Effects of filter mud and vinasse from sugar factory on quantity of soil microorganism in sugarcane field.

The present study was conducted to investigate the effects of filter mud and vinasse on the quantity of soil microorganism in sugarcane field through mixed landfill using nylon mesh bag in soil.The results showed that the total bacterial quantity in soil reached the maximum in one month after treatment with filter mud and vinasse.After two months and three months,the total actinomycetes quantity in soil treated with filter mud and vinasse reached the maximum,respectively.After three months,the total filamentous fungi quantity in soil treated with filter mud and vinasse reached the maximum.The total quantities of bacteria,actinomycetes and filamentous fungi in treated soil was 4.6,617.9,279.8,times and 8.4,242.9,82.8 times significantly higher than that of base soil,respectively.These results indicated that filter mud and vinasse had significant effect on improving quantity of soil microorganism in sugarcane field.
