Sample Preparation
Adjust the moisture content in the soil.
A compost must be moist to allow microorganisms activation.
| - |
If compost is too dry, no microbial activity is possible: compost transformation process (composting) is stopped. |
| - |
If compost is too wet, unwanted microbial processes occur in anaerobic conditions (= absence of oxygen) and the compost may eventually have a bad smell and contain phyto-toxic acids. |
A simple test to check compost moisture content is called 'punch test'. After taking a handful of compost, squeeze it hard and then open your hand.
| - |
If the compost is too dry, it will then fall apart. If the moisture content is normal, the compost remains compact. |
| - |
If the compost is too wet, the water will splash out of the hand when you squeeze the compost. |
Depending on the situation, necessary measures, such as adding water or covering the compost, can be taken.
Once the soil has been prepared with the correct humidity, it is necessary to determine the dry mass fraction.
Finally, the volume occupied by the soil (after humidity adjustments) must be determined as follows:
In a 200/250 ml cylinder add 100 ml of deionized water and add 50/100g of medium.
After mixing, the final volume, subtracted from the volume of the water, is the volume occupied by the soil.
Analysis Procedure
| 1.
| Set the incubator temperature to the desired value, 20-25¡ÆC. We set the tests at 25¡Æ¡¾1¡ÆC. |
|
| 2.
| Connect the Wireless DataBox¢â and fill in the RESPIROSoft¢â software database. |
|
| 3.
| Weigh 50 - 200g of well-mixed soil in a beaker and transfer it to a 1-liter flask |
| 4.
| Introduce about 6 pellets of KOH into the alkali collector |
| 5.
| Screw the RESPIROMETRIC Sensors onto each bottle and tighten |
| 6.
| Place the system in the incubator at the test temperature. |
| 7.
| Wait at least 3 hours to reach the correct test temperature and to develop the typical initial pressure increase.
| ¡Ü
| This growth is due to vapor pressure and air flask heating |
| •
| To remove the additional pressure, we recommend venting test bottles to the atmospheric pressure (by briefly loosening the ring nut). |
|
| 8.
| Press START and run the test for at least 15 days. |
