AMVAC offers an after-market system that can be added to the planter, giving the farmer the ability to prescriptively apply multiple dry or liquid products while planting. Jim Lappin oversees the SIMPAS portfolio and uses iron chlorosis in soybeans as an example. “Those areas don’t move a lot from year-to-year, but they don’t affect the whole field,” said Lappin. “Does it make sense to spread incremental iron across the whole field when it only affects certain zones within the field?” Lappin sees an opportunity for growers to save input costs or invest in other yield-limiting agronomic issues within the field.
