Why water should be used judiciously ?

उत्तर
Water should be used judiciously because if water is supplied in more than adequate amount, it may harm the growth of the crop plants. If there is less water supply, then the seeds of crop plants will not germinate. Also, if water is supplied in excess, it will cause water logging and soil salinity that will ultimately lead to the death of crop plants by limiting the soil aeration.
