Abstract

Weight loss and nutrients dynamics during decomposition of oak roots (diameter classes:R1<0.2cm, 0.5cm<R2<1cm, 1cm<R3<2cm, 2cm<R4<4cm) (Quercus acutissima) were studied for 33-months in Kongju, Korea. After 33-months, decomposition rate of R1, R2, R3 and R4 was 49.6%, 47.5%, 66.4% and 66.1%, respectively. The decomposition constant(k) for R1, R2, R3, and R4 was 0.249/yr, 0.234/yr, 0.397/yr and 0.393/yr, respectively. Larger diameter class of the root lost more weight than smaller diameter class. N concentration in decomposing oak roots increased in all diameter classes. After 33-months, remaining N in R1, R2, R3 and R4 was 66.5%, 86.7%, 84.4% and 44.4%, respectively. P concentration in decomposing oak roots decreased in early part of decomposition and then increased in later stage of decomposition. After 33-months, remaining P in R1, R2, R3 and R4 was 64.7%, 62.4%, 93.1% and 30.7%, respectively. K concentration in decomposing oak roots decreased rapidly in early stage of decomposition. Remaining K in R1, R2, R3 and R4 was 11.6%, 10.6%, 5.9% and 7.7%, respectively. Ca concentration in decomposing oak roots showed different among diameter classes. After 33-months, remaining Ca in R1, R2, R3 and R4 was 66.2%, 51.0%, 39.1% and 48.3%, respectively. Initial concentration of Mg in oak root was higher in smaller diameter class. After 33-months, remaining Mg in R1, R2, R3 and R4 was 15.3%, 29.9%, 24.6% and 69.4%, respectively.
