Water ppms
Folks,
The content of the ppms' in the tap water is critical to understand.
300 ppm of calcium is one thing. 300 ppm of sodium is another. It is important not to just make statements about ppm's without knowing what those ppm's are made of.
Reading up about the SAR concept in water analysis might be a bit revealing.
I have farmed with water that everyone swore was salty, and yes it had quite a bit of sodium. But what saved the crop was the amount of calcium present along with the sodium.
This is also important to realize that without enough calcium, it is very easy for the plants to become over sensitive to potassium etc. only because there is not enough calcium present.
