Place in the base of each vessel before adding soil and water. |
| 2 | Air-dried sieved calcareous soil | variable VARIABLE | Add a layer approximately 1 cm deep to each vessel. | |
| 3 | Deionized water | variable VARIABLE | Add carefully to a depth of 7-10 cm above the soil layer. |
Preparation
- Place approximately 0.01 g ammonium magnesium phosphate in the base of each vessel.
- Place a 1 cm layer of air-dried, sieved calcareous soil in each vessel.
- Optionally add one grain for organisms that benefit from it.
- Add deionized water carefully to a depth of 7-10 cm, then plug or cover.
- Autoclave at 15 psi for 15 minutes on each of two consecutive days.
- Let stand for at least one further day before inoculation.
