PEcAn.data.land 1.9.0.9000

Added

Fixed

  • soil2netcdf() no longer drops depth information for soils with only one layer. (#3785)

  • soil_params() where bulk density is not specified by the user now look up soil_bulk_density from the soil type (as always intended) instead of always reporting 1350 kg/m3 because of a flow control typo. (#3776)

  • Datasets

    • landiq_crop_mapping_codes dataset mapping LandIQ crop classification codes to human-readable crop names.
    • bism_kc_by_crop dataset containing BISm crop coefficient schedules and stage timing references for use in ET estimation, including columns that map to LandIQ class and subclass.
    • ca_n_application_rate dataset with recommended N application rates (g N/m2) for 33 California crops from CDFA-FREP and UC ANR sources.
    • ca_compost_amendment dataset with C:N ratios, carbon, nitrogen, and PAN (g/m2) for 32 organic amendment materials.

  • Functions

    • look_up_ca_n_rate() for looking up crop-specific N application rates by name (exact match first, partial match suggestions on miss).
    • look_up_ca_compost_amendment() for looking up organic amendment properties by material name.
    • to_co2e() for converting SOC change, CH4, and N2O to CO2-equivalent emissions using IPCC Global Warming Potential values.

Changed

  • Package traits, used by match_pft() and match_species_id() only when no database connection is provided, is now suggested rather than required.
  • Packages doSNOW, dplR, httr, MCMCpack, mvtnorm, neonUtilities, neonstore, PEcAn.benchmark, PEcAn.visualization, rjags, sirt, and sp are now suggested rather than required. They are only needed for specific optional functionality. (#3599)

PEcAn.data.land 1.9.0

Added

  • New function soilgrids_ic_process(), with helpers preprocess_soilgrids_data() and generate_soilgrids_ensemble(), generates soil carbon initial conditions from SoilGrids 250m data (#3508).
  • New function clip_and_save_raster_file() subsets rasters to match a polygon of interest (#3537).
  • New function look_up_fertilizer_component() contains typical carbon and nitrogen composition of common fertilizer types (#3559).
  • New PEcAn standard for events.json files. These contain information about management events (planting, harvest, irrigation, etc). The standard is defined in inst/events_schema_v0.1.0.json and event files can be validated against the schema with new function validate_events() (#3623, #3521).

Changed

  • Read.IC.info.BADM now processes both single-site and multi-site settings, and uses more carbon pools (ROOT_BIOMASS, AG_BIOMASS, SOIL_STOCK, LIT_BIOMASS) if they are present (#3536).
  • Package swfscMisc is no longer imported; it was formerly used in extract_NEON_veg() to compute distances and has been replaced by use of terra::distance() (#3552).
  • extract_soil_gssurgo() now supports spatial grid sampling using new arguments grid_size and grid_spacing. Previously available argument radius has been removed (#3534).
  • extract_soil_gssurgo() now reports an estimate of soil organic carbon stocks (#3534).

Removed

Fixed

PEcAn.data.land 1.8.1

  • Dependency datapack is now optional. It is only used by dataone_download() (#3373).
  • soilgrids_soilC_extract() no longer returns an empty dataframe when none of the queried locations are missing data. (#3409)
  • Functions that name output folders from settings$siteID no longer assume IDs are numeric

PEcAn.data.land 1.8.0

Added

  • New function soilgrids_soilC_extract retrieves soil C estimates with uncertainty from the ISRIC SoilGrids 250m data. (#3040, @Qianyuxuan)

Fixed

  • gSSURGO.Query() now always returns all the columns requested, even ones that are all NA. It also now always requires mukeys to be specified.
  • Updated gSSURGO.Query() and extract_soil_gssurgo() to work again after formatting changes in the underlying gSSURGO API

Removed

  • find.land() has been removed. It is not used anywhere we know if, has apparently not been working for some time, and relied on the maptools package which is scheduled for retirement.
  • Removed dependency on PEcAn.data.atmosphere, notably by retrieving site latitude and longitude directly from PEcAn.DB::query.site instead of custom lookups (#3300, Abhinav Pandey).
