Changes in soil microbial community and activity caused by application of dimethachlor and linuron

Abstract Soil microorganisms and their activities are essential for maintaining soil health and fertility. Microorganisms can be negatively affected by application of herbicides. Although effects of herbicides on microorganisms are widely studied, there is a lack of information for chloroacetamide h...
