THE VALUE OF INFORMATION FOR VARIABLE RATE NITROGEN APPLICATIONS: A COMPARISON OF SOIL TEST, TOPOGRAPHICAL, AND REMOTE SENSING INFORMATION

Abstract

We explore the value of soil test, topographical, and remote sensing information for guiding variable rate fertilizer applications in corn. Results suggest combining topographical and remote sensing information is more valuable than conventional soil tests. Considered separately, topographical and remote sensing information is not always as valuable as soil tests.Crop Production/Industries,
