I’m growing lemons and limes near Vancouver BC on the 49 parallel. I clearly have a deficiency. Can anyone confirm what’s missing? Is this due to environmental stresses? What do I do?
They’re grown in a greenhouse where I keep temperatures above freezing. They produced prolifically but fruit size was quite small.

Many thanks. It’s going to take awhile to sink into my old brain. I’ll just keep plugging away at it. let it marinate.

No, resistivity is another way to measure electrical conductivity or TDS. This measures how quickly a material can transfer electrons. Whereas voltage measures the full potential of exchanging electrons.

While the particular video and device are being presented in reference to corrosion potential for pipelines, I’m wondering if the techniques and instruments shown are how “redox” is measured, though they call it “Soil Resistivity”.

Yes, it is difficult and expensive to test Eh. I don’t know of a Farm that does more on site testing than us, and we have tinkered with Eh but discontinued because it is difficult and expensive.
However! Understanding how it works is still probably the most important thing for you to understand about soil dynamics. I say that without…
