Effects of Applying Lime and Calcium Montmorillonite on Nitrification Dynamics in Acidic Soil WANG Mei, JIANG Xian-jun * (College of Resources and Environment, Southwest University, Chongqing 400716, China) Abstract: Soil acidification is known as a natural and slow process along with clay mineral weathering. In recent years however, with inten原 sive soil utilization in agriculture, soil acidification has increased dramatically and nitrification of ammonium nitrogen fertilizer is one of the main contributors to soil acidification. Lime application is the traditional practice to improve acidic soils but it often makes the soil acidic a原 gain leading to soil compaction in most cases. Montmorillonite is the main clay mineral component of alkaline or neutral soils, more so it is known to undergo further weathering processes during soil acidification. The laboratory-based incubations were used in this study, and nitri原 fication was measured while kinetic curves were fitted to check the effects of decreasing soil acidity by lime(Ca-OH)and montmorillonite (Ca-M)on nitrification of the acidic soil. The results showed that significant nitrification was observed both in Ca-OH and Ca-M treatments, and the nitrification process was fitted in the first-order kinetic model, NNO3=N0+Np (1-exp(-k1t))(P<0.001). The net nitrification rate of Ca-OH treatment(3.429 mg·kg-1·d-1)was significantly higher than that of Ca-M treatment (2.381 mg·kg-1·d-1). The potential nitrifi原 cation rate(V p)were 6.42, 8.58 mg N·kg-1·d-1 at pH 5.7 and 6.2 respectively, and the average nitrification rate(V a)of Ca-OH treatment were 2.71, 3.88 mg N·kg-1·d-1 respectively, which were significantly greater than those of Ca-M treatment(V p were 3.40, 4.56 mg N·kg-1·d-1 and V a were 2.36, 3.04 mg N·kg-1·d-1 at pH 5.7 and 6.2 respectively).

Impact of Flaveria bidentis Litter on Communities of Invertebrates in Soil in Different Habitats YAN Jing1,2, ZHANG Rui-hai1, SONG Zhen1, ZHANG Guo-liang1, LIU Yu-sheng2, FU Wei-dong1* (1.Institute of Agricultural Environment and Sustainable Development, Chinese Academy of Agricultural Sciences, Beijing 100081, China; 2.College of Plant Protection, Shandong Agricultural University, Tai'an 271018, China) Abstract:An investigation was conducted to explore the impacts of Flaveria bidentis litter on the communities of invertebrates in soil in three different habitats including forestland, wasteland, and ditches. A total of 54 315 individuals were captured in three habitats on October 23rd by cutting ring(diameter is 20 cm, height is 10 cm), which is divided into three sampling layers in this study. All of the individuals belong to 2 phyla 10 classes 17 orders, among which Arachnoidea and Collembola were the dominant orders in three habitats, and the relative abundance of other species were smaller. F. bidentis litter could provide the better habitats and food sources for invertebrates in soil, such as Arachnoidea, Collembola, Psocoptera and so on, thereby affecting their structure and diversity of community of invertebrates in soil which mainly related to growth conditions of F. bidentis community, which is characterized by its weaker growth conditions in forestland but stronger growth in wasteland land and ditches. In summary, F. bidentis plants and their litter provided habitat and concealment for the dominant species, and significantly changed content of nitrogen, phosphorus, potassium and organic matter in surface humus soil after the invasion of F. bidentis in three habitats, which cause the increasing of diversity of invertebrates in soil and also it trends to increase for the diversity of invertebrates in liter from top to bottom. Thus it laid a foundation for the influence of decomposition rate in F. bidentis litter on the diversity of invertebrate communities in soil.
