This function calculates the NLV (nitrogen producing capacity) for the soil
Usage
bln_c_nitrogen(B_LU_BRP, B_SOILTYPE_AGR, A_SOM_LOI, A_N_RT, A_CN_FR = NA_real_)
Arguments
- B_LU_BRP
(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
- A_CN_FR
(numeric) The carbon to nitrogen ratio (-)
Value
The capacity of the soil to supply nitrogen (kg N / ha / yr). A numeric value, converted to a OSI score.
Examples
bln_c_nitrogen(B_LU_BRP = 256, B_SOILTYPE_AGR = 'dekzand',A_SOM_LOI = 4.5,A_N_RT = 2500)
#> [1] 1
bln_c_nitrogen(1019,'dekzand',5.5,2315)
