Collembola Field Study
Collembolans are said to have direct and indirect effect on organic matter breakdown and soil nutrient recycling, with their faecal pellets creating favorable habitat for microorganism development.
- The study design is according to ISO 23611-2 (2007) and de Jong F.M.W. et al. (2010).
- The basic experimental design comprises three treatment groups; a negative control (water treated control), a positive control (reference substance) and the test item.
- The test is designed as a randomized complete block with at least four replicates for each treatment (10 m * 10 m per plot), with at least 3 m bdistance between each plot and 10 m distance to adjacent fields.
Collembolans are sampled from the soil by combining two different methods, to cover the ecological groups:
- Soil core samplers
Collembolans are extracted from the soil cores using the Mac Fayden heat extraction method.
