Study Notes
Hay Infusion Preparation
- Hay infusion is prepared by mixing a handful of hay, cut into smaller pieces, with a handful of dried leaves in a container.
- 1 L of tap water (not distilled water) is added to the mixture.
- The mixture is then boiled until the water turns brownish-green, similar to tea.
- After boiling, the solution is allowed to cool down for several minutes before transferring it to a glass/plastic jar.
- 5-15 ml of pond water is added to the jar.
- The solution is left to set for at least 4-7 days, during which time it will turn turbid, indicating microorganism growth.
- Old pots can be used for boiling, but the container used for boiling should not be reused due to potential contamination.
- The prepared hay infusion should be brought to the laboratory on the scheduled date of Activity 5.
