Supplement 1. Initial litter quality and water-soluble element data by species

File List supplemental_litter_leaching_20120822.csv (md5: a5b18924aff40de97816e3a41342150a) Description The file contains initial litter quality and water soluble element data listed by species. Initial litter quality data was determined by grinding and homogenizing 10 g of litter (petioles removed) per species. Water soluble element and pH data show the average of three water extracts per species, with the exception of inorganic N that only had two replicates per species. Water soluble element and pH data are from 4 h extracts. All data expressed on a litter mass basis use oven-dried (60°C) mass. Columns are as follows: 1. Species. Species are referenced by species code. See Appendix A for species names. 2. Total Al concentration in the initial litter expressed as mg Al/g litter. 3. Total C concentration in the initial litter expressed as mg C/g litter. 4. Total Ca concentration in the initial litter expressed as mg Ca/g litter. 5. Total K concentration in the initial litter expressed as mg K/g litter. 6. Total Mg concentration in the initial litter expressed as mg Mg/g litter. 7. Total N concentration in the initial litter expressed as mg N/g litter. 8. Total Na concentration in the initial litter expressed as mg Na/g litter. 9. Total P concentration in the initial litter expressed as mg P/g litter. 10. Percent lignin in initial litter. 11. Water extractable Al expressed as extracted mg Al/g litter. 12. Dissolved organic carbon expressed as extracted mg C/g litter. 13. Water extractable Ca expressed as extracted mg Ca/g litter. 14. Water extractable K expressed as extracted mg K/g litter. 15. Water extractable Mg expressed as extracted mg Mg/g litter. 16. Water extractable Na expressed as extracted mg Na/g litter. 17. Water extractable total N (inorganic + organic N) expressed as extracted mg N/g litter. 18. Water extractable N-NH4 expressed as extracted mg N/g litter. 19. Water extractable N-NO3 expressed as extracted mg N/g litter. 20. Water extractable molybdate reactive phosphorus (commonly referred to as orthophosphate) expressed as extracted mg P/g litter. 21. Water extractable total P (inorganic + organic) expressed as extracted mg P/g litter. 22. Leachate pH. Missing data NA indicates ‘not available’.
