Ukuze sikwazi ukugcina umkhiqizo omkhulu, kubalulekile ukuthi sibheke imininingwane edingekayo kusuka uwusebenzisa kanjani futhi nini umquba ketshezi ezitshalweni zethu, ngoba ukuze bondleke kahle ngokwanele, kufanele sazi ukuthi yisiphi isikhathi esifanele sokukwazi ukwenza lo msebenzi.
Kunconywa futhi kubaluleke kakhulu ukuthi sihlakulele isu esingalisebenzisa ngalo ukunciphisa inani lezakhamzimba ukuthi izitshalo zilahlekelwe, zikhulise ukusebenza kwazo futhi ngasikhathi sinye zigweme umonakalo omkhulu ongaba khona emvelweni.
Ngakolunye uhlangothi, kuyadingeka ukuthi sisho ukuthi uma sisebenzisa umanyolo owuketshezi okungenani ngesikhathi esishiwo, izakhi zomzimba ezibalulekile zingalahleka, umanyolo ungamoshwa singadala umonakalo ezitshalweni. Lokhu kwenzeka ngenxa yezakhi zikamanyolo esifuna ukuzisebenzisa kanye nokuphendula okungenzeka kwenzeke ngemvelo.
Uwusebenzisa nini umquba wamanzi?
Njengabantu abaningi, siyakwazi lokho kuye ngezitshalo ngukuthi sizosebenzisa inani elidingekayo ezigabeni ezahlukahlukene zokukhula kwalo. Sidinga ukwazi isitshalo sikusiphi isigaba sokukhula, ukuze sikwazi ukufaka umanyolo oketshezi ngendlela eyiyo.
Ngale ndlela, isikhathi esifanele kithi faka umquba oketshezi kuzochazwa ngephethini lapho izakhamzimba zingena khona esitshalweni futhi kuleso sitshalo, isakhi ngasinye sakha iphethini ekhulayo ngayinye Ezitshalweni, ngale ndlela, kunconywa ukuthi ukusetshenziswa kukamanyolo kuhlukaniswe kahle ngesikhathi esibonisiwe, ngoba lokhu kusiza isivuno ukuthi sikhule kakhulu.
Uwusebenzisa kanjani umquba ketshezi?
Izitshalo bangaba namazinga ahlukene lapho bengabekezelela khona usawoti. Uma leli zinga likasawoti liphakeme kakhulu kunalokho isivuno esingakubekezelela, isivuno singathinteka nomphumela waso uzoqala ukuncipha.
Ngakho-ke singazi lithini inani elidingekayo likamanyolo oketshezi esingakusebenzisa ekulimeni kwethu, okudingeka sikwenze ukwazi umkhawulo wamandla ukulima kwethu okungakubekezelela.
Ngaphezu kwalokhu, kwehlukaniswa izicelo zomquba Kungaba wusizo olukhulu ukuze sigweme ukulimala ezitshalweni zethu okudalwa wusawoti omningi emhlabathini futhi sikwazi nokwandisa inani lembewu ehluma esitshalweni. Ngakolunye uhlangothi futhi ukuze sikwazi ukunciphisa ukucindezeleka kasawoti oshiwo, kudingekile ukuthi sifake inani elincane likamanyolo owuketshezi ngezikhathi ezincane.
Uwusebenzisa nini umanyolo wamanzi oqukethe i-nitrogen?
Ukuphathwa kukamanyolo oketshezi oqukethe inani elikhulu le-nitrogen ezingxenyeni zalo kudinga ukuthi siqaphele kakhulu lapho uyisebenzisa, ngoba le nto intekenteke impela ngoba izakhamzimba zingalahleka emhlabathini.
Kumele sinake ukuthi le ngxenye ilahlekile ngenxa yokwehla kwamandla kagesi, ukuguguleka kwenhlabathi, ukuvuza kwamanzi, ukugeleza kwamanzi nokudonswa kwamanzi, okuwukuguqulwa indlela yebhayoloji ye-nitrate kugesi ye-nitrogen, i-nitrous oxide ne-nitric oxide.
Uma singayisebenzisi ngendlela efanele, i-nitrogen ingena kalula emhlabathini ezinesihlabathi impela uma kuqhathaniswa nenhlabathi enokuthungwa okuhle futhi ukulahleka okungaba khona kungaba cishe ama-60% enani esilisebenzisayo esivinini.
Uma umanyolo oqukethe i-nitrogen equkethe uketshezi ufakwa ngaphambi kwesikhathi noma ngesikhathi lapho isitshalo singasidingi khona, iningi lingalahleka ngaphambi kokuba isivuno sibe nethuba lokumunca, ukuze kuxazululwe lokhu, kufanele sinciphise unomphela we-nitrogen emhlabeni ngaphambi kokuba isitshalo sibe nethuba lokusimunca.
Ukufaka lesi sakhi ngendlela eyiqhezu kanye nalezo esesishilo yiyona enconywe kakhulu, ngoba kunjalo kunciphisa ithuba lokuthi into ilahleke futhi imele uhlelo lokusebenza olusebenza kahle.
