  B_LU,
  A_N_RT,
  A_C_OF,
  A_CLAY_MI,
  A_SAND_MI,
  A_CACO3_IF,
  B_PREC_SUM = NA_real_,
  B_PREC_WIN = NA_real_,
  B_PET_SUM = NA_real_,
  B_PET_WIN = NA_real_,
  B_TEMP_SUM = NA_real_,
  B_TEMP_WIN = NA_real_
)

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 (%)

B_PREC_SUM

(numeric) Total potential precipitation in summer (mm)

B_PREC_WIN

(numeric) Total potential precipitation in winter (mm)

B_PET_SUM

(numeric) Total potential evapotranspiration in summer (mm)

B_PET_WIN

(numeric) Total potential evapotranspiration in winter (mm)

B_TEMP_SUM

(numeric) Mean winter temperature (degrees Celcius)

B_TEMP_WIN

(numeric) Mean winter temperature (degrees Celcius)

Value

The risk of nitrogen leaching. A numeric value, converted to a OSI score.
