How Late Can You Apply Nitrogen and Still Get Yield Increase?

June 02, 2016

One of nitrogen’s (N) defining attributes is that it’s easily lost in wet weather conditions.

Which means if you're having a wet season, you may be short on N by the time V8 and VT come around—the window of time that corn takes up half it's N supply, and which only lasts for approximately 30 days.

It's for this reason so many farmers choose to do their sidedressing by V6. Your crop will have N reserves available for V8, and you won't need high-clearance equipment to get the job done. 

But what happens if you need to sidedress after V6? You may be able to get a hold of high-clearance equipment, but will extra N during tasseling time actually help you hit your yield goal? Or even exceed it? 

In the short video below (2 minutes), Tracy Blackmer, Vice President of Science at FarmLogs, reveals what happened when one farmer, during a very wet season, decided to add 50lbs of nitrogen to his field during tasseling time.

This talk was originally presented at the 2015 FarmLogs User Conference.
