What's Changed

Added

  • Function ind_gw_target() to modify I_H_GWR (renamed to I_E_GWR) with a correction factor based on
    soiltype and groundwaterclass akin to the groundwaterrecharge score from BBWPC.

Changed

  • Argument useClassicOBI is added to obi_field(), obi_field_dt(), and obi_farm().
    This argument defaults to TRUE, when TRUE, only agronomic indicators are calculated
    and aggregated. When FALSE, water-related indicators (groundwater recharge,
    pesticide leaching, and nitrogen use efficiency in relation to groundwater
    and surface water) are included in the environmental score and subsequently in
    the total score.
  • When useClassicOBI = FALSE, indicators for water quality and quantity (
    I_E_GW_NLEA, I_E_SW_NLEA, I_E_PEST, and I_E_GWR) are included in the
    calculation of S_E_OBI_A.
  • B_DRAIN no longer has a default value and must be supplied when useClassicOBI = FALSE
  • M_GREEN is set to TRUE for potato and maize on sandy soils by add_management(). This
    means that M_GREEN is overwritten for such cultivations when using one of the wrapper
    functions.
  • renamed I_H_NGW to I_E_GW_NLEA
  • renamed I_H_NSW to I_E_SW_NLEA
  • renamed I_H_PEST to I_E_PEST
  • renamed I_H_GWR to I_E_GWR
  • renamed I_E_NGW to I_E_GW_NRET, I_E_NGW is still part of the obic_field() and
    obic_farm() outputs but its use is deprecated, switch over to I_E_GW_NRET
  • renamed I_E_NSW to I_E_SW_NRET, I_E_NSW is still part of the obic_field() and
    obic_farm() outputs but its use is deprecated, switch over to I_E_SW_NRET
  • calc_psp() no longer changes makkink factors for specific months in a rotation.
    Instead, makkink factors are adjusted within a single year. For example, if in 2015
    potato is grown followed by a green manure and grassland in 2016, the makkink factors
    in 2015 for months 1,2 3, 10, 11, and 12 are set to 0.6 (even tough the green manure
    partially grows in 2016). One can now indicate in which months a green manure is
    grown, default is from 10 up to and including 3. Lastly, the makkink factor for green
    manure is only set to 0.6, and only when this is higher than the non-green manure
    factor. The makkink factor for month 10 used to be 0.74
  • Introduced argument B_AREA_DROUGHT for obic_field() and as possible column in
    obic_field_dt() and obic_farm(). This argument is passed on to ind_gw_recharge()
    which is only called when useClassicOBI == FALSE. When B_AREA_DROUGHT is missing
    but required, it is assigned a value in by obic_field() based on B_SOILTYPE_AGR
    and B_AER_CBS whilst raising a warning.

Fixed

  • B_FERT_NORM_FR and B_DRAIN can now be supplied when using obic_field_dt() or
    obic_farm(). The value is set to 1 when not supplied.

OBIC 4.1.0 2025-08-04

Added

  • BRP crop codes for 2025: 7137, 7138, 7135, 7134
