Description

fertilization_treatments.csv is a comma-separated text file containing the fertilization treatments of the Gigante experiment. Column definitions are:

  1. treatment is the fertilization treatment, where N = nitrogen, P = phosphorus and K = potassium.
  2. plot is the plot number associated with each treatment.

root_abundance_and_morphological_traits.csv is a comma-separated text file containing the root abundance and morphological trait dataset. Column definitions are:

  1. plot is treatment plot.
  2. core is core sample number.
  3. size_class is root diameter size class, where 0 = 0–1 mm, 1 = 1–2 mm and 2 = 0–2 mm.
  4. biomass is root biomass in g/m2
  5. length is root length in m/m2
  6. t_den is root tissue density in g/cm3
  7. srl is specific root length in cm/g
  8. avg_diam is average root diameter in mm.

root_nutrients.csv is a comma-separated text file containing the nutrient content of root tissue samples. Column definitions are:

  1. plot is treatment plot
  2. size_class is root diameter size class, where 0 = 0–1 mm, 1 = 1–2 mm and 2 = 0–2 mm.
  3. N is root tissue nitrogen concentration (%).
  4. C is root tissue carbon concentration (%).
  5. P is root tissue phosphorus concentration (ppm).
  6. K is root tissue potassium concentration (ppm).

mycorrhizal_colonization.csv is a comma-separated text file containing mycorrhizal colonization dataset. Column definitions are:

  1. plot is treatment plot.
  2. arb_per is colonization of arbuscules expressed as a percent of root length
  3. ves_per is colonization of vesicles expressed as a percent of root length
  4. hyp_per is colonization of hyphae expressed as a percent of root length
  5. tot_per is total colonization expressed as a percent of root length
  6. arb_len is colonization of arbuscules expressed as root length (cm).
  7. ves_len is colonization of vesicles expressed as root length (cm).
  8. hyp_len is colonization of hyphae expressed as root length (cm).
  9. tot_len is total colonization expressed as root length (cm).
