MB-N and total N are significantly passively correlative(P0.01)for all other land-use types.The order of N surplus for the different land-use types is:double cropping paddy field(105.0kg/hm2·a)single cropping paddy field(75.1kg/hm2·a)dry farming paddy soil(64.5kg/hm2·a)dry land(51.9...
China Abstract Nitrogen (N) deposition significantly affects the soil carbon (C) cycle process of forests. However, the influence of dif- ferent types of N on it still remained unclear. In this work, ammonium nitrate was selected as an inorganic N (IN) source, while urea and glycine...
2. Nitrogen cycle: Nitrogen is an essential component of life. Living organisms cannot consume nitrogen directly instead it has to be converted into other organic compounds. Nitrogen is converted into other forms in different ways and they are: Nitrogen-fixing bacteria convert atmospheric nitrogen to...
Temperature sensitivity of soil respiration (Q10) is an important mechanism for the possible feedback between global carbon cycle and climate system. Knowledge of how crop types and nitrogen (N) fertilization affectQ10is critical for estimating soil respiration and carbon cycling in agro-ecosystem. A...
Detritivores is branch of decomposer. It plays an essential role in most biogeochemical cycles like thenitrogen cycle,carbon cycle, and phosphorous cycle. Examples of detritivores are insects (such as mites, butterflies, mites), flies, crabs, millipedes, woodlice, earthworms, etc. ...
Soil provides a home for many organisms, especially microorganisms. Soil also provides and has important gas content. Soil takes part in all major biogeochemical cycles such as the phosphorous cycle, nitrogen cycle, and carbon cycle.View Video Only Save Timeline Video Quiz Course 935K views...
To examine the influence of microbial carbon (C) availability on the internal soil nitrogen (N) cycles under moder and mull forest floor types within the same slope sequence, surface mineral soils (0-5 cm depth) taken at upper (moder-type forest floor) and lower (mull-type forest floor) ...
University of Hawaii, Honolulu, HI, USA A diagnostic model based on biomass and growth was used to assess the relative contributions of filamentous nonheterocystous Trichodesmium and unicellular cyanobacteria, termed Groups A and B, to nitrogen fixation at the North Pacific Station ALOHA over a 2...
