Nitrate ions thiab nitrite ions hloov mus rau nitrous oxide gas thiab nitrogen gas ( N2 ). Cov hauv paus hniav nqus ammonium ions thiab nitrate ions siv los ua cov molecules xws li DNA, amino acids, thiab cov proteins. Organic nitrogen (cov nitrogen hauv DNA, amino acids, proteins) tawg mus rau ammonia, ces ammonium.

Hauv kev hwm rau qhov no, dab tsi yog txheej txheem uas ammonia hloov mus rau nitrite ces mus rau nitrate?

Nitrification yog qhov txheej txheem uas converts ammonia rau nitrite thiab tom qab ntawd mus rau nitrate thiab yog lwm kauj ruam tseem ceeb hauv ntiaj teb no nitrogen voj voog.

Tsis tas li ntawd, nitrogen hloov mus rau ammonia li cas? Kauj ruam 1- Nitrogen Fixation - Cov kab mob tshwj xeeb hloov tus nitrogen gas (N2) rau ammonia (NH3) uas cov nroj tsuag siv tau. Kauj Ruam 2- Nitrification- Nitrification yog txheej txheem uas hloov tus ammonia rau hauv nitrite ions uas cov nroj tsuag tuaj yeem noj hauv cov as-ham.

Ua li no, nitrates hloov mus rau nitrogen li cas?

Denitrification ua tiav cov nitrogen lub voj voog los ntawm hloov nitrate (NO₃^-) rov qab mus rau gaseous nitrogen ( N ₂). Cov kab mob denitrifying yog cov neeg ua haujlwm ntawm cov txheej txheem no. Cov kab mob no siv nitrate es tsis txhob oxygen thaum tau txais lub zog, tso tawm nitrogen gas rau huab cua.

Ob hom kev kho nitrogen yog dab tsi?

Cov ob hom kev kho nitrogen yog: (1) Lub cev Nitrogen Fixation thiab (2) Biological Nitrogen Fixation . Sib nrug los ntawm carbon, hydrogen thiab oxygen, nitrogen yog qhov tseem ceeb tshaj plaws macro-element hauv cov tsiaj muaj sia.
