Local and current soil nitrogen (N) mineralisation should guide supplemental N rates. To facilitatethis, methods for rapid assessment of crop N uptake (kg N/ha) were tested in five winter wheat(Triticum aestivum L.) trials in Sweden, around GS39. Four types of measurements were done:leaf sensors, handheld canopy sensors, multispectral drone cameras, and other, manual methods.Several options were found to be simple and accurate enough (mean absolute error
