Liquid Potash 28-0-0-26S Storage — Potassium Sulfur Fertilizer Tank Selection

Storing Liquid Potash 28-0-0-26S? Start Here

Liquid Potash 28-0-0-26S is a versatile potassium-sulfur fertilizer used in various agricultural applications. It's a clear to pale amber liquid that combines potassium chloride with thiosulfates to deliver essential nutrients. This fertilizer is ideal for fertigation, banded, and in-furrow use. However, it has a crystallization point between 18 and 22 degrees F, so cold weather storage requires some attention. The solution is non-hazardous for transport, but it’s crucial to consider chloride content when planning crop rotations.

Can you store it in a poly tank?

Yes, you can store Liquid Potash 28-0-0-26S in a poly tank. Polyethylene tanks, including HDPE and XLPE, are suitable choices for this fertilizer. They handle the chloride content well and are ideal for both storage and primary piping. Avoid using stainless steel or carbon steel as primary contact surfaces due to corrosion risks.

Watch Out for Cold Weather Crystallization

One key issue with storing Liquid Potash 28-0-0-26S is its tendency to crystallize in cold weather. If you're in a colder climate, consider draining tanks to a heated indoor location or maintaining a freeboard of over 6 feet with circulation to prevent crystallization at the suction strainer.

The safety that actually matters

• Ensure tanks are well-ventilated to prevent pressure build-up.
• Use appropriate gaskets, like EPDM, to avoid leaks.
• Regularly inspect tanks and fittings for signs of wear or damage.

Common questions

Can I use this fertilizer with all crops?

Be cautious with sodium-chloride-sensitive crops like tobacco and certain berries due to the chloride content.

What type of pump should I use?

Use polypropylene-bodied centrifugal or stainless-trim diaphragm pumps for best results.

How do I prevent crystallization in cold weather?

Store tanks indoors or ensure proper circulation and freeboard to prevent salt-out.
