Managing nitrogen as a system aids yields and environment
Henry Shepard knows it’s important to apply enough nitrogen so his corn fields can reach maximum yields. A few years ago, as part of a government conservation program, he sharply trimmed nitrogen applications on some of his fields near La Porte City and saw his corn yields tumble.
But Shepard is also concerned about applying too much nitrogen because the excess nutrients won’t be utilized by the corn. That wastes money and has the potential to negatively impact the environment.
