Calculate the soil nitrogen supplying capacity in Germany

This function calculates the nitrogen producing capacity of the soil, and applies correction factors used affecting N availability.

Usage

osi_c_nitrogen_de(
  B_LU = NA_character_,
  A_CLAY_MI = NA_real_,
  A_SAND_MI = NA_real_,
  A_SOM_LOI = NA_real_,
  A_C_OF = NA_real_,
  A_N_RT = NA_real_
)

Arguments

B_LU

(character) The crop code

A_CLAY_MI

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

A_SAND_MI

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

A_SOM_LOI

(numeric) The percentage organic matter in the soil

A_C_OF

(numeric) The organic carbon content in the soil (g C / kg)

A_N_RT

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

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_de(B_LU= 2515, A_CLAY_MI = 25, A_SAND_MI = 7.5, A_SOM_LOI = 4.5, A_N_RT = 2500)
