Calculate the soil nitrogen supplying capacity in the Netherlands

This function calculates the NLV (nitrogen producing capacity) for the soil

Usage

osi_c_nitrogen_nl(B_LU, B_SOILTYPE_AGR, A_SOM_LOI, A_N_RT, unitcheck = TRUE)

Arguments

B_LU

(numeric) The crop code from the BRP

B_SOILTYPE_AGR

(character) The agricultural type of soil

A_SOM_LOI

(numeric) The percentage organic matter in the soil

A_N_RT

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

unitcheck

(character) Option to switch off unit checks (TRUE or FALSE)

Value

The capacity of the soil to supply nitrogen (kg N / ha / yr). A numeric value, converted to a OSI score.

Examples

osi_c_nitrogen_nl(B_LU = '256', B_SOILTYPE_AGR = 'dekzand',
A_SOM_LOI = 4.5,A_N_RT = 2500)
#> [1] 1
osi_c_nitrogen_nl(1019,'dekzand',5.5,2315)
#> [1] 1
