Soil health indicator: soil compaction PSI reading using a dial penetrometer
A way to assess soil compaction. Soils become more open/easier to penetrate as health improves. Lower compaction (tightness) is associated with well structured soil – as soil structure in the long term is a product of biological activity.
Tip: you may wish to ask a friend to video the process of inserting the penetrometer into the soil. This will mean you don’t have to remember the reading you get.
- Soil Penetrometer (dial)
What to record in the Soilmentor app:
- Decide whether you want to test the field more generally (under the W walk category), or repeatedly test a specific sample site over time (using the GPS feature to find the same sample location to test the ground).
- Push penetrometer into soil with straight arms, as far as possible
- Record on the app the highest value you see as you insert probe (videoing the process can be helpful if practical)
- Value PSI
