Estimating canopy nitrogen concentration of sugarcane crop using in situ spectroscopy

Estimating canopy nitrogen concentration of sugarcane crop using in situ spectroscopy

Estimating nitrogen (N) concentration in situ is fundamental for managing the fertilization of the sugarcane crop. The purpose of this work was to develop estimation models that explain how N varies over time as a function of three spectral data transformations in two stages (plant cane and first ra...
