Calculate risk of pesticide leaching

Source: R/pesticides.R

This function calculates the risk of pesticide leaching from a soil. The risk is calculated by comparing the current leached fraction with a worst case scenario

calc_pesticide_leaching(
  B_SOILTYPE_AGR,
  A_SOM_LOI,
  A_CLAY_MI,
  A_SAND_MI,
  A_SILT_MI,
  D_PSP,
  M_PESTICIDES_DST,
  M_MECHWEEDS
)

Arguments

B_SOILTYPE_AGR

(character) The agricultural type of soil

A_SOM_LOI

(numeric) The percentage organic matter in the soil (%)

A_CLAY_MI

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

A_SAND_MI

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

A_SILT_MI

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

D_PSP

(numeric) The precipitation surplus per crop calculated by calc_psp

M_PESTICIDES_DST

(boolean) measure. Use of DST for pesticides (option: TRUE or FALSE)

M_MECHWEEDS

(boolean) measure. Use of mechanical weed protection (option: TRUE or FALSE)

Value

The risk of pesticide leaching from soils. A numeric value.

Examples
