sNBI: Calculate N Balance Index of a System (sNBI)
In NUETON: Nitrogen Use Efficiency Toolkit on Numerics
sNBI R Documentation
Calculate N Balance Index of a System (sNBI)
Description
The accumulation or reduction of soil N over a set time.
Formula: sNBI = Ni - No - delSoilN
Usage
sNBI(Ni, No, delSoilN)
Arguments
Ni
Sum total of N inputs (vector or value).
No
Sum total of N outputs (vector or value).
delSoilN
Change in total soil N value.
Value
A numeric vector of sNBI values.
Examples
Ni <- c(100, 120)
No <- c(80, 90)
delSoilN <- c(5, -2)
sNBI(Ni, No, delSoilN)
