Sammanfattning

Local and current soil nitrogen (N) mineralisation should guide supplemental N rates. To facilitate
this, 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 <5 kg N/ha)
for practical use by farmers and advisors. The best results were obtained when leaf and canopy
measurements were combined.
