Abstract
In order to realize on-the-go site-specific management of nitrogen for agricultural and turf grass operations, the need for a rapid, robust methodology for measuring plant nutrient deficiencies is required. Crop canopy reflectance sensors that are currently available are limited primarily by the need for adequate ambient light (sunlight) in order to make the required measurement. The proposed research will develop and prototype a new sunlight independent light sensor which will measure the color spectra reflected from plant canopies and/or soil. The sensor will be integrated into a network of sensors that are connected to a central data collection and control instrument. Data collected from the sensors will be utilized in determining the nutrient requirements of the plant material or for determining the organic matter content of bare soil. The new sensor will overcome the sunlight irradiance limitations by actively irradiating the plant or soil with an integrated light source. The new sensor will be able to make measurements in full sun or in complete darkness.
