Purpose - To describe the function and use of the GreenSeeker™ active remote sensor used to detect crop nitrogen status. Design/methodology/approach - In this paper, the GreenSeeker active remote sensor and its use in irrigated maize production systems will be described. A brief discussion of the science of using remote sensing for studying plants is presented. Additionally, a summary of observations collected from field trials is presented. Findings - The GreenSeeker active sensor has tremendous potential for accurately characterizing crop variability for site-specific N rate determinations in the Western Great Plains region of the United States. Originality/value - This paper discusses the GreenSeeker active sensor for detecting crop variability. Data from the GreenSeeker can be used to make site-specific nitrogen fertilizer applications which may lead to improved nitrogen use efficiency.
