The Simplest Method
Evacuate your sampling bottle down to approximately 50 kPa. If the soil water tension is lower than 50 kPa, soil water solution will be extracted until vacuum and soil water tension are equalized. When the samples are collected, the bottle is evacuated again.
This portable vacuum has a rugged case and uses a powerful pump and rechargeable battery, which make it easy to collect pore water samples at remote locations.

Qualitative analysis of soil water
Benefits
Low cost
