Abstract:
A modified multipoint method for enumeration of bacteria capable of various biochemical degradation reactions in soil is described.After continuous two\|crop winter wheat and summer corn rotation with no\|tillage for many years,the counts of hydrolysis of starch,xylan,pectin,protein,cellulose,chitin,lecithin and lipids bacteria were all increased significantly in no\|tillage 0\|10 cm soil depth compared to conventional tillage and direct drilling.
