The invasive tree staghorn sumac affects soil N 2 ‐fixing bacterial communities in north China
Plant Biology, 2019Co-Authors: Shu Wang, Mei Wei, Jiawei Zhou, Kun Jiang, Congyan WangAbstract:Soil N2 -fixing bacterial communities (SNB) can enhance soil N availability and the invasiveness of invaders. Some invaders display different degrees of invasion across different climate Regions. Given that bacterial communities may change with different climate Regions, it is important to understand soil micro-ecological mechanisms driving the successful invasion of invaders across different climate Regions. This study performed cross-site comparisons to comprehensively analyse effects of the invasive tree staghorn sumac (Rhus typhina L.) on the structure of SNB. In north China, we selected three sites within two sampling Regions (a warm Temperate Region and a cold Temperate Region). Staghorn sumac invasion did not significantly affect soil physicochemical properties and the diversity and richness of SNB. LEfSe analysis showed that numerous SNB taxa changed significantly during staghorn sumac invasion. This may be attributed in part to the selective effects of allelochemicals released by staghorn sumac via leaf litter and/or root exudates. Consequently, staghorn sumac invasion may alter the structure, rather than the diversity and richness, of SNB to facilitate its invasion process by establishing a favourable soil microenvironment in the invaded habitats. The number of species and richness of SNB under staghorn sumac invasion were significantly lower in the warm Temperate Region than in the cold Temperate Region. A possible reason for the increased diversity and richness of SNB under staghorn sumac invasion in the cold Temperate Region may be because staghorn sumac in the cold Temperate Region can provide more nutrients into the soil sub-ecosystem, presumably to support a higher diversity and richness of SNB via the nutritional requirements of SNB. The changed structure of SNB under staghorn sumac invasion, especially across different climate Regions, may play an important role in its successful invasion across most Regions of north China.

Changes in the pH, EC, available P, SOC and TN stocks in a single rice paddy after long-term application of inorganic fertilizers and organic matters in a cold Temperate Region of Japan
Journal of Soils and Sediments, 2017Co-Authors: Weiguo Cheng, A. T. Padre, Hiroyuki Shiono, Chizuru Sato, Toan Nguyen-sy, Keitaro Tawaraya, Katsumi KumagaiAbstract:Purpose The objective of this study was to determine the changes in the main soil chemical properties including pH, electrical conductivity (EC), available phosphorus (P), soil organic carbon (SOC) and total nitrogen (TN) stocks after long-term (31 years) additions of two types of organic matters—rice straw and rice straw compost, combined with NPK fertilizers in single rice paddy in a cold Temperate Region of Japan. Materials and methods A long-term experiment on combined inorganic fertilizers and organic matters in paddy rice cultivation began in May 1982 in Yamagata, northeastern Japan. After the 31st harvest, soil samples were collected from five treatments [(1) PK, (2) NPK, (3) NPK + 6 Mg ha^−1 rice straw (RS), (4) NPK + 10 Mg ha^−1 rice straw compost (CM1), and (5) NPK + 30 Mg ha^−1 rice straw compost (CM3)] at five soil depths (0–5, 5–10, 10–15, 15–20, and 20–25 cm). Soil chemical properties of pH, EC, available P, SOC, and TN were analyzed. Results and discussion The pH decreased significantly only at the higher compost rate of 30 Mg ha^−1, while EC increased in all the organic matter treatments. Available P significantly increased in the CM1 and CM3 treatments by 55.1 and 86.4 %. The amounts of SOC stock increased by 67.2, 21.4, and 8.6 %, and soil TN stock by 64.1, 20.2, and 8.5 % in CM3, RS, and CM1, respectively, compared to NPK treatment. Conclusions Significant changes in soil properties were observed after 31 years of organic matter applications with reference to PK- and NPK-fertilized rice paddy soils. A significant decrease in pH was observed with the application of a high rate (30 Mg ha^−1) of rice straw compost but not with the conventional rate of 10 Mg ha^−1. However, EC increased significantly relative to that of the PK- and NPK-fertilized plots in all the organic matter treatments. Available P significantly increased in the CM1 and CM3 treatments by 55.1 and 86.4 %. The amounts of SOC stock expressed as a percentage of total C applied to the soil were higher from 10 Mg ha^−1 compost (28.7 %) than that from 6 Mg ha^−1 rice straw (17.4 %), indicating a more effective soil organic C accumulation from rice straw compost than that from original rice straw.
