Study design
- Details on sampling:
- For the untreated samples, soil cores were taken from 5 randomly distributed points within the untreated plot. The sampling points within the treated plot were within a 12.5 cm radius of the sampling point for each core taken.
Sample 1 (S1): Diluent sample taken immediately prior to T1 application
Sample 2 (S2): Spray deposition samples taken during T1 application
Sample 3 (S3): Soil cores taken 1 - 4 hours after T1 application
Results and discussion
- Details on results:
- The corrected results compare to the actual rates of recovery from each sample with the anticipated level, based on the surface area of each core. The results were corrected to take account of the procedural recovery rate and the diameters of the cutting edge of the soil core sleeves (21.0 mm and 42.5 mm, respectively). The results are presented in groups of 5 cores and the sub-plot means for each core are provided.

Applicant's summary and conclusion
- Conclusions:
- The results show that the 44 mm diameter cores gave a more accurate measurement of the true dose of pesticide applied to the soil than the 22.5 mm diameter cores. The most probable explanation is that there was a disproportionate disruption of the soil surface as the probe entered the soil, resulting in a smaller area of soil surface entering the tube than would be predicted from the real diameter of the tube.
