Interactive Leaf Decomposition Activity

This model of litter decomposition allows the selection of the litter type and the ecosystem in which it decomposes. The litter types differ in their chemical composition and the ecosystems differ in climate. For these reasons, decomposition will vary between litter types in the same ecosystem, or for the same litter type in different ecosystems. You can use it to simulate the decomposition of the litters that you select in the ecosystems that you choose. What happens to decomposition rates when you move a plant litter from one type of ecosystem to another? How does the composition of different plant litters affect how fast they decompose?

The litter chemistry data used in I•MOLD were obtained from the NSF-sponsored Long-Term Inter-site Decomposition Experiment Team (LIDET) project through the Oregon State University.
