Estimate default values for management

Source: R/management_defaults.R

This function adds default management input variables given soil type and land use

add_management(

  M_EARLYCROP = NA,
  M_COMPOST = NA_real_,
  M_SLEEPHOSE = NA,
  M_DRAIN = NA,
  M_DITCH = NA,
  M_UNDERSEED = NA,
  M_LIME = NA,
  M_NONINVTILL = NA,
  M_SSPM = NA,
  M_SOLIDMANURE = NA,

  M_PESTICIDES_DST = NA
)

Arguments

ID

(character) A field id

B_LU_BRP

(numeric) The crop code from the BRP

B_SOILTYPE_AGR

(character) The agricultural type of soil

M_GREEN

(boolean) A soil measure. Are catch crops sown after main crop (optional, option: yes or no)

M_NONBARE

(boolean) A soil measure. Is parcel for 80 percent of the year cultivated and 'green' (optional, option: yes or no)

M_EARLYCROP

(boolean) A soil measure. Use of early crop varieties to avoid late harvesting (optional, option: yes or no)

M_COMPOST

(numeric) The frequency that compost is applied (optional, every x years)

M_SLEEPHOSE

(boolean) A soil measure. Is sleephose used for slurry application (optional, option: yes or no)

M_DRAIN

(boolean) A soil measure. Are under water drains installed in peaty soils (optional, option: yes or no)

M_DITCH

(boolean) A soil measure. Are ditched maintained carefully and slib applied on the land (optional, option: yes or no)

M_UNDERSEED

(boolean) A soil measure. Is grass used as second crop in between maize rows (optional, option: yes or no)

M_LIME

(boolean) measure. Has field been limed in last three years (option: yes or no)

M_NONINVTILL

(boolean) measure. Non inversion tillage (option: yes or no)

M_SSPM

(boolean) measure. Soil Structure Protection Measures, such as fixed driving lines, low pressure tires, and light weighted machinery (option: yes or no)

M_SOLIDMANURE

(boolean) measure. Use of solid manure (option: yes or no)

M_STRAWRESIDUE

(boolean) measure. Application of straw residues (option: yes or no)

M_MECHWEEDS

(boolean) measure. Use of mechanical weed protection (option: yes or no)

M_PESTICIDES_DST

(boolean) measure. Use of DST for pesticides (option: yes or no)

Value

A data.table with all default estimates for the management measures that are used for the Label Sustainable Soil Management. For each B_LU_BRP 15 management measures are given, all as boolean variables except for M_COMPOST being a numeric value.
