Fungal, bacterial and plant dsDNA contributions to soil total DNA extracted from silty soils under different farming practices: Relationships with chloroform-labile carbon

► A strong logarithmic relationship can be drawn between Chloroform Labile Carbon and soil dsDNA for tilled lands and grasslands. ► The contribution of fungal, bacterial and plant dsDNA to total dsDNA extracted from soil can be estimated by real time PCR using universal primers for each kingdom. ► Fungal dsDNA concentration is highly related to tillage.
