Nitrogen nutrition status of the vine: correlation between N-tester and SPAD chlorophyll indices
Knowledge of the nitrogen nutrition status of the vine is essential for long-term management of its nutrition with the aim of producing high-quality grapes. Measurement of the chlorophyll index is a fast, non-destructive and relatively inexpensive method that provides a good approximation of the ni...
