Cov nitrogen voj voog yog tus txheej txheem uas nitrogen yog hloov dua siab tshiab ntawm nws ntau hom tshuaj. Qhov kev hloov pauv no tuaj yeem ua tiav los ntawm cov txheej txheem lom neeg thiab lub cev. Cov txheej txheem tseem ceeb hauv cov nitrogen voj voog suav nrog kho , assimilation, ammonification, nitrification, thiab denitrification.

Ib yam li ntawd, tib neeg nug, dab tsi yog lub voj voog nitrogen piav qhia nws?

Cov nitrogen voj voog yog biogeochemical lub voj voog los ntawm qhov nitrogen Nws hloov mus rau hauv ntau hom tshuaj raws li nws circulates ntawm huab cua, terrestrial, thiab marine ecosystems. Cov txheej txheem tseem ceeb hauv cov nitrogen voj voog suav nrog kho , ammonification, nitrification, thiab denitrification.

Tsis tas li ntawd, 7 kauj ruam ntawm lub voj voog nitrogen yog dab tsi? Lub voj voog nitrogen muaj ntau theem:

  • Nitrogen fixation. Atmospheric nitrogen tshwm sim feem ntau hauv daim ntawv inert (N2) uas ob peb kab mob tuaj yeem siv tau; yog li ntawd nws yuav tsum tau hloov mus rau ib qho organic - los yog tsau - daim ntawv nyob rau hauv ib tug txheej txheem hu ua nitrogen fixation.
  • Nitrification.
  • Assimilation.
  • Ammonification.
  • Denitrification.

Hauv qhov no, 5 kauj ruam ntawm nitrogen voj voog yog dab tsi?

Feem ntau, lub voj voog nitrogen muaj tsib kauj ruam:

  • Nitrogen fixation (N2 rau NH3 / NH4 + lossis NO3-)
  • Nitrification (NH3 rau NO3-)
  • Assimilation (Kev koom ua ke ntawm NH3 thiab NO3- rau hauv cov ntaub so ntswg lom)
  • Ammonification (organic nitrogen tebchaw rau NH3)
  • Denitrification (NO3-N2)

Cov txheej txheem ntawm nitrogen voj voog yog dab tsi?

Cov txheej txheem hauv nitrogen voj voog . Tsib lub ntsiab txheej txheem voj voog nitrogen Los ntawm biosphere, huab cua, thiab geosphere: nitrogen fixation , nitrogen txhawb nqa los ntawm kev loj hlob ntawm lub cev, nitrogen mineralization los ntawm kev lwj, nitrification, thiab denitrification.
