I have a lot of sodium in my water. I have nothing but problems when I water my trees and garden. The ground gets very hard and the plants don't seem to thrive. I'm beginning to believe that the sodium is causing the soil particles to break apart. I know calcium has the opposite effect, causing the soil the flocculate. My question is, is there some way to treat my water to make it better for my watering? I don't have access to any water source other than the well water I am currently using.
