“Our firm has been working toward
zone management since 1994 — using
all the tools (soil testing, tissue testing,
yield and planting data, soil type, etc.)
available to decide on an appropriate
course of action for a fertilizer
prescription, be it soil- or foliar-
applied. And while the 4R concept
may be simple, implementing the
systems needed to practice it can
be challenging and costly”
