Soil Physical and Chemical Data from Manganiferous Soils

Description

Soil Physical and Chemical Data from Manganiferous Soils (Bourgault and Rabenhorst, 2011)

Format

A data frame with 30 observations on the following 13 variables.

id: pedon name
name: horizon designation
top: horizon top boundary in cm
bottom: horizon bottom boundary in cm
color: moist soil color in Munsell notation
texture: USDA soil texture class
sand: sand content by weight percentage
silt: silt content by weight percentage
clay: clay content by weight percentage
Fe: DCB-extracted Fe in g/kg (see citation)
Mn: DCB-extracted Mn in g/kg (see citation)
C: total organic carbon as g/kg
pH: measured in 1:1 H20 slurry
Db: bulk density (g/cc), clod method

Details

Selected soil physical and chemical data from (Bourgault and Rabenhorst, 2011).

Examples

# setup environment
  library(aqp)
  data(sp6)

  # init SPC
  depths(sp6) <- id ~ top + bottom
  # convert non-standard Munsell colors
  sp6$soil_color <- getClosestMunsellChip(sp6$color)

  # profile sketches
  par(mar=c(0,0,3,0))
  plot(sp6, color='soil_color')
  plot(sp6, color='Mn')
  plot(sp6, color='Fe')
  plot(sp6, color='pH')
