<h2>File List</h2><div> <p><a href="supplemental_litter_leaching_20120822.csv">supplemental_litter_leaching_20120822.csv</a> (md5: a5b18924aff40de97816e3a41342150a) </p> </div><h2>Description</h2><div> <p>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.</p> <p>Columns are as follows:</p> <p>1. Species. Species are referenced by species code. See <a href="appendix-A.htm">Appendix A</a> for species names.</p> <p>2. Total Al concentration in the initial litter expressed as mg Al/g litter.</p> <p>3. Total C concentration in the initial litter expressed as mg C/g litter.</p> <p>4. Total Ca concentration in the initial litter expressed as mg Ca/g litter.</p> <p>5. Total K concentration in the initial litter expressed as mg K/g litter.</p> <p>6. Total Mg concentration in the initial litter expressed as mg Mg/g litter.</p> <p>7. Total N concentration in the initial litter expressed as mg N/g litter.</p> <p>8. Total Na concentration in the initial litter expressed as mg Na/g litter.</p> <p>9. Total P concentration in the initial litter expressed as mg P/g litter.</p> <p>10. Percent lignin in initial litter.</p> <p>11. Water extractable Al expressed as extracted mg Al/g litter.</p> <p>12. Dissolved organic carbon expressed as extracted mg C/g litter.</p> <p>13. Water extractable Ca expressed as extracted mg Ca/g litter.</p> <p>14. Water extractable K expressed as extracted mg K/g litter.</p> <p>15. Water extractable Mg expressed as extracted mg Mg/g litter.</p> <p>16. Water extractable Na expressed as extracted mg Na/g litter.</p> <p>17. Water extractable total N (inorganic + organic N) expressed as extracted mg N/g litter.</p> <p>18. Water extractable N-NH4 expressed as extracted mg N/g litter.</p> <p>19. Water extractable N-NO3 expressed as extracted mg N/g litter.</p> <p>20. Water extractable molybdate reactive phosphorus (commonly referred to as orthophosphate) expressed as extracted mg P/g litter.</p> <p>21. Water extractable total P (inorganic + organic) expressed as extracted mg P/g litter.</p> <p>22. Leachate pH.</p> <p>Missing data</p> <p>NA indicates ‘not available’.</p> </div>
