1. An investigation was performed to reveal the relation of the production and decomposition of the pine and oak litters in the Kwagnung plantation stand.
2. The total annual litter production was 2700 pounds in the pine and 3700 pounds in the oak stands on an acre basis.
3. The decay constant, k, or litters was as follows; k=0.13 for pine, k=0.28 for oak stand.
4. The curve for the accumulation of organic carbon derived from pine and oak litters is rising up to steady state with a zigzag path in Kwangnung plantation stand.
5. The time required for the decomposition of half of the accumulated organic matter of pine and oak stand are 5.3 and 2.5 years and for 99% of elimination 38.4 and 17.9 years.
6. The amount of the mineral nutrients returned annually to the soil is higher in the oak forest than in the pine forest.
