of contamination or injury.

Check with your provider, manufacturer and local government to ensure you are meeting your storage and usage requirements.
