Effect of different organic matters on the availability of added Cu in two soils

LU Xiao-hui,LI Cheng-hou,TU Cheng-long(Department of Environment Science,College of Biological and Environment Science,Guizhou University,Guizhou Guiyang 550025,China)  
The yellow soil and brunisolic soil supplemented with Cu (200mg·kg~(-1)) were cultivated with four organic matters for six months in the laboratory. The results are discussed by the analysis of variance and the multiple comparison.Peat and weathering coal both significantly reduce the content of available copper,and the effect of peat is more obvious.The effects of corn straw and pig manure on the available copper are complicated.The proper dose is lower in yellow soil than in brunisolic soil,because of the different soil properties.In yellow soil,the influence is mainly in the 90 days;but in brunisolic soil,it is in the 45 days.
