Pop-up liquid fertilizer is a great way to increase corn yields and reduce early stress on corn development. Pop-up starters at the 3-to-5 gallon rate/a allow nutrients to be placed directly on the seed.
However, no sulfur should be included with a pop-up fertilizer. In a two year study at the Agronology 10 Research Center at Walcott, IA, average corn yields were increased from 206.6 bu/a to 214.0 bu/a with a 5 gallon/a rate of 6-24-6 pop-up fertilizer.
