denitrification 1. The loss of nitrogen from soil by biological or chemical means. It is a gaseous loss, unrelated to loss by physical processes such as through leachates. 2. The breakdown of nitrates by soil bacteria, resulting in the release of free nitrogen. This process takes place under anaerobic conditions, such as are found in water-logged soil, and it reduces soil fertility [di:ˌnaitrifi'keiʃən] n
environ.	脱氮作用 (1. 经由生物处理或化学方式去除土中含的氮。 是一种汽化式的散失，而非经由物理过程如渗漏的流失。 2.经由土壤中的细菌分解硝酸盐而释放出自由氮。 此种过程常发生于厌氧环境下，如浸泡在水中的土地；会降低土中养份。)
