# LTER Intersite Fine Litter Decomposition Experiment (LIDET), 1990 to 2002

## Dataset

- **Database Code:** TD023

- **Title:** LTER Intersite Fine Litter Decomposition Experiment (LIDET), 1990 to 2002

- **Abstract:**

The primary objective of this study is to examine the control that substrate quality and climate have on patterns of long-term decomposition and nitrogen accumulation in above- and below-ground fine litter. Of particular interest will be to examine the degree these two factors control the formation of stable organic matter and nitrogen after extensive decay.


- **Keywords:** decay rates; decomposition; litterfall; inorganic nutrients; wood; carbon; nitrogen; phosphorus; organic matter; roots; fine roots; leaf litter; inorganic nutrients; organic matter

- **Temporal coverage:** 1990-01-31 to 2007-06-12

- **Principal Investigator:** Mark E. Harmon
