If thisnitrogen cyclerepeated elsewhere, many of the world's forest won't be absorbing much CO 2. 如果这种氮循环不断重复进行, 那么世界上很多森林都不能再吸收二氧化碳. 期刊摘选 英英释义 Noun 1. the circulation of nitrogen; nitrates from the soil are absorbed by plants which are eaten by anim...
The nitrogen cycle in the broadbalk wheat experiment: 15N-labelled fertilizer residues in the soil and in the soil microbial biomass A single pulse of 15N-labelled fertilizer was applied in spring as NH 4NO 3 to each of four plots on the Broadbalk Continuous Wheat Experiment. Wheat has been...

In the plot receiving 192 kg N ha−1 yr−1, labelled biomass N declined from 5.69 kg ha−1 at the first harvest, to 4.50 at the second, to 3.35 at the third and to 2.35 at the fourth. In a subsidiary experiment, more N was retained in the soil at harvest when the ...
The nitrogen cycle, in which atmospheric nitrogen is converted into different organic compounds, is one the most crucial natural processes to sustain living organisms. During the cycle, bacteria in the soil process or "fix" atmospheric nitrogen into ammonia, which plants need in order to grow. Ot...
In the soil N cycle, the rate-limiting step of microbial decomposition of organic matter is the depolymerization of proteins to oligopeptides and amino acids by extracellular proteases, rather than the subsequent mineralization of amino acids to ammonium1,2,3. The products of the depolymerization pro...
Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction. ...
