toolFertilizerDistribution: toolFertilizerDistribution

In pik-piam/mstools: Tool functions that can be used by several madrat-dependent or magpie4 output functions

toolFertilizerDistribution

Description

Disaggregates fertilizer usage, trying to best match a certain soil nitrogen uptake efficiency (SNUpE). Also used in magpie4 library

Usage

toolFertilizerDistribution(
  iteration_max = 50,
  max_snupe = 0.85,
  mapping,
  from,
  to,
  fertilizer,
  SNUpE,
  withdrawals,
  organicinputs,
  threshold = 0.5
)

Arguments

iteration_max	maximum iteration for downscaling
max_snupe	the maximum level of nue or snupe
mapping	mapping used for disaggregation
from	name of from column in mapping
to	name of to column in mapping
fertilizer	total inorganic fertilizer to be distributed on regional leve
SNUpE	Nitrogen use efficiency or SNUPE on regional level which should be matched best possible
withdrawals	nitrogen withdrawals on cell level
organicinputs	non-inroganic fertilizer inputs on cell level
threshold	threshold in Tg Nr until when the distribution counts as converged

Value

magpie object with fertilizer usage on cell level
