Imboni yezolimo iyisizinda sokuqanjwa kabusha kwesayensi nezobuchwepheshe.Amapulazi esimanje kanye neminye imisebenzi yezolimo ihluke kakhulu kuneyakudala.
Ochwepheshe kulo mkhakha bavame ukuzimisela ukusebenzisa ubuchwepheshe obusha ngezizathu ezahlukahlukene.Ubuchwepheshe bungasiza ukwenza imisebenzi isebenze kahle, ivumele abalimi ukuthi benze okwengeziwe ngesikhathi esincane.
Njengoba inani labantu likhula, ukukhiqizwa kokudla kuyaqhubeka kwanda, konke okuncike kumanyolo wamakhemikhali.
Inhloso enkulu ukuthi abalimi banciphise inani lomanyolo abawusebenzisayo ngenkathi bekhulisa isivuno.
Khumbula ukuthi ezinye izitshalo zidinga umanyolo owengeziwe, njengokolo.
Umanyolo uyinoma iyiphi into engezwa enhlabathini ukuze ikhuthaze ukukhula kwezitshalo futhi isiyingxenye ebalulekile yokukhiqiza kwezolimo, ikakhulukazi ngokusungulwa kwezimboni.Kunezinhlobo eziningi zikamanyolo, okuhlanganisa amaminerali, ama-organic kanye nomanyolo wezimboni.Iningi liqukethe izakhi ezintathu ezibalulekile: i-nitrogen, i-phosphorus ne-potassium.
Ngeshwa, akuyona yonke i-nitrogen efinyelela izitshalo ngokwazo.Eqinisweni, ama-50% kuphela e-nitrogen kumanyolo asetshenziswa izitshalo emapulazini.
Ukulahleka kwe-nitrogen kuyinkinga yemvelo njengoba ingena emkhathini nasemizimbeni yamanzi njengamachibi, imifula, imifudlana nolwandle.Kuyaqapheleka futhi ukuthi kwezolimo zanamuhla, umanyolo we-nitrogen uvame ukusetshenziswa.
Amanye ama-microorganisms emhlabathini angaguqula i-nitrogen ibe amanye amagesi ane-nitrogen abizwa ngokuthi ama-greenhouse gases (GHGs).Ukwenyuka kwamazinga okukhishwa kwegesi ebamba ukushisa emkhathini kuholela ekufudumaleni komhlaba futhi, ekugcineni, nokushintsha kwesimo sezulu.Ngaphezu kwalokho, i-nitrous oxide (igesi ebamba ukushisa) iphumelela kakhulu kune-carbon dioxide.
Zonke lezi zici zingaba nomthelela omubi emvelweni.Ama-fertilizer aqukethe i-nitrogen ayinkemba esika nhlangothi zombili: abalulekile ekukhuleni kwezitshalo, kodwa i-nitrogen eyeqile ingadedelwa emoyeni futhi ibangele inani lemiphumela emibi empilweni yomuntu nezilwane.
Njengoba abathengi abaningi besebenzisa izindlela zokuphila eziluhlaza, izinkampani kuzo zonke izimboni zibheke ukusebenzisa izindlela ezizinzile ukuze zibe nomthelela omuhle emvelweni.
Abalimi bazokwazi ukunciphisa inani likamanyolo wamakhemikhali asetshenziswa ekukhiqizeni izitshalo ngaphandle kokuphazamisa isivuno.
Abalimi bangakwazi ukulungisa izindlela zabo zokuvundisa ngokusekelwe ezidingweni ezithile zezitshalo zabo kanye nemiphumela abafuna ukuyizuza.
