    The effect of saline water on the growth of trees
    Hello, my dear

    How are you? I am very gladeful if your are in a position to provide me some scientific information about the effect of saline water (12 dS/m) on the total nitrogen, amount of proline, total chlorophyll of three desert trees (Prosopis cineraria, Acacia tortilis and Ziziphus spina-christi).

    With the best regard,

    I don't know much about those three species in general, but I can tell you that once you have EC values above 4 you start a soil officially has salinity problems. In terms of nutrient availability, salts are composed of a cation and an anion (Na+ Cl-) and often times, saline soils are also sodic (too much Na+) Having too much sodium makes necessary cations less competitive for uptake and causes nutrient deficiencies.
    It looks like you have some pretty saline soils with values at 12 ds. Salt accumulation becomes visible around values of 20, sometimes less, sometimes more, so unless those plants are specifically salt tolerant, you will have some problems. Also, you can easily flush the soil free of these salts. Just water it, salts dissolve very easily and are very soluble.

    I hope this was of some assistance. If you have any more questions, especially soil specific ones, let me know.
