Variables

DATASET_CODE

BASIN

Label:
Definition: The lake basin where the soil sample was collected from (Bonney or Fryxell).
Type: Code list
Codes:
- Bonney = Lake Bonney Basin
- Fryxell = Lake Fryxell Basin
Missing values: None specified

SAMPLE_ID

Label:
Definition: The block and treatment combination of the sample. (C) carbon additions as mannitol (N) nitrogen additions as NH4NO3 (P) phosphorus additions as Na3PO4 (CN) carbon and nitrogen additions (CP) carbon and phosphorus additions, (W) water-only additions (U) un-amended plots. The numbers indicated the plot/block number
Type: Nominal
Missing values: None specified

BLOCK_ID

TREATMENT

Label:
Definition: The manipulation for a given plot from where the soil was collected.
Type: Code list
Codes:
