| Outline of Final Research Achievements |
The purpose was to clarify the relationship between the priming effect (PE) and the temperature sensitivity and clarify the influence of PE on the temperature coefficient (Q10) in soil. As a result, PE showed no clear temperature sensitivity and showed the highest PE value at 15 ℃, and both showed negative PE values at 25 ℃ and 35 ℃ with allophanic Andosols. Since there was no significant difference in Q10 between control and cellulose plot, we found that PE is not likely to affect Q10 at least in allophane Andosols. Furthermore, it was also revealed that PE under each temperature condition does not clearly correlate with microbial biomass of soil after incubation.
