The short version
What Beck’s set out to test
The purpose of this study is to evaluate utilizing a drip-irrigation system to apply nitrogen and sulfur compared to Beck's standard sidedress application.
What they found

The only difference in the treatments is the method of application. The control received the same amount of water and total pounds of N. The drip line is on 30 in.
