total organic nitrogen

基本解释

The content of total nitrogen, organic nitrogen, total phosphorus and phosphorus types in the sediment were obviously decreased with depth.
沉積物中全氮和有機氮隨深度增加而明顯降低。
Results showed that soil total nitrogen and organic nitrogen fractions were significantly influenced by long-term application of chemical fertilizer and manure.
結果表明，長期施用化肥和有機肥對土壤全氮和土壤有機氮組成有顯著影響。
The result showed that the contents of the total nitrogen organic matter and available nitrogen in the soil gently increased in 2005, but were fluctuated at a certain level in 2006.
土壤速傚磷和土壤速傚鉀與其它土壤養分指標相比變化幅度較大且趨勢不一致，土壤速傚磷在2005年有先上陞後下降的過程，而在2006年表現爲較爲平緩的上陞。
