A method for extraction of bentazone, dichlorprop and MCPA in three selected Norwegian soils of different texture is described. Initially three different extraction methods were tested on one soil type. All methods gave recoveries > 80 % for the pesticide mixture, but extraction with sodium hydroxide in combination with solid phase preconcentration was used for further recovery tests with soils of different properties spiked at four herbicide concentration levels (0.001-10 mg/g wet soil). The method was rapid, easy and required a minimum of organic solvents. The recoveries were in the range of 82-109, 80-123 and 45-91 % for the soils containing 1.4 (Hole), 2.5 (Kroer) and 37.8 % (Froland ) organic carbon, respectively. Limits of quantification using GC-MS were 0.0003 mg/g wet soil for bentazone and 0.0001 mg/g wet soil for both dichlorprop and MCPA

Sorption-desorption kinetic and isotherm studies were performed by batch equilibrium technique in three Norwegian soils. The soils were a fine sandy loam, loam and a soil of highly decomposed organic material. Two commercially formulations were used, Triagran-P and Tilt, containing either a mixture of bentazone, dichlorprop, MCPA or propiconazole alone. Sorption/desorption equilibrium occurred within 10 h for all pesticides. The Freundlich isotherms indicated non-linear sorption of bentazone, dichlorprop, MCPA and propiconazole. Low 1/n values of all pesticides in the forest soil compared to the two agricultural soils revealed that sorption was more dependent upon concentration in the forest soil with higher percent sorption at lower concentration in the equilibrium solution. For all pesticides the highest KF values were in the soil with highest organic content and lowest pH. For the fine sandy loam and loam, which are representative Norwegian agricultural soils, the results indicate that bentazone, dichlorprop and MCPA are mobile with KF values ranging from 0.13 to 2.15 mg1-1/n kg-1 L1/n. Propiconazole is much less mobile with KF values ranging from 28.6 to 34.8 mg1-1/n kg-1 L1/n in the agricultural soils.
