calcSNUpE

Description

calculates the soil nitrogen uptake efficiency. This is the nitrogen taken up from the soil (N in crop biomass minus biological fixation minus seed N) divided by the soil N inputs (fertilizer, manure etc). For the future, SNuPE scenarios are added.

Usage

calcSNUpE(max_snupe = 0.85, cellular = FALSE, rev = 0.1, maccbase = TRUE)

Arguments

max_snupe	Maximum realistic SNUPE. All values above will be limited to this value. Only holds for past values; future scneario values can exceed this number.
cellular	disaggregated to 0.5 degree grid
rev	revision number of madrat run
maccbase	whether future scenarios should be expressed as base efficiency, excluding additional macc improvemetns (new default)

Value

List of magpie objects with results on country level, weight on country level, unit and description.
