Application of ~(14)C-labeling technique in the study on the turnover of soil organic matter.

LI Ling 1,2,XIAO Heai1,HUANG Daoyou1,WU Jinshui1 ( ( 1Key Laboratory of Subtropical Agro ecology,Institute of Subtropical Agr iculture,Chinese Academy of Sciences,Changsha 410125, China; 2Graduate School of Chinese Academy of Sciences,Beijing 100039, China).  
Using carbon isotope (e.g.radioactive 14C) labeled organic materials i s relativ ely reliable to reflect the dynamics in their decomposition and transformation p rocesses in soil,and an essential method to investigate the turnover of soil or ganic matter.This paper reviewed the advances in the use of 14C-label ing techni que for determining the dynamics in the formation and decomposition of humus sub stances,the decomposition and transformations of organic materials and effects of their addition on the decomposition of native soil organic matter,the turnov er of microbial biomass C,and the emission of carbon gases.
