- Title
- Comparision of native litter species occurring at the Andrews Experimental Forest to LIDET standard species, 1993-2003
- 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.
