A fertilizer application system for a liquid fertilizer concentrate includes a container containing a first fluid. A siphon is disposed on the container and includes two inlets and an outlet. A flow control valve is configured to selectively control an amount of first fluid flowing through the siphon based on ambient temperature of an environment outside the container. A siphon tube includes a siphon tube first portion in fluid communication with the first fluid, and a siphon tube second portion fluidly coupled to an inlet of the siphon. The first fluid includes a liquid fertilizer concentrate comprising a nitrogen containing source, a phosphorous containing source, a sulfur containing source, a potassium containing source, an iron containing source, and water.
