Calculate NUEcrop
Description
The fraction of fertilizer N that is utilized and allocated to yield N. Calculate NUEcrop using the formula: NUEcrop = YieldN/FertN
Usage
NUEcrop(YieldN, FertN)
Arguments
YieldN |
A numeric vector of the N removed as yield values. |
FertN |
A numeric value for fertilizer N input. |
Value
The calculated NUEcrop value.
