AST vs. UST: Which Liquid Fertilizer Tank Should You Choose?

Liquid Fertilizer TanksThere are different kinds of fertilizer tanks and choosing a liquid fertilizer tank, for instance, can be a simple task if you know what will serve your own needs best. Liquid fertilizer tanks are important to any kind of agricultural work — or basically any work that needs liquid storage. It needs regular maintenance for it to function properly.

Here are some of the well-known types of liquid fertilizer tanks and their pros and cons to help you decide:

Aboveground Storage Tanks (AST)

Manufacturers build ASTs above the ground, as its name suggests. They build it either on a stand or a ground pad. These tanks are ideal for storing bulk fuels, agricultural chemicals, and other liquid substances. ASTs are less costly to build, making them a cost-efficient option for many businesses.

ASTs are subject to strict state and federal regulations, however, so it’s important to keep these tanks well maintained. It’s important that you choose a material that’s corrosion-resistant because of the highly toxic nature of the liquids they contain. Lightweight tanks with maintenance-free exteriors and don’t conduct electricity, for example, are good choices.

Underground Storage Tanks (UST)

Manufacturers build USTs, but they only let 90% of its mass go below the ground. They make sure that there’s still space above the ground (10%) to make the tanks easier to identify.

Many companies choose this type of tank for storing fuel, like petroleum. The cost of USTs is higher compared to ASTs because of the nature of the tank and the need to excavate during construction.

No matter what tank you choose, their contents may still pose an environment threat. Both AST and UST are durable, but they can be prone to leakage without proper maintenance.
