20gon dareere ah oo haanta bakhaarka nitrogen
Haanta keydinta dareeraha ah, magaca buuxa ee haanta bakhaarka neefsashada ee dareeraha ah, waa weel si gaar ah loo isticmaalo in lagu keydiyo dareeraha dareeraha ah. Haanta kaydinta dareeraha ah waa shey farsamo oo aad u sarreeya loo isticmaalo bayoolaji, daawada, qaboojiyaha iyo meelaha kale. NITROGEN NITROGEN waa hab muhiim ah oo kaydinta dhir, iyo haamaha keydka ee dareeraha ah waa qalab muhiim u ah keydinta dareeraha ah ee loo yaqaan 'dareere nitrogen'.
Biyo-goynta dareeraha ah ee neef-qaadashada ah waxay leeyihiin qaabab kala duwan, badiyaa toosan oo toosan, oo ka mid ah kuwa haanta haanta haynta dareeraha ah ee dareeraha ah ee dareeraha ah ayaa ah kuwa ugu waaweyn. Haanta kaydinta dareeraha ah ayaa inta badan ka kooban haanta gudaha ah, qolofta kore, lakabka galka, ee lakabka kuleylka, iyo cagaha taageeraya. Qolofta dibedda ah waxay ka samaysan tahay saxan bir ah, oo haanta dhexdeeda waxaa ka samaysan bir bir ah. Waxaa jira dhexdhexaad kuleyl kuleyl ah oo u dhexeeya qolofka dibedda ah iyo haanta gudaha si loo yareeyo wareejinta kuleylka, si loo hubiyo in dareeraha dareeraha ah uu ku sugan yahay heerkulka dareeraha ah.
