aggregate related changes in soil microbial communities under different ameliorant applications in Saline Sodic Soils
Geoderma, 2018Co-Authors: Shasha Luo, Lei Tian, Shaojie Wang, Zhichun Wang, Shaohua Shi, Fan Yang, Chunjie TianAbstract:Abstract Soil ameliorants can improve soil physico-chemical properties and activate microbial communities in Saline-Sodic Soils. However, there has been less focus on how aggregate fractions affect soil microbial communities under different ameliorant applications. Here, we used the phospholipid fatty acid (PLFA) analysis to explore the effects of soil ameliorants on microbial communities within mega-aggregates (diameter of >2 mm, ME), macro-aggregates (diameter of 0.25–2 mm, MA), and micro-aggregates (diameter of ME > MI. Meanwhile, the proportional abundance of arbuscular mycorrhizal fungi (AMF) varied between different aggregate fractions as follows: ME > MA > MI. Additionally, the DG treatment significantly enhanced the soil aggregate stability by increasing the AMF abundance, AMF/saprotrophic fungi ratio, and SOC content of the MI. Furthermore, soil microbial groups were highly correlated with soil SOC (P 0.25 mm diameter (P

grass and maize vegetation systems restore Saline Sodic Soils in the songnen plain of northeast china
Land Degradation & Development, 2018Co-Authors: Shasha Luo, Jianfeng Zhang, Lei Tian, Chunling Chang, Shaojie Wang, Xue Zhou, Lam-son Phan Tran, Chunjie TianAbstract:Establishment of an appropriate vegetation system for reclamation of Saline-Sodic Soils requires studies for specific salt-affected region(s). The phytoremediation of Saline-Sodic Soils has not been well documented in the Songnen Plain of northeast China. Thus, in this study, we aimed to investigate the effects of grass (G) and maize (Zea mays L.; M) vegetation systems, which were established for 5 years, on soil properties of 10 typical Saline-Sodic sampling sites across the Songnen Plain, in comparison with respective nonvegetated areas that were used as controls (CK) for the evaluation of variability among the sampling sites. Physicochemical properties, such as soil moisture, bulk density, porosity, saturated hydraulic conductivity, aggregate stability, pH, electric conductivity, total salt, organic C, total N, and C/N ratio, were analyzed. G and M vegetation significantly produced a 108% and 153% improvement in soil quality, respectively. Additionally, metagenomic analysis of the soil bacterial community revealed that vegetation enhanced the ability of the bacteria to survive in Saline-Sodic Soils, relative to the control. The composition of the bacterial community was highly correlated with all of the soil physicochemical properties. G vegetation had better effects than M vegetation in enhancing soil organic C, total N and aggregate stability, whereas M vegetation more favorably adjusted soil pH, physical structure, and bacterial community than G vegetation did. Collectively, these findings demonstrate that M vegetation has a greater impact than G vegetation on repairing Saline-Sodic Soils in the Songnen Plain of northeast China.

short term carbon mineralization in Saline Sodic Soils
Biology and Fertility of Soils, 2012Co-Authors: Raj Setia, Deepika Setia, Petra MarschnerAbstract:Previous studies have shown that carbon (C) mineralization in Saline or Sodic Soils is affected by various factors including organic C content, salt concentration and water content in Saline Soils and soil structure in Sodic Soils, but there is little information about which soil properties control carbon dioxide (CO2) emission from Saline-Sodic Soils. In this study, eight field-collected Saline–Sodic Soils, varying in electrical conductivity (ECe, a measure of salinity, ranging from 3 to 262 dS m−1) and sodium adsorption ratio (SARe, a measure of Sodicity, ranging from 11 to 62), were left unamended or amended with mature wheat or vetch residues (2% w/w). Carbon dioxide release was measured over 42 days at constant temperature and soil water content. Cumulative respiration expressed per gram SOC increased in the following order: unamended soil
