Abstract: | The decomposition of atrazine, linuron and picloram when incubated with two soils at four levels of application was measured for periods of 3 or 4 months. The applicability of zero-order, half-order, first-order and Michaelis-Menten kinetics was considered. None of the equations described the breakdown rates adequately in spite of the apparent theoretical advantage for using an expression of the Michaelis-Menten type. In each case the rate of decomposition increased as the initial herbicide concentration decreased. |
