Publication number: 20190285608Abstract: An apparatus, method, and system for on-the-go soil nitrate level sensing, and optionally using the sensing to inform or instruct nitrogen fertilizer application across the field. In one form, the apparatus includes a soil sensing tool which carries a diamond ATR cell in combination with an FTIR field ruggedized spectrometer. The optical surface of the diamond ATR cell can be adjusted in pitch and depth to the soil. A processor is programmed to manipulate acquired spectra to derive a prediction of nitrate level for a given soil position in the field. This can be used to modulate a fertilizer applicator operation or coupled with georeference data collected simultaneously to generate a map of soil nitrate levels for the field, which can be used as a prescription for nitrogen fertilizer application.Type: ApplicationFiled: May 17, 2019Publication date: September 19, 2019Inventors: David Laird, Natalia Rogovska, CHIEN-PING CHIOU
