Pụtara nke okirikiri nri
Usoro nri nri na-ezo aka na mgbasa nke ụfọdụ nri dị ka nitrogen, carbon, sọlfọ na mmiri na okike.
Pụtara Nitrogen Cycle
Nitrogen okirikiri na-agụnye usoro mgbagwoju anya nke a na-esi na ya gbakwunye nitrogen ma wepụ ya n'ala. Ọ bụ a usoro mmeghachi omume na-egosi ụzọ dị iche iche a na-esi etinye nitrogen ma wepụ ya na ikuku na ala.
Usoro nhazi nitrogen na-agụnye ihe ndị dị n'ime ala nke na-agbakwunye ntakịrị nitrogen na ala.
Nitrogen okirikiri gụnyere usoro ndị a:
1. Ndozi nitrogen Symbiotic: Ụfọdụ nje bacteria dị ka rhizobium leguminosarium nke na-ebi na mgbọrọgwụ nodules nke leguminous osisi nwere ike idozi ikuku nitrogen ozugbo n'ime osisi. Osisi ahụ na-enye carbohydrate maka nje bacteria na-eji ebe nje bacteria na-enye osisi ahụ na nitrogen jikọtara ọnụ.
2. Mwepu eletriki: Enwere ike itinye nitrogen n'ime ala n'oge àmụmà na égbè eluigwe. Nitrogen dị n'ikuku na-ejikọta ya na ikuku oxygen na-emepụta nitric oxide ma ọ bụ nitrogen (ii) oxide nke na-aga n'ihu na-enweta oxidation ka ọ bụrụ nitrogen dioxide ma ọ bụ nitrogen (iv) oxide.
3. Ndozi nitrogen na-abụghị symbiotic: Ụfọdụ nje bacteria dị ka Azoyobacter na Clostridium na-ebikwa n'ime ala ma nwee ike itinye nitrogen ikuku n'ime ala ma ọ bụ ikuku ma ọ bụ anaerobically.
4. Ammonification na nitrification: Usoro nke gụnyere iguzobe ogige ammonium site na ndị nwụrụ anwụ na ire ure nke osisi na anụmanụ na ihe mkpofu ha dị ka mmamịrị na nsị bụ. akpọ ammonification. A mmeghachi omume ọzọ a maara dị ka nitrification gụnyere ntụgharị nke ogige ammonium nke mbụ na nitrite site na nitrifying nje bacteria. akpọ nitrosomonas. A na-agbanwe nitrites ndị a site na oxidation ka ọ bụrụ nitrates site na nje bacteria ọzọ akpọ nitrobacter. Osisi nwere ike naanị nuo nitrates sitere na ala.
5. Ngwọta eze: Nke a bụ usoro nke gụnyere ntụgharị nitrate na gas nitrogen site na ụfọdụ nje bacteria. Ngwongwo nitrogen a kpụrụ nwere ike ịgbaba n'ikuku.
Cheta na: Denitrification bụ naanị isi ọkwa nke nitrogen nwere ike ịpụ na ala ebe usoro ndị ọzọ gụnyere itinye nitrogen n'ime ala.
