Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 216 (Soil Microorganisms: Nitrogen Transformation Test)
- Deviations:
- yes
- Remarks:
- The soil water content maintained at the starting value within a range of ± 5 % for all sampling dates and rates, except day 28, when the deviation was 8% for the control and 6% for test rate 2.
- Principles of method if other than guideline:
- The soil water content maintained at the starting value within a range of ± 5 % for all sampling dates and rates, except day 28, when the deviation was 8% for the control and 6% for test rate 2. The deviation during incubation time was justifiable and occurred only in control and test rate 2 at day 28. Most time the water content was in the desired range.
- GLP compliance:
- yes (incl. QA statement)
