Soil Respiration Responds to Nutrient Addition
in Northern Hardwood Forests
Tim Fahey, Cornell University
Shoestring2014 6-respiration
Components of Soil Respiration
• Heterotrophic respiration by microbial decomposers
• Root-associated respiration (supplied by belowground C
allocation)
- respiration of fine roots
- respiration of mycorrhizal fungi
- respiration of other rhizosphere microbes
Seasonal Pattern of Soil Respiration in Hubbard Brook Sites
Pre-treatment Pattern of Soil Respiration
Both soil respiration and estimated belowground carbon
allocation declined significantly with increasing soil nutrient
availability across the MELNHE sites

Shoestring2014 6-respiration

  • 1. Soil Respiration Responds to Nutrient Addition in Northern Hardwood Forests Tim Fahey, Cornell University
  • 3. Components of Soil Respiration • Heterotrophic respiration by microbial decomposers • Root-associated respiration (supplied by belowground C allocation) - respiration of fine roots - respiration of mycorrhizal fungi - respiration of other rhizosphere microbes
  • 4. Seasonal Pattern of Soil Respiration in Hubbard Brook Sites
  • 5. Pre-treatment Pattern of Soil Respiration Both soil respiration and estimated belowground carbon allocation declined significantly with increasing soil nutrient availability across the MELNHE sites
  • 6. -3 0 3 6 9 400 500 600 700 800 Oe 0 2 4 6 8 BelowgroundCallocation(gCm -2 yr -1 ) 400 500 600 700 800 Oa net nitrification (ug g-1 ) 0.2 0.3 0.4 0.5 0.6 0.7 0.8 400 500 600 700 800 0-10 cm 2000 3000 4000 5000 6000 7000 Oe 400 800 1200 1600 2000 Oa exchangable Ca (ug g-1 ) 0 100 200 300 400 500 0-10 cm R2=0.96 R2=0.80 R2=0.90 R2=0.73 R2=0.94 Pre-treatment observations for a sub-set of the sites
  • 7. Hypotheses 1. Addition of a tree growth-limiting nutrient will reduce belowground carbon allocation resulting in lower root-associated respiration 1a. Colimitation would be indicated by strong response of soil respiration to addition of N + P 2. Reduction of soil respiration will be greatest in most infertile sites 3. Nitrogen addition might suppress activity of microbial decomposers thereby complicating interpretation of respiration response
  • 8. Response ratio of soil respiration to nutrient additions We express the treatment effect on soil respiration as the ratio: % response ratio= ((fertilized – control)/control) * 100 Thus a negative response ratio indicates a reduction of soil respiration in the treated plots
  • 10. N + P Plots
  • 11. Note: no clear evidence of a decline of heterotrophic respiration in response to nutrient addition (next talk)
  • 12. Conclusions • Response of soil respiration to nutrient addition varies linearly with pre-treatment site fertility • Belowground carbon allocation in infertile sites decreases significantly in response to nutrient additions (resulting in tree aboveground growth increase?) • Some indication of possible co-limitation by N and P on infertile sites
  • 13. Acknowledgements Kikang, Hongzhang, Melany, Ruth and a cast of thousands
  • 14. What limits microbial respiration? Oie CO2 incorportation into Oa Litter and root inputs
  • 15. Questions: • Do N or P limit microbial respiration in forest floor? • Is this limitation secondary to that of C? • Does forest age or site affect respiratory responses? 3 sites: • Jeffers Brook • HBEF • BEF
  • 16. Approach: • Lab incubations • Treatments: Control C (litter) nutrient (N or P) C + nutrient
  • 18. • N suppressed respiration • With added C, P increased respiration
  • 19. N effect microbial biomass accumulation: 256 (101) DON accumulation: 440 (969) Litter effect inorganic N reduced by 82 (23) ug N/g Where the added N (mg/g soil) went: Ni: 137 (27) DON: 115 (14) MBN: 797 (95) Ni: 56 (7) DON: 114 (25) MBN: 877 (77) Ni: 840 (87) DON: 554 (99) MBN: 1082 (93) control + litter +N
  • 20. cellulases Hypothesized C, N, P interactions: Low N Microbial biomass synthesis CO2 Respiration
  • 21. cellulases Hypothesized C, N, P interactions: High N Microbial biomass synthesis Respiration CO2
  • 22. Why would P limitation be induced by added C? Hypothesized C, N, P interactions: N may also limit enzyme production, C availability. We predict that adding N and P together should increase microbial respiration
