Glyphosate [N-(phosphonomethyl)-glycine] is a broad-spectrum, non-selective, post-emergence herbicide that is widely used in agricultural. The object of this work was to study the dynamic of glyphosate mineralization in different agricultural soils characteristic to the west part of Romania: Black Chernozem, Typical Gleysol, Phaeozom and Slight Vertisol with moderate carbonation. To follow the quantity of degraded product in the presence of micro-organisms, in microbiology its use radio-perspiration-metre of studied mineralization molecule, determining the soil perspiration potential in the presence of microorganisms.
The quantity of free CO2 as result of glyphosate biodegradation under the microorganisms action is bigger in all four analysed soils comparatively with blind sample (uncured soil), which demonstrate the microbiological biodegradation capacity of the herbicide.
