calc_bcs {OBIC}

Calculate the BodemConditieScore

Description

This function calculates the BodemConditieScore given input from manual observations made in the field. The individual parameters are scored in three classes: poor (0), neutral (1) or good (2) More information on this test can be found here

Usage

calc_bcs(
  B_LU_BRP,
  B_SOILTYPE_AGR,

  A_EW_BCS = NA,
  A_SC_BCS = NA,
  A_GS_BCS = NA,
  A_P_BCS = NA,
  A_C_BCS = NA,
  A_RT_BCS = NA,
  A_RD_BCS = NA,
  A_SS_BCS = NA,
  A_CC_BCS = NA,
  type = "score"
)
