Use N Resorption Efficiency when you need to compute nitrogen resorption efficiency in percent as (green leaf N - senesced leaf N) over green leaf N times one hundred. Enter Green leaf N and Senesced leaf N using the definitions and units below so the result can be reproduced.

Green leaf N

A finite measured or assumed value greater than or equal to 0, expressed in mg/g.

Senesced leaf N

A finite measured or assumed value greater than or equal to 0, expressed in mg/g.

The published tool contract uses this rule: Compute nitrogen resorption efficiency in percent as (green leaf N - senesced leaf N) over green leaf N times one hundred.

Nitrogen resorption efficiency

The calculated nitrogen resorption efficiency in %.

The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.

Retain the original Green leaf N and Senesced leaf N values and their units alongside the result. P Resorption Efficiency is useful when you instead need to compute phosphorus resorption efficiency in percent as (green leaf P - senesced leaf P) over green leaf P times one hundred. PNUE provides another view by helping you compute photosynthetic nitrogen use efficiency PNUE in micromoles per mole as the net photosynthesis rate divided by the leaf nitrogen per unit area.
