    carbon (MBC) and nitrogen (MBN), as well as dehydrogenase (DHA) and β-glucosidase (β-Glu) activities were analyzed in both experiments. Results showed that glyphosate acted as a source of organic carbon in both experiments, however, stimulation effects on MBC, MBN, DHA and β-Glu were more evident and lasted longer for the incubated samples. In this experiment, the maximum values for MBC, MBN and DHA were registered between 18 and 37 days after application, while higher β-Glu values under reduced tillage were still registered after 101 days. Those effects were less noticeable in the on-field experiment. Under our experimental conditions (Entisol, Mediterranean condition, rainfed agriculture, wheat-sunflower-fodder pea rotation), an interval of at least 30 days between glyphosate application and soil sampling should be adopted as a standard to avoid data misinterpretation.
