In order to investigate the effects of mycorrhizal symbiosis on some soil hydraulic properties and nutrients uptake by spring barley, a greenhouse experiment was conducted based on a completely randomized blocks design with four replications, using two mycorrhizl fungi including Glomus intraradices (GI) and Glomus etunicatum (GE) and non-mycorrhizal (control) treatments, in an alkaline coarse-textured soil. Results showed that GE and GI significantly increased (P< 0.01) field capacity (FC) water content by 24.7 and 12.6%, permanent wilting point (PWP) water content by 20.1 and 11.1%, available water capacity (AWC) by 27.1 and 13.3%, micropores by 14.1 and 5%, mesopores by 27.8 and 20.8% and decreased macropores by 17.3 and 9.5% and saturated hydraulic conductivity by 88.2 and 68.8% relative to the control, respectively. Also, GE and GI fungi significantly increased (P< 0.01) uptake of phosphorus in barely seeds by 44.1 and 20.3% and in stem by 181 and 50.6% and potassium in seeds by 290.8 and 167.9%, respectively. It is concluded that mycorrhizal symbiosis, as a biological and sustainable method, improved hydraulic and chemical quality of the alkaline coarse-textured soil. |
