Description of study
What?
A set of nested catchments, south-east of Toowoomba on the Darling Downs, Queensland, was monitored over the summer of 2001–02. The hill catchment contained mountain coolabah open woodland and the 2 monitored contour bays (steep and low slope bays) were cultivated and planted to sorghum, as were the adjacent contour bays. The soil was a self mulching Black Vertosol.
How?
Soil was sampled from the steep and low slope bays using a 50-mm-diameter corer, with samples taken at 6–8 randomly selected locations for each bay and bulked for each bay. Sampling depth increments were 0–0.05, 0.05–0.10, 0.10–0.20, and 0.10–0.30 m. Soil sampling was conducted 2, 16, 30, 57, 90, and 128 days after herbicide application on 19 September. Soil cores were frozen directly after collection. All soil samples were delivered to an analytical laboratory within 5 days of collection and were extracted within 1 week of arrival at the laboratory. Average herbicide concentrations in soil were calculated for the 2 contour bays and these values were used in subsequent analyses.
