摘要：
The relationship between a microbial biomass respiration response to added C and N (NIR) and N mineralized in buried-bags in the field was examined. Significant negative correlations were found between organic horizon NIR values and the amount of mineralized N measured at various times, however no significant correlations were found in the mineral horizon. These results suggest that NIR has potential for use as a physiological indicator of forest floor N availability.
