Abstract

The dissolved organic carbon (DOC)of forest soil in Fujian Province was tested with TOC-5000A Organic Carbon Instrument .The relationship between soil DOC and soil factors were analyzed .The findings show that there is a very significant positive correlation between the concentration of DOC and the concentrations of organic carbon , total nitrogen , total phosphourus , available nitrogen , available phosphorus and available potassium .So DOC can be used as an index of soil fertility .A very significant positive or a positive correlation is found between the DOC concentration of soil and the concentration of organic-iron , organic-aluminum and active aluminum , which means that soil DOC is one of the important factors controlling the migration of aluminum and iron in soil. A very significant negative correlation is found between the concentrations of DOC and soil pH value .In the acid forest soil of south China , the absorption , maintenance and release of aluminum and iron are strongly controlled by DOC .There is no significant correlation between soil DOC and exchangeable aluminum .
