Calculate the soil nitrogen supplying capacity in Belgium

This function calculates the NSC (nitrogen supply capacity) for the soil

Usage

osi_c_nitrogen_be(B_LU, A_N_RT, A_C_OF, A_CLAY_MI, A_SAND_MI, A_CACO3_IF)

Arguments

B_LU

(character) The crop code

A_N_RT

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

A_C_OF

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

A_CLAY_MI

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

A_SAND_MI

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

A_CACO3_IF

(numeric) The percentage of carbonated lime (%)

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_be(B_LU = '772',A_N_RT = 1200, A_C_OF = 25, 
A_CLAY_MI = 3.5, A_SAND_MI = 15,A_CACO3_IF = 0.8)
