Soil salinity is a global problem that greatly restricts agriculture production, and salt stress is one of the traditional ...

They include the cations Ca+2, Mg+2, K+ as well as the anions Cl–, SO4-2, B0, and NO3–. Other salts that contribute to soil salinity include Na+, CO3-2, and HCO3–. Typically, NO3– and K+ are not high ...
