Leaf nitrogen determination using non-destructive techniques–A review

M. M. Ali, Ahmed Al-Ani, Derek Eamus, Daniel K. Y. Tan
2016 Journal of plant nutrition  
Destructive methods are expensive and timeconsuming as they require tissue sampling and subsequent laboratory analysis. Thus, many farmers find destructive methods to be less attractive.  ...  The optimisation of plant nitrogen-use-efficiency (NUE) has a direct impact on increasing crop production by optimising use of nitrogen fertiliser.  ...  Fairly large nonlinear relationship between leaf chlorophyll content and chlorophyll meter values allows calculation of a unitless "SPAD" value (on an index from 1 to 100).  ...
