Having liquid fertilizer tanks that are properly-functioning and well-maintained is an important part of any kind of agricultural work.

But it’s also a necessity to make sure you’re investing in the right kind of liquid fertilizer tank — as there isn’t just one, but two predominant types of tanks to be aware of. Knowing which type of tank you need for your workplace is essential to its overall success.

Here are just some of the most important things you should know about above ground storage tanks (ASTs) and underground storage tank constructions (USTs), and the ways in which they differ from each other:

Above ground storage tanks

As their name implies, above ground storage tanks are constructed above ground level. On occasion, they can be partially buried or located in a below-ground vault, but for the most part they are located above the ground on a stand or ground pad. These above ground tanks are generally more ideal for holding bulk fuels and chemicals, and are also less expensive than an underground storage tank, making them a more attractive cost-efficiency option. However, above ground tanks are subject to strict state and federal regulations, as well, making it important to keep these tanks well-maintained.

Underground storage tanks

Underground storage tanks are, obviously, buried underground and has at least 90% of its mass surrounded by ground. They are more typically used to store petroleum fuel and gasoline, as their underground locations make them an attractive option for high-traffic areas like a gas station. Because many USTs have leaked and caused petroleum to enter the groundwater, the environmental integrity of these tanks is often questioned.
