ORP/Redox is where it's all at and the main measured parameter when discussing wetland soils and roots, nutrients etc, it governs movement and transformations etc.
I wish the ref Redox Calomal and platinum tips where more available.
Redox is really squirrely.
This is how we test what is an optimum redox for root growth rates and this is correlated with flow and O2 diffusion from above etc.
Heating cable folks could have used this method to demonstrate that their heater cables where/where not effective, however, even after explaining it, and suggesting it, 20 years later.........not one has bothered, I have, others did, and found ranges of flow and ppm's and redox levels.
The proponents curiously have remained silent other than the stop by and and try and yell loudly that it works well "for them", but there's no demonstration of any control, any quantification etc, just they appear to grow better and take my word for this long term subtle difference in growth(which if you have a very long term subtle difference, by it's very nature, it's not really significant and prone to many errors over months/year's of growth, particularly without any control reference, no redox measures etc etc etc).
This might be preaching to the choir, however, with the link above, think about this and what's been done in wetland research and see if you find any rational for heat cables or the larger grain pore sizing with ADA's powersand providing better flow etc.
I cannot.
