Divergence of nutrients, salt accumulation, bacterial community structure and diversity in soil after 8 years of flood irrigation with surface water and groundwater.

ABSTRACT: Irrigation with saline groundwater has become necessary to overcome freshwater scarcity in the agricultural industry in arid areas. However, the effects of long-term saline groundwater irrigation on soil salinity and bacterial diversity have rarely been examined. In this study, a Lycium ruthenicum field was divided into two parts and subjected to flooding irrigation with saline groundwater (pH 7.81, total salinity 0.95 g L^-1) and surface water (pH 7.76, total salinity 0.36 g L^-1) for 8 years. After 8 years of irrigation, the soil salinity and salt ion content (i.e., Na⁺, Mg²⁺, K⁺, Ca²⁺, Cl^- and CO₃^2-) in the groundwater irrigation group were significantly greater than those in the surface wat
