Recent interest in micronutrients, such
as boron, has farmers curious about
yield impacts of in-season, foliar applications
of these micronutrients to
• Duane Johnson compared soybeans
that received a foliar application of boron
with those that received no boron.
• There was no measured effect of foliar
boron fertilizer on soybean yield, thus
the cost was not warranted.
