| Decay rate and nutrient dynamics during decomposition of oak (Quercus acutissima) branches were investigated for 33-months in Kongju, Korea. After 33-months, remaining weight of B©û, B©ü and B©ý was 44.5%, 58.5% and 55.37%, respectively. Decomposition constant (k) for B©û, B©ü and B©ý was 0.294/yr, 0.195/yr, 0.215/yr, respectively. N concentration in decomposing oak branches increased in all diameter classes. After 33-months, remaining N in B©û, B©ü and B©ý was 101.2%, 91.9%, 104.4%, respectively. P concentration in decomposing oak branches increased in B©û and B©ü, and there was no immobilization period. After 33-months, remaining P in B©û, B©ü and B©ý was 57.2%, 74.4%, 53.9%, respectively. K concentration in decomposing oak branches decreased significantly. Remaining K in B©û, B©ü and B©ý was 7.7%, 17.1% and 17.2%, respectively, which was significantly lower than other nutrients. Ca concentration in decomposing oak branches increased in B©ü and B©ý. After 33-months, remaining Ca in B©û, B©ü and B©ý was 58.5%, 47.8% and 75.2%, respectively. Initial concentration of Mg in oak branch was higher in smaller diameter class. After 33-months, remaining Mg in B©û, B©ü and B©ý was 44.3%, 57.9% and 47.7%, respectively. |
