Amathangi e-nitrogen ewuketshezi asetshenziswa kabanzi ezindaweni zokugcina izinto emikhakheni yezokwelapha ngemithi, isayensi yezolimo, kanye nemboni. Lawa matangi angasetshenziswa ngezindlela ezimbili: ukugcinwa kwesigaba somusi kanye nokugcinwa kwesigaba soketshezi, ngalinye linezinzuzo kanye nokungalungi kwalo okuhlukile.
I. Izinzuzo kanye nokungalungi kokugcinwa kwesigaba somusi emathangini e-nitrogen ewuketshezi:
Ukugcinwa kwesigaba somusi kuhilela ukuguqula i-nitrogen ewuketshezi ibe yisimo segesi esigcinwe ngaphakathi ethangini.
Izinzuzo:
a. Ukulungela: Ukugcinwa kwesigaba somusi kususa ukukhathazeka mayelana nokuhwamuka kanye nokulawulwa kwezinga lokushisa kwe-nitrogen ewuketshezi, okwenza ukusebenza kube lula futhi kube lula kakhudlwana.
b. Ukuphepha: Njengoba i-nitrogen ewuketshezi isesimweni segesi, ingozi yokuvuza koketshezi iyancishiswa, okwandisa ukuphepha.
c. Ukuguquguquka: Indawo yokugcina umhwamuko ifanelekela ukugcina inani elikhulu lamasampula, njengezibonelo zezinto eziphilayo kanye nembewu yezolimo.
Okubi:
a. Ukulahleka kokuhwamuka: Ngenxa yesilinganiso esiphezulu sokuhwamuka kwe-nitrogen ewuketshezi, ukugcinwa kwesikhathi eside kwesigaba somusi kungaholela ekulahlekelweni yi-nitrogen, okwandise izindleko zokusebenza.
b. Isikhathi sokugcina esilinganiselwe: Uma kuqhathaniswa nesitoreji sesigaba soketshezi, isitoreji sesigaba somusi sinesikhathi esifushane sokulondolozwa kwesampula.
II. Izinzuzo kanye nokungalungi kokugcinwa kwesigaba soketshezi emathangini e-nitrogen ewuketshezi:
Ukugcinwa kwesigaba soketshezi kuhilela ukugcina ngqo i-nitrogen ewuketshezi ethangini.
Izinzuzo:
a. Isitoreji esinobuningi obukhulu: Isitoreji sesigaba soketshezi singagcina inani elikhulu le-nitrogen ewuketshezi endaweni encane, okwandisa ubuningi besitoreji.
b. Ukulondolozwa kwesikhathi eside: Uma kuqhathaniswa nokugcinwa kwesigaba somusi, ukugcinwa kwesigaba soketshezi kungagcina amasampula isikhathi eside, kunciphisa ukulahleka kwesampula.
c. Izindleko zokugcina eziphansi: Isitoreji sesigaba soketshezi sisebenza kahle kakhulu uma kuqhathaniswa nesitoreji sesigaba somusi.
Okubi:
a. Ukulawulwa kwezinga lokushisa: Kudingeka ukulawulwa kwezinga lokushisa okuqinile ukuze kugcinwe uketshezi ukuze kuvinjelwe ukuhwamuka ngokweqile kanye nokubanda kwesampula.
b. Izingozi zokuphepha: Ukugcinwa kwesigaba soketshezi kuhilela ukuthintana ngqo ne-nitrogen ewuketshezi, okudala izingozi zokuvuza nokusha kwe-nitrogen, okudinga ukunakwa okukhethekile ezinqubweni zokuphepha.
III. Ukusetshenziswa kwesigaba soketshezi kanye nesitoreji sesigaba somusi:
Isigaba soketshezi kanye nesigaba sokugcina umusi kufeza izinjongo ezahlukene ezinhlosweni ezahlukene.
Ukusetshenziswa kwesitoreji sesigaba soketshezi:
a. I-Biomedicine: Isitoreji sesigaba soketshezi sisetshenziswa kabanzi kwi-biomedicine ukulondoloza amasampula ebhayoloji, amaseli, izicubu, njll., okusekela ucwaningo lwezokwelapha kanye nokuxilongwa.
b. Ibhayoloji yezolimo: Ososayensi bezolimo basebenzisa isitoreji sesigaba soketshezi ukulondoloza imbewu ebalulekile, impova, kanye nama-embryo aqandisiwe, ukuvikela izinsiza zofuzo zezitshalo nokuthuthukisa izinhlobo.
c. Ukugcinwa kwemithi yokugoma: Ukugcinwa kwemithi yokugoma ngesigaba soketshezi kuyindlela evamile yokugcina imithi yokugoma, ukuqinisekisa ukuzinza kwayo kwesikhathi eside kanye nokusebenza kwayo kahle.
d. I-Biotechnology: Ku-biotechnology, isitoreji sesigaba soketshezi sisetshenziselwa ukulondoloza amabhange ezakhi zofuzo, ama-enzyme, ama-antibodies, kanye nezinye izinto ezibalulekile eziphilayo.
Ukusetshenziswa kwesitoreji sesigaba somusi:
a. Amalabhorethri okukhulisa amaseli: Emalabhorethri okukhulisa amaseli, isitoreji sesigaba somusi sifanelekela ukugcinwa kwesikhashana kwemigqa yamaseli kanye nokukhula kwamaseli.
b. Ukugcinwa kwesampula yesikhashana: Kumasampula esikhashana noma lawo angadingi ukugcinwa isikhathi eside, ukugcinwa kwesigaba somusi kunikeza ikhambi lokugcina elisheshayo nelilula.
c. Ukuhlolwa okunezidingo eziphansi zokuqandisa: Kokuhlolwa okunezidingo ezingenzima zokuqandisa, isitoreji sesigaba somusi siyindlela engabizi kakhulu.
Amathangi e-nitrogen ewuketshezi anesigaba somusi kanye nesigaba soketshezi ngalinye linezinzuzo kanye nokubi kwalo. Ukukhetha phakathi kwezindlela zokugcina kuncike ezimweni ezithile zokusetshenziswa kanye nezidingo. Isitoreji sesigaba soketshezi sifanelekela isitoreji sesikhathi eside, isitoreji esinobuningi obukhulu, kanye nezimo ezinezidingo eziphezulu zomnotho. Ngakolunye uhlangothi, isitoreji sesigaba somusi silula kakhulu, sifanelekela isitoreji sesikhashana kanye nezimo ezinezidingo eziphansi zokuqandisa. Ezisetshenzisweni ezisebenzayo, ukukhetha indlela yokugcina efanele ngokusekelwe ezicini zesampula kanye nezidingo zokugcina kuzofaka isandla ekuthuthukisweni kokusebenza kahle kanye nekhwalithi yesampula.
