The use of urea-ammonium nitrate (UAN) fertilizers is a crucial topic for most farmers. In this article, we will explore the types of flexible tanks suitable for the safe and long-term storage of UAN.
Why Choose UAN?
The key advantage of UAN lies in its composition, which includes three forms of nitrogen:
- Amide
- Nitrate
- Ammonium
These nitrogen forms are absorbed by plants gradually, depending on air temperature. This makes UAN a versatile fertilizer that nourishes both the leaves and root system, ensuring a balanced and prolonged effect. Farmers benefit from its extended absorption, leading to steady and efficient crop growth.
Another important advantage of liquid UAN fertilizers is their even application to the soil compared to granular and solid fertilizers. UAN can also be mixed with other pesticides and nutrients in a single tank, simplifying the fertilization process.
Choosing the Right Storage Tank for UAN
Farmers often prefer to purchase fertilizers in bulk during the off-season when prices are lower, sometimes by as much as 50%. However, this creates a storage challenge, as large volumes (100–200 m³) require specialized tanks.
Traditional UAN Storage Tanks
UAN storage tanks are typically made of plastic or metal. However, new models come with a high price tag, making them unaffordable for many farmers. Using second-hand tanks is also not the best option, as many manufacturers advise against storing fertilizers in containers previously used for other substances. Even after thorough cleaning, residue from previous liquids can affect fertilizer quality, soil health, and crop yields.
Flexible Tanks for UAN
A more practical solution for UAN storage is flexible tanks made of technical fabric coated with elastomers. These mobile and collapsible reservoirs are far more compact than traditional stationary tanks. They can be installed on any surface without the need for a foundation or heavy machinery. When not in use, the tank can be folded and stored in a compact box.
Additionally, textile tanks cost several times less than their metal or plastic counterparts.
The experience of European countries such as France, Germany, and the Netherlands demonstrates that using flexible tanks for fertilizer storage, including UAN, can reduce farm expenses by up to 30%.
Ensuring Safe and Efficient Fertilizer Storage
The safety and effectiveness of fertilizer use directly depend on the quality of storage solutions. By choosing certified UAN tanks that meet European standards, you can avoid unforeseen expenses and operational risks.
You can purchase high-quality UAN storage tanks exclusively from Flexsol — a manufacturer that produces its products using advanced high-frequency welding (HFW) technology. This ensures financial security, reliability, and warranty service for your storage solutions.
