Calculate the index for the microbial biological activity (wrapper function)

osi_b_pmn.Rd

This function assesses the microbial biological activity (of microbes and fungi) via the Potentially Mineralizable N pool, also called PMN (or SoilLife by Eurofins in the past) for all European countries (if available).

Usage

osi_b_pmn(
  B_LU,
  B_SOILTYPE_AGR,
  A_CLAY_MI = NA_real_,
  A_N_PMN = NA_real_,
  A_N_RT = NA_real_,
  B_COUNTRY
)

Arguments

B_LU

(numeric) The crop code

B_SOILTYPE_AGR

(character) The agricultural type of soil

A_CLAY_MI

(numeric) The clay content of the soil (%)

A_N_PMN

(numeric) The potentially mineralizable N pool (mg N / kg soil)

A_N_RT

(numeric) The organic nitrogen content of the soil in mg N / kg

B_COUNTRY

(character) The country code

Value

the normalized potentially mineralizable Nitrogen pool (mg N / kg), a numeric value, converted to an OSI score.

Examples

osi_b_pmn(B_LU = 256, B_SOILTYPE_AGR = 'dekzand', A_N_PMN = 125, B_COUNTRY = 'NL')
#> [1] 0.9999999
osi_b_pmn(B_LU = c(256,1027), B_SOILTYPE_AGR = c('dekzand','rivierklei'), 
A_N_PMN = c(125,45),B_COUNTRY = c('NL','NL'))
#> [1] 0.9999999 0.7174464
