The use of liquid fertilizer in the field crop industry is increasing rapidly. The bulk storage of liquid fertilizer requires primary and secondary containment features as specified in MDARD Regulation No.642.

The use of liquid fertilizers, particularly in the field crop industry, has sharply increased in the recent years. Liquid fertilizers are easier to custom blend and use as starters, pop-ups, broadcast spray, sidedress or foliar applications. As a result, Michigan Department of Agriculture and Rural Development (MDARD) estimates that Michigan will have more than 80 million gallons of bulk agricultural storage space in 2013. This is a 35 percent increase from 2012.
