Abstract
A liquid fertilizer system is used with agricultural implements to apply liquid fertilizer, in a desired amount, to a field and/or crop. The fertilizer system relies on system pressure to regulate the flow of the liquid fertilizer through and out of the system. The pressure is regulated, at least in part, by a motorized relief valve, which may be a pressure regulator that is modulated with a spring. The spring provides a nuanced adjustment mechanism that responds quickly to changes, and which is responsive to more minute changes to the system.
