Incubation experiment of sediments indicated that short-term interconversions between forms of nitrogen are relate to the content of oxygen in water column and that the nitrogen in sediments can transform into dissolved inorganic and organic nitrogen. 沉积物孵化实验表明,水体中无机氮各种形态之间的转化和水体中含氧程度有关,沉积物中的氮可以向无机态氮及有机态氮转化。
