Nicosulfuron is one of the most applicable sulfonylurea herbicides for control of annual and
perennial weeds in maize. Its residues can persist in soil at phytotoxic concentrations and affect
sensitive succeeding crops more than one season after treatment. Therefore, monitoring the
trace levels of this herbicide in soil is a challenging task and demands highly efficient, selective,
and sensitive analytical technique. This study was conducted for the purpose of investigating
nicosulfuron residues presence in soil. Soil samples were collected before crop seeding, from
two soil layers, surface (0-30 cm) and sub-surface (30-60 cm). Nicosulfuron determination and
quantification were performed by HPLC with diode-array detection, using isocratic elution of
mobile phase. Nicosulfuron was extracted from the soil sample with mixture of phosphate
buffer (pH 7.4)/methanal (80/20, v/v) solution with clean-up on C18 extraction cartridge. The
linearity of detector response showed that the c...alibration curves were linear with correlation
coefficient (R’) of 0.999. Relative standard deviations (RSD) of the retention times and of the
peak areas were 0.79 and 1.06%, respectively and fulfilled the criteria of chromatographic
measurements. The accuracy of the defined method was confirmed by the good results of
recovery assay, while achieved limit of detection (LOD) and limit of quantification (LOO) for
nicosulturon in soil were in accordance with SANCO/825/00 (SANCO, 2010). The proposed
analytical procedure was applied for monitoring of nicosulfuron herbicide in soil. Average values
of nicosulfuron residues in soil samples from surface and sub-surface horizon were 0.05 mg/kg.
