Hello all..
Asking all you guys, is any low cost technology available to control the TDS of irrigation water ?
Farmers going through many hurdles. One of then is salty water. Salty/ saline water affects on productivity and also on the health of land. But farmer has no any option to replace the available water source. Pls share your ideas and views.

    Conventional irrigation is very wasteful of water. A lot of the water seeps down into earth or evaporates. Low cost options are few.
    If we can have an impervious layer under the soil at a depth where the roots of the plant (rice, wheat etc) do not reach, the seepage loss can be reduced. If this can be combined with some form of drip irrigation with active monitoring of soil moisture, losses can be reduced further. If the total water demand is reduced, then some form of water treatment can be considered. Even then the TDS is converted into some form of precipitate, which over time may pose disposal problems.
    In short, there is no simple solution.
