Abstract
The reclamation of salt-affected soils is considered a slow process that urges the development of faster recovery strategies as a priority. The present article aimed at investigating the effect of mixing different chemical and organic conditioners on the growth of Atriplex and its salt extraction efficiency during its early growth stage. A pot experiment was conducted on saline-sodic Cambisol cultivated with Atriplex for 60 days and subjected to the following conditioner mixtures: Atriplex; Atriplex + gypsum + organic matter; Atriplex + elemental sulfur + organic matter; and Atriplex + gypsum + elemental sulfur + organic matter. The mixtures of conditioners did not affect the Atriplex growth, but caused significant increase in Na+ and Cl− contents in the dry matter of Atriplex plants. Additionally, there was an increase in the Atriplex's ability of extracting salt due to the application of the mixtures. Results suggest that the “gypsum + organic matter” mixture is preferable for a faster recovery of salts/sodium affected soils through phytoremediation by Atriplex plants, mainly due to a more significant increase in the efficiency of salt absorption.
