Shrub encroachment has significant impacts on carbon (C) and nitrogen (N) dynamics of grassland ecosystems, but, how it influences soil organic C (SOC) and soil total N (STN) stocks of grasslands is not well documented, especially in deep by: 5. Nodulation, nitrogen fixation, and nutrient concentrations were determined in the alfalfa plants and soils after 12 wk. Compared with the antibiotic-free control, symbiotic nitrogen fixation increased significantly in soils mixed with manure containing 2 and mg kg −1 oxytetracycline ( and % increase, respectively) and a mixture of Author: Anne Ostermann, Peter E. Mortimer, Rongcai Huang, Lu Ma, Dengpan Bu, Jianchu Xu, Jianchu Xu.
Denitrification is a microbial process that occurs primarily in surface layers when soils are saturated with water. Soil bacteria convert nitrate to both nitrous oxide (N 2 O) and N N 2 (two atoms of nitrogen bonded together) is the most abundant gas in the atmosphere and not of environmental concern, each molecule of N 2 O gas—largely generated by denitrification, with . Nitrogen (N) is one of the most important elements for plant growth and hence it is vital for ecosystem’s primary production .In the background of global climate change, understanding soil N balance in agricultural soils is important for sustaining the development of modern agriculture and mitigation of climate change considering the substantial contribution made by agriculture Author: Ling Zhang, Xiaojun Liu.
An efficient nitrogen fertilizer recommendation for plant production depends on the amount of N supplied by the soils. A study to investigate the characteristics of net N mineralization in typical paddy soils in an important rice production area of China was conducted on aerobic soils for d of incubation at 25° by: 2. The nitrogen cycle in soil is an integral part of the overall cycle of nitrogen in nature. Under natural conditions, gains in nitrogen occur through fixation of elemental nitrogen by microorganisms, and from the accession of ammonia and nitrate in rain water; losses occur through crop removal, leaching, and volatilization.

The annual consumption of fertilizer nitrogen in the world has reached 70 million tons, and China has an annual consumption of more than 15 million tons and is the largest fertilizer nitrogen consumer in the world.
However, the efficiency of nitro gen fertilizer is low and losses are : Paperback. Nitrogen is one of the most important nutrients for plant growth and the applica tion of fertilizer nitrogen is playing an important role in agricultural production.

He has been conducting studies on nitrogen (N) cycling, in particular on the source, fate and impacts on soil acidification, eutrophication and greenhouse gas emission in major Chinese croplands.
He has published more than peer-reviewed SCI papers in a number of leading international journals including Nature, Science and PNAS. In dryland soils, nitrate N is the major form for plant uptake, and a large portion of nitrate N entering plants is reduced by nitrate and nitrite reductases and participates in a series of metabolic processes, being assimilated to amino acids and finally to by: As an essential nutritional element, nitrogen (N) plays extremely important roles in agriculture.
It is needed by plants in large amounts while almost all soils worldwide are deficient in this element, resulting in a great gap between its demand and its supply from soil. The Red Soils of China. Red soils are highly leached soils of the humid tropics having a high content of sesquioxides.
In the current system of U. Soil Taxonomy, red soils are usually designated under the orders of Oxisols, Ultisols, and occasionally Alfisols, Mollisols. The book’s main objectives are: (1) to explain in detail the role of C and N cycling in sustaining agricultural productivity and its importance to sustainable soil management; (2) to show readers how to restore soil health with C and N; and (3) to help them understand the matching of C and N cycling rules from a climatic perspective.
The processes and characteristics of nitrogen mineralization in paddy soils of the Taihu Region of China were studied with day anaerobic incubatio. Nitrogen may well be the most studied nutrient in agricultural systems, but how well do we understand it and apply that knowledge.
In Nitrogen in Agricultural Systems new research tools and advanced management concepts are presented from a holistic perspective that emphasizes the complexity of the nitrogen cycle in the soil-plant-water system.

national soil survey of China [National Soil Survey Office,a, b, a, b,]. This database is composed of records of typical soil profiles across China (see Figure 1), each of which represents soil species in the Genetic Soil Classification of China (GSCC) [Shi et al., b]. Each soil profile is divided into Cited by: More than 79% of soil carbon and 51% of soil nitrogen at a depth of 0– cm were stored in the upper 50 cm of the soil pool.
In the vegetation layer, due to the similar tree biomass carbon and nitrogen stocks, there were no significant differences in carbon and nitrogen stocks among the three types of larch forest : Ruihan Xiao, Xiuling Man, Beixing Duan.

Cropland soils are turning acid from the overuse of nitrogen fertilizers, decreasing productivity, polluting the environment, and contributing huge amounts of greenhouse gas emissions; researchers recommend reducing fertilizer use, but have not considered phasing it out altogether by.
Nitrogen exists in the soil system in many forms, and changes (transforms) very easily from one form to another. The route N follows in and out of the soil system is collectively called the nitrogen cycle (Figure 1).
The nitrogen cycle is biologically influenced.China, with its vast and diverse climatic conditions, has a wide variety of soils. Indeed, all the soil types of the Eurasian continent, except the soils of the tundra and the highly leached podzolic-gley soils of the northern taiga (boreal forest), are found in China.Many of the soil tests evaluated in the book are used throughout the world.
