Irrigation

Question for you who irrigate in the dry country. Some years ago I read that farmers in the dry states who irrigated from streams had to tile the fields so that the irigation water would wash the salts out. As I understood it, the streams would pick up salt as they flowed across the land and continued use of that water would get the fields too salty to grow crops. The tile would take the water and salt out of the field and downstream.

Is this true of all the streams in the irrigated country?

Does irrigation water from wells have the same problem?

I'm in the South East and I don't irrigate.(well, it was a dry year and I irrigated the garden. I probably put as much water per stalk of corn as WyoDave did for his corn. Let me tell you, that watering out of a faucet is for the birds. Did have a garden though), Over in the flat coastal plain they will sometimes drill a well and use center pivot irrigation. Sometimes they will pump from a pond or a swamp. I can't see salt buildup there because rainfall over the winter would wash it out. I doubt if the wells will pull the water table down for long because of the winter rains.
