Salinity Tolerance Screening Facility

Soil salinity refers to a state where dissolved constituents in interstitial water concentrate beyond the needs of the plants rooted in the soil. Salinity levels in soils can range from very slight to very severe within a few meters. Such variability makes it impossible to evaluate the salt tolerance of crops in the field.

Saveer’s engineers and scientists have overcome this difficulty by fabricating an environmentally- controlled testing facility.

Our designed and fabricated environmentally-controlled salt-tolerance testing facility to screen agricultural and horticulture crops comes with features like large grow tanks which can evaluate crops from emergence through maturity.

Salt tolerance response functions have already been determined for various crop varieties of wheat, barley, spring wheat, field pea and a number of perennial grasses. Opportunity exists for many more crops and different varieties.


  • Thermally-controlled greenhouse which permits year-round testing.
  • The facility within the greenhouse is ventilated by: (1) full length, gable-top louvers which open and close in relation to set point temperatures, outside wind speed and direction, and gable-to outside temperature differences; (2) inside air circulation fans; and, (3) automated fans and evaporative coolers drawing outside air when needed.
  • A programmable logic controller actuates the facility’s lightning, heating, ventilation and ambient temperature monitoring.
  • The controller also automatically triggers Fertigation, replacement of supply water lost by evaporation and maintenance of brine concentration.
  • The facility offers simultaneous testing of crops at three different growth stages: germinating seeds in a growth chamber, seedlings in sand pots, and maturing plants in sand tanks. Seeds are placed in quartz sand where the roots develop and anchor the plants. Nutrients and salts in solution periodically bathe the roots following preset irrigation and drainage schedules.
