Calculate the index for the microbial biological activity across the EU

osi_b_pmn_eu.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).

Usage

osi_b_pmn_eu(B_LU, A_N_RT, A_CLAY_MI)

Arguments

B_LU

(numeric) The crop code

A_N_RT

(numeric) The total N content of the soil(mg N / kg soil)

A_CLAY_MI

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

Value

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

Examples

osi_b_pmn_eu(B_LU = 256, A_CLAY_MI = 4.5, A_N_RT = 1250)
#> [1] 0.9999881
osi_b_pmn_eu(c(256,1027),c(4,48), c(3125,1450))
#> [1] 0.03568355 0.04499516
