Hello Stephen, I irrigate with my pond water which if I recall has around 30-40ppm of chloride but I think the sodium is under 10ppm. I’ll have to check the water analysis on which is in my this be thread somewhere. I’m at work right now so I’ll check later. The only be things in I be typically run through the fertigation are rejuvenate, SeaShield, SeaStim, biologicals,… Occasionally I have run some potassium sulfate or potassium silicate or magnesium sulfate or Urea through but not by in this crop cycle. I’ve been doing some foliars primarily, manganese, iron, Urea but I stopped about two weeks before pulling samples as I wanted to see what the plants are getting naturally. The sweet corn has excessive nitrate probably due to it being the only area I added chicken manure (well composted), and I assume the sodium is higher in that spot because of this as well. I do not know what my chloride level is in the soil but sodium is under 1% base saturation. I have soil tests in this thread somewhere.
