The efficient management of Nitrogen (N) is a challenging issue, and a range of individual and collective solutions are utilized to control it. Sadly, as predicted by the researchers when creating nitrogen management tools and procedures, nitrogen use efficiency (NUE) has not improved to a level of just 33%. Several approaches, including soil testing, spectrum response, fertilizer distribution and timing, and vegetative indices (leaf area index, and NDVI) employing drones, portable sensors, and satellite imaging, were investigated about the user-friendliness and effectiveness of NUE. It was found that no single method could completely stop the nitrogen leak. Plant tissue testing was one of the procedures found unsuited to a particular crop’s N absorption behavior.
