Calculate the index for the microbial biological activity

Source: R/pmn.R

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).

calc_pmn(B_LU_BRP, B_SOILTYPE_AGR, A_N_PMN)

Arguments

B_LU_BRP

(numeric) The crop code from the BRP

B_SOILTYPE_AGR

(character) The agricultural type of soil

A_N_PMN

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

Value

the normalized potentially mineralizable Nitrogen pool (mg N / kg), a numeric value.

Examples

calc_pmn(B_LU_BRP = 256, B_SOILTYPE_AGR = 'dekzand', A_N_PMN = 125)
#> [1] 102.7778
calc_pmn(B_LU_BRP = c(256,1027), B_SOILTYPE_AGR = c('dekzand','rivierklei'), A_N_PMN = c(125,45))
#> [1] 102.77778  23.57143
