[edit] Parameter to be measured:

Soil matric potential

[edit] Method:

Tensiometer

[edit] Equipment:

T5

[edit] Advantages:

• Small
• Very fast response
• Great resolution when used with the DL6-te Tensiometer Data logger
• Reliable

[edit] Disadvantages:

• Their small size makes them great for laboratory or flume experiments but less appropriate for field measurements.
• They have to be taken out of the soil to refill them.

[edit] What to watch out for:

• Don’t burry them too deep - you will have to dig them out (and thus disturb the soil again) if you need to refill them.
