Abstract: This study has proposed the identification of glyphosate degradation capacity in trees plantation in the scientific didactic resort of Banat’s University of Agricultural Sciences and Veterinary Medicine Timisoara, Romania compared with experiments realized on the same soil in laboratory conditions. Laboratory analysis of glyphosate residues in soil were made using TRIATHLER Scientilator liquid. Radioactivity brought by the C14 glyphosate standard to fosfonometil group was 37kBq for each soil. Evolution of glyphosate mineralization in soil was highlighted by capturing 14CO2 evolved following the action of soil microorganisms on herbicide, in 0.2 M NaOH solution at various time intervals. Results indicate that the percentage of CO2 accumulated after glyphosate biodegradation under the action of microorganisms is higher in the laboratory experiment compared with the results from experimental field. C02 fraction accumulated after 50 days ,is 73.42% in the laboratory experiment versus 28.02% for samples exposed in the experimental field.
