The aim of this study was to apply the single first-order kinetic model (SFO) to the
investigation of linuron degradation (pure and in the mixture with other pesticides –
thiametoxam and mancozeb) in light and medium soil. Coefficients of the exponential model
were determined – after logarithmic transformation – from the least squares linear regression.
The single first-order reaction kinetic model turned out to be applicable to the degradation of
linuron in soil (determination coefficient R2 ≥ 92.7%). In light soil, the rate of degradation was
higher comparing to medium soil. The T50 values (half-life time) amounted to 36.1–49.2 days for
the herbicide alone and ranged from 71.5 to 73.5 days for linuron in the mixture. Regardless of
the type of soil, linuron in the mixture degraded much slower than the pure herbicide.
